Stephen Posted November 15 Report Posted November 15 Aircraft Review : Gulfstream 650/650ER by AKD Studios In the world of privilege, those whom are superior to us mere mortals, then the word "Gulfstream" is their daily transport. These private jets are the upper echelon of status, and the bigger, faster and the longer range of these niche machines, then the higher the status. AKD Design released X-Plane's Gulfstream G550 a couple of years ago in late 2022, the best dedicated Gulfstream for the X-Plane Simulator. Here is the release of the GLF 650, with including the GLF 650ER - Extended Range variant. The Gulfstream series is a complicated one, as the G600/G700/G800 Series was built upon the last series of G500/G550 Series, and those aircraft evolved out of the Gulfstream V as the GV-SP. So is the GLF 650 the biggest and fastest? not quite, as I said Gulfstreams are complicated and don't follow in order. The GLF 650 has a 7,000 nm range and a maximum speed of Mach 0.925 with 18 passengers, The GLF 700 Series has a 7,500 mn Range for 19 passengers in a longer cabin of 56ft. The GLF 800 is a hybrid of the two, it has the shorter (GLF 650) cabin at 46ft, but the more modern engines and the newer wing to cover a 8,000mn range, carrying 15-19 passengers. So the GLF 800 is best suited for the longest routes, while the GLF 700 maximizes cabin space for ultra-luxurious travel. The GLF 650 remains an excellent option for those who need luxury with substantial, but slightly less, range. But then the GLF 650ER spices it all up a little with the GLF 700, as it can cover the same 7,500nm range, so you can connect even more distant city pairs, such as Los Angeles to Melbourne or Hong Kong to New York nonstop. Otherwise the G650 and G650ER are basically the same aircraft except in one area, in that the G650ER holds more fuel and has a higher MTOW to support the extended range. But first just a couple of more statistics. If you have invested in the AKD GLF 550, then what is the difference between GLF 650? (noted here is the original G550 release). Unexpectedly the cabin is actually smaller in 46ft 10 inch (G550 50ft 1 inch), height is only one single inch higher. The range between them is 7,000nm to the G550 6,750nm, but speed is the same at Mach 0.85, the engine is different with the Rolls-Royce BR725 engines, with a maximum thrust of 16,900 lbf (75.2 kN). The BR725 50 inch (130 cm) fan with 24 swept blades is 2 in (5.1 cm) larger, and 4 dB quieter than the BR710 on the GLF 550. Overall the GLF 650 offers more cabin space, larger panoramic windows, and a lower cabin altitude (4,100 feet at high altitude) for enhanced comfort and reduced jet lag, so it is a step up in luxury, speed, and comfort from the GLF550. Both the G550 and G650 fly the same, feel the same actually, but the G650 does have a better initial climb rate of 4,000 fpm, compared to the G550 3,600 fpm, then both can climb easily at 2,000-3,000 fpm over 30,000ft to a ceiling of 51,000ft. They are impressive machines. The G650 cabin fit-out is different, more beige than the earlier G550 cream, the wood is changed from Teak to Walnut (a bit of a lighter wood). Chairs are actually smaller and more squarer than the wide G550 seating, but were as the G550 has abundant space, here the layout is far more better conceived, more realistic by design. With four forward club, twin club seats around a table, single club behind and only one sofa on the right rear. The lovely buffet with popup (animated) monitor, that shows the in-flight map is also better positioned mid-cabin. walnut highlights show the non-smoking/Seatbelt signs, and the front galley is very nice, with a marble worktop. There are two areas rear, first door is the washroom/toilet, rear is the large baggage area, with nets, a case, and the lower cargo hatch works for loading in the bags externally. I wasn't crazy about the G550 windows, they are better(ish) here, but not in an advanced way, still don't have any animated blinds either, I expected a step up here? From the X-Plane "Flight Configuration" menu you have the choice of both the GLF 650, and the GLF 650ER (Extended Range). So they are presented as separate aircraft. Externally the two G550 and G650 aircraft are not much if anything different, you would be pushed to separate them. Modeling wise they are very good, but certainly not in that high ultra realism factor we can now expect from X-Plane 12. The small issues are just that in being small, like the nosewheel lights (when off) and landing lights are not textured, or are blank. Not a good look at this level, and after two years, both G550 and G650 lighting should have been textured by now. Window surrounds are Lo-Res, but nice tinted glass. Problematic cabin windows does actually have glass, but it is extremely thin and not really reflective, so it all looks a bit holey... required is say a window tint or scratches to highlight the glass? There are two (male and female) pilots flying the aircraft, and quality pilots they are, but they are not animated. G650 has a highly swept high aspect ratio wing with a 36-degree sweep angle, which reduces drag and enables high-speed, gives you an efficient cruise, the wing incorporates composite materials for strength and to reduce weight. Lean and mean here, lovely curve is right up to the well done blended winglets. The G650 uses a Honeywell RE220(G) Auxiliary Power Unit, it provides high electrical power output and bleed air to the aircraft. The RE220(G) is hidden away in the lower tail, but you can hear it running. Distinctive Gulfstream tail (high bulky forward) is well done, and looks realistic. The G650 rear section and tail is quite different from the G550, cleaner and without air vents, but well done here. BR725 engine pods are better than the AKD average G550 versions. Better fan detail is also all new, as is the rear exhaust detail. But I wasn't impressed by the poor internal fit, that showed in the surrounds of too much daylight? Reverser action is very basic, just a set of cans and no real detail. The nosewheel is exquisitely crafted, an amazing amount of small detail, down to strut, hydraulics, links and nuts, but the noted missing lighting glass still makes it feel all slightly unfinished? Twin rear assemblies are trailing link, a normal gear arrangement on these executive jets. Again all the modeling and detail is first rate. Here better than the G550, that was quite bland/unfinished. Inner gear doors however are wafer thin, and not very realistic, but the animation is excellent. As are the nice rubber tyres and quality inner wheel rims. Static Elements Externally you have a set of Static Elements, including pitot tags, chocks (all wheels) and two AKD logoed GPUs (Ground Power Units). Both the main entrance forward door and baggage hatch are nicely animated to open and close. Cockpit The cockpit (no seperation doors on Gulfstreams) makes it feel very exposed to the passengers. Inside the layout and feel is the Gulstream same, but different... if that makes sense? You quickly understand the Gulfstream layout, but the feel in here is far lighter in beige, than the overall dark grey of the G550, it is helped by the very nice orange head and armrests on the seats. Wall panels have the diamond patterned luxury feel as on the G650, but the "GulfStream" logo on the rear of the centre console is missing? Seats are the same, but slightly modified in they now have armrests, but oddly only the inner rests are animated? Outwardly they look great, but on closer inspection they are quite lumpy and hard in detail, seats are locked into place as well. Note the hanging rear jumpseat, shame it is not animated.... Yokes are slightly different from the G550, in the centre paper clip holder is missing, but look better. PTT (Push To Talk) works, but not the electric trim? You can hide both yokes via pressing the instrument panel behind. Note the nice rudder pedals. Throttle quadrant is also the same, but again different... the handles on the G550 were chrome, here they are anodised, and note the "very" small AutoThrust (working) disconnect button. Power on... and you get a startup/alignment sequence. There are three options here; Real, Short or Instant alignment, but the full procedure is worth watching. Flight Deck The Gulfstream integrated flight deck is based on the Honeywell's Primus Epic integrated avionics system. There are four huge 14-inch displays Active Matrix Liquid Crystal Display (AMLCD) that use the Next Generation Flight Management System (NGFMS). Basically they breakdown to the two external PFD (Primary Flight Displays), and the two inner MFD (Muliti-Functional Displays). Note, this is NOT the "Symmetry Flight Deck", that has Touchscreens and Side-Stick controllers. The G550 uses the "PlaneView" Cockpit series, were as the G650 uses the upgraded "PlaneView II" system with the Cursor Control Devices (CCD), Predictive Landing Performance System (PLPS) and HUD "Dual Head-Up Display Option"... not included here on the PlaneView ll are the Synthetic Vision System (SVS), Enhanced Vision System (EVS) and Automatic Emergency Descent Mode (EDM). But provided however is a single pilot HUD, it works, but looks very dated to the latest Laminar Research default HUD, I expect it will be updated in an update. The panel layout is basically the same as the G550, but there is a slight difference with the Gulfstream specific glareshield "Switch Panel Unit" (SPU) on the G650 and G700 series. There is an added element of the SMC or "Standby Multifunction Controller" that shows the backup instruments in the SPU, it is activated by the "STANDBY" button under the SPU selection buttons... ... if the SMC is switched off you get the Aircraft's registration number (a nice handy touch), and the usual SPU menu selections. The SPU is basically a simple push-button controller and it is easy to access and set, the menus are shown on the SPU Display. Selections include; PFD, MAP, SENSOR, FLT REF, TEST, CHKLIST - SYSTEM, 1/6 - 2/3, TRS, NAV, HUD. By my estimation about 70% of the SPU system is currently only working? but this is a very deep system. Upper left buttons select the system area you want to access, and the right display has selection buttons to access the item, it is complex, but simple in the same instance. Once you work out where each selection is (or have a printed guide) then the system is easy to use. Here you can select 2/3 of the PFD (or have the engine or data readouts left 3rd of the screen) or use FULL which gives you the full basic flight instruments Artificial Horizon top and the Horizontal Situation Indicator lower. Artificial Horizon, Speed and Altitude tapes, Bank roll scale and roll pointer, Vertical Speed markers, Pitch markers, ILS bars and AOA (Angle of Attack) guide. There are 3 HSI selections with 120/180/360º options. The left panel systems is separated into two sections selected from the Switch Panel Unit, in DU 1 "Upper" and "Lower". These selections can be changed to show other system items, including; AC/DC Power, APU/Bleed, Brakes, ECS/Press (Environmental), Eng Start, FLT Controls and traffic. Selections are done by pressing the corresponding button to the line. NEXT gives you more options; <Cameras, CAS (Crew Alerting System), Checklist, Comp (Comprehensive) Eng, Pri (Primary) Eng, Sec (Secondary) Eng and Waypoint List... RETURN takes you back to the first menu order. These menu options are available on all four DU units. The other two DUs are set in the two centre displays DU 2 (Lower) and DU3 (Lower). You have also in the central DU 3 and DU 4 displays, both have built in menus for MAP/Navigation. Provided are; Map Data, Aircraft Centre (Heading or Plan modes), Hdg, Prev, Next (waypoints), World and Map which is also on the systems menu Left menu allows you to show Map data (Airports, VORs, NDBs...). The right menu shows aircraft diagrams for; AC Power, DC Power, Doors, Fuel, Hydraulic, MAP, CMC, ECS/Press, FLT Controls, Summary. And either DU 3 or 4 displays can be used via both menus. The diagram layouts are more detailed than the G550, plus the camera is now in colour. DU 3 upper right has an Engine Readout panel including N1 (Fan Speed), N2 (Core Speed) EGT (Exhaust Gas Temperature), Fuel Flow, ITT (Interstage Turbine Temperature), Oil Pressure and Temperature, hydraulic Pressure, Fuel Temps and Fuel Quantity. DU 4 has an upper left panel for the Crew Alerting System (CAS), and lower left is the excellent built in checklist with navigation selections. True to the G650 system, menu navigation is via a three pronged PlaneView II CCD cursor (arrowed) All four DUs (Display Units) will pop-out via the X-Plane Banner Menu "GLF 650ER AKD XP12". The G650 CAS or "Crew Alerting System" is excellent as it categorises alerts into four levels: Warning (red), Caution (Yellow), Advisory (Blue), and Status (White). Can also be labeled as the Centralised Warning Panel (CWP) on the DU4. • Warnings represent immediate action items (e.g., engine fire) and are often associated with aural alerts. • Cautions indicate conditions that require attention but aren’t immediately critical. • Advisories provide information that may affect the flight but generally do not require immediate action. • Status messages give general information or notifications on system states. Flight Management System (FMS), originally in the AKD GLF 550 it had the standard Laminar default FMS, and very basic it was... But here in the G650 we have a more dedicated FMS, it's still a sort of hybrid, so it is not totally authentic to the Honeywell Primus Epic installed in a G650, it however is quite good and far, far better in detail and data than the default installation. All three MCDU units pop-out via the banner menu "GLF 650ER AKD XP12". The IDENT and NAV INDEX are very authentic, but you can still insert a standard X-Plane .fms route from X-Plane. Manual entry of the flightplan is also possible, even with Co-Ords DEPARTURE (SID) and ARRIVAL (STAR) are also available and can be tuned and ACTIVATED to your preferences. So Flightplan creation and editing is very quick and easy, basically you load in your .fms flightplan, add in the DEP and ARR procedures and your done! You can check the Flightplan (PLAN) by going to the Switch Panel Unit and selecting MAP, then NORTH to activate the PLAN mode. Then press PREV or NEXT to navigate the Flightplan... If the need be, you can also finely adjust the MAP screen via tabs, top, bottom and both sides via the CCD cursor directly on the DU Display. There are also three PROG (Progress) pages with a significant amount of route and flight data. The Automatic Flight Control System (AFCS) is positioned in the glareshield contained each end by each Switch Panel Unit (SPU) system, and the WARNING panel is far left and right. AFCS is dual system, fail-operational, for both the Autopilot (AP) and the Auto Throttle (AT) subsystems. This is accomplished by hosting each system in a different modular avionics unit with two lanes in separate processors. The purpose of the AFCS is to provide Flight Director (FD), AP yaw damper and trim functions. The autoflight system receives computed lateral (roll) and vertical (pitch) steering commands from the FD system for the autopilot and for display on the Primary Flight Display (PFD). In the event the AP is disengaged the pilot can manually fly the steering commands presented on the PFD. The AP and AT systems make up the subsystems of the autoflight system. Layout and use is identical to the GLF 550. Overhead Panel (OHP) is really well set out and easy to use. Digital numbers are all used in the readouts. Systems covered are; the Electrical system with all its buses, Full Fire Protection system, the full Hydraulic system, Gulfstream Fuel system and APU system and start up timing. The main twin-throttles and rear reverser levers are as noted now an anodised, design, look nice, nice to use. Set each side are the standard Air-brake and Flap levers UP-10-20 (T/O and APP) - 39º (Down). Rear pedestal is all electric trims and MCDU 3, nicely done is the use of a FMS frame to hold the Radio settings, a simple but clever way of doing it. Although the MCDU 3 holds the RADIO frequencies, the Radio controls are on both side panels with the lighting controls. There are EFB/Tablets available for both the Pilot and First Officer, both can be separately accessed via the Banner Menu "GLF 650ER AKD XP12". As a note there is one other Menu option on the Banner Menu, this is the "IRS instant Align", to do a quick system alignment. There are nine menu tabs; Fuel Payload, GND (Ground), AviTab, Flight Plan, PERF (Performance) Calculator, Settings, Checklists and Audio Volume and Cabin Lights. Most of the EFB layout is the same as the earlier G550, but there are a few differences. FUEL : Here you can set your fuel load (Kgs and Lbs), Set Cargo, Set Payload, Passengers, and even the passenger weight. The changes are shown in fuel load, GW (Gross Weight) and ZFW (Zero Fuel Weight. Three options are also available; Reset Data, Set, and Insert Simbrief Data. You can now load in your Simbrief data directly into the Fuel/Weight page, but have to press SET to align the Fuel and Payload weights (which is a little slow?) an instant load would be nice. You can scroll or Add + or Minus - any number to your liking (like extra fuel) When loaded you can then load your passengers by pressing "Boarding". Pressing "bring Passengers from terminal" will activate a very nice Mercedes bus, then load the passengers into the aircraft, when the bus will drive away, the opposite to deplane, or "Take passengers to terminal" is the reverse operation. This activity has had a lot of refinement over the last two years, earlier it was a Tesla 3 car, a scale too big, and the process was chunky, but this is now really well done, if waiting for the bus to arrive is a bit (okay a lot) slow. GND : There are a few options on the "Ground Handling Page" which are the Static Elements. Of which there is the GPU (Ground Power Unit) AC, but also noted a DC Unit, Main door and Main Door Lights, Chocks, Cargo Door... on the Static Elements Page there is; front L/G covers, Captain and F/O pitot covers, and Main L/G covers. Open ALL Doors and Close ALL Doors options are also available AviTab : AviTab (Plugin Required) is available and a nice to have. Flight Plan : This tab option is new from the G550, but the former METAR tab is now merged with the Flight Planning. Again you can "Inport Data from Simbrief" (Import Simbrief) to load in the current generated Brief, Flightplan and Fuel/Weights, then you can SET FUEL/PAYLOAD directly into the MCDU. This will set up the Departure and Approach speeds. NOTE: I couldn't find the Simbrief Profiles for the GLF 650? So the developer has provided two, one for each variant G650 and the G650ER, both are listed below, and are required as a custom G550 version won't work or be correct to the G650 performance. And four PERFORMANCE INIT pages... parts of the PREF are not yet completed, it looks like the VNAV section. PERF (Performance) Calculator : There is a two page comprehensive performance calculator that can take data from the FUEL and METAR pages and fill in the required data, including : (Takeoff) DATA, AIRPORT INFO, TAKEOFF SPEEDS, FLAP LIMITS, (Landing) DATA, AIRPORT INFO, LANDING SPEEDS and FLAP SPEEDS. SETTINGS : In settings you can set the various aircraft options, including; IRS Alignment (Time) - Real/Short/Instant, Refuel (Time) Real/Short/Instant, Simbrief User ID, Pause on TOD (Top of Descent), EFB Units (Kg/Lbs), Aircraft Temp units (Cº/Fº), Aircraft Weight Units (Kg/Lbs), Sync (Baro), Nosewheel (Roll/Yaw/Tiller) and EFB Brightness. Second page includes (advanced); Tail Rego, Use Kill Objects, Disable LuaJIT, Static Elements on Startup and Main Door open on Startup. CHECKLIST : The checklist has been simplified, in that you now can't check off (green) items, otherwise navigation is still easy and the lists are through. SOUND : Sound panel is currently quite basic, with sliders for (Master) Volume, Exterior Volume, Interior Volume, Co-Pilot Volume and Radio Volume. CABIN LIGHTS : There are two pages of "Cabin Lighting" settings, the overhead lights, and diverse lighting. All can be either selected individually, or use the "Turn ON All lights' (Turn OFF also) to shortcut the cabin lighting, all can be adjusted for BRIGHTNESS via the sliders. ___________ Lighting The AKD G550 when released in lighting was a bit hit and miss, but a lot of development has completely changed this aspect. The Cockpit lighting has about 12 adjustment knobs, and now all of them work, and they cover basically every area. From Instrument dropdown, OHP, Centre Console, pilots side panels, yoke lights and overall cockpit lights. The vestibule area behind the cockpit is especially well done. As you know I like a certain cockpit sterile low lighting feel for takeoff and and landing, it is perfectly available here, but I will note was quite fiddly to get it right, not something you can adjust quickly? A neat feature is the text lighting on the yokes, high adjustment gives you white text, low adjustment the same orange text as the OHD and side panels. Cabin Cabin lighting is just sensational. We have seen the options, and the selections are upper and lower downlights, and the separate seat lighting. Again with all the adjustments, there are load of different cabin variations you can create. Bathroom and Baggage areas are excellent. Even with the cabin lighting off, and the vestibule lighting on, it looks and feels nice and comfy. External lighting The external lighting has been refined as well. It covers both landing lights with a "Pulse" option, nosewheel taxi lights, Navigation and Beacon/Strobe, tail lights, ICE/Wing and gear bay lights... Landing lights are still a bit over bright for my tastes, but otherwise very good... the forward cabin door also has built in lighting, looks excellent. A few GLF 650 flight notes I'm not crazy about the tight tiller, jiggly is more like it, and it is hard to taxi straight, the rudder pedals don't give you a lot of turning movement either, so the GLF 650 is a bit of a beast to taxi. You need to "Arm" the ground spoilers when you get to the runway, if not they stickup, but this will also give you a "Ground Spolier Unarmed" Caution until you get there. It is very easy to not to set the A/T (AutoThrust) were you get the "A/T not in Hold" Caution. The "Arm" selector is hidden on the left of the AFCS, the best way to find the hot-spot is to switch on the "View/Show Instrument Click Regions" Power up and your gone... with a combined thrust of 33,800 lbf from the BR725s. .... T/O flap is set at a high 20º, so you need to retract the flap to 10º almost immediately on leaving the runway, same with the retracting the gear to get yourself cleaned up as soon as possible. Then the Gulfstream will climb like no tomorrow at a 4000 fpm climbout, but 3,500 fpm is far more realistic. Remember the FMS selection is selected via the NAV button on the SPU... There is custom LNAV and VNAV. Climb, cruise and descend management with altitude and speed restrictions, and even RNAV Approaches are available. You have a massive, almost Concorde ceiling at 51,000ft with this Gulfstream, so those impressive climb numbers are required, and you can reach that FL510 altitude at around 25 minutes under optimal conditions. At the really short 309nm distance between Luxembourg and Biggin Hill, FL320 is also still available, so we are not certainly pushing the GLF 650 anywhere near it's impressive credentials... You have to love this... a Gulfstream and X-Plane 12, Heaven. Sounds are particularly good, with a 3D sound engine with stereo dynamics, lovely wind and control surfaces sounds that are different in the cabin than the flightdeck, the cockpit ambient sounds are excellent with no loops or repetitive droning and the systems have custom alerts. There are custom PA Sounds in Polish and English, but I couldn't find were you activated them... overall the aural package is very good. There are only two liveries in the package, N650GY and SP-TOP, but there is a paint-kit included. There is also a dedicated AKD GLF650 liveries page here: Liveries for the GLF650, with loads of choices. Other features include a custom GPWS (Ground Proximity Warning System), TCAS (Traffic alert and Collision Avoidance System) and a very good custom Pressurization, Oxygen and Air Conditioning system, again required for that high altitude. You can go down as fast as you can go up! You can descend at 3,000 to 4,000 feet per minute (fpm) during normal descent phases, but even 5,000 fpm is possible, though this is generally reserved for emergency situations. The passengers get quite a ride... The aircraft has a very good "Autotune" for both the ILS and local VOR frequencies (115.10 BIG), so if you need to do a manual ILS or VOR tuning, then it must be turned off via the Radio page, if not the frequencies are locked in. There is a bit of a trick to landing the G650, it is to get the most minimal speed you can for landing, if not it is a bit of a handful on the tarmac. Whatever you can get away with you will accept, here it is a noted 136 knts approach, but closer to the runway I am down as low as 127 knts, and still airborne.... you just keep lowering and nudging the throttle rearwards as you get closer and closer to the threshold. Then hold that final flare and let the Gulfstream sink as smoothly as you can... ... and touch! Then hit the "Cans" and you will find the reverse thrust is very effective, thankfully as you require a runway landing distance of approximately 3,000 feet (914 meters) under ideal conditions (at sea level, standard temperature, and no wind) when fully loaded. Biggin Hill 03/21 is only 5925ft (1806m) so it is quite tight if you leave the landing too late. And the G650 can be a bit tricky on those final moments and when down on the hard-stuff, hence that slow landing speed.... so it requires skill, in the takeoff and landing phases. But this is a very nice genuine Gulfstream dream machine. _____________ Summary In world of the elite, then the word of Gulfstream is the biggest token you can play in this upper exclusive club. The Gulfstream 650 has a 7,000 nm range and a maximum speed of Mach 0.925 with 18 passengers, Gulfstream 650ER however spices it all up a little with the GLF 700, as it can cover the same 7,500nm range, so you can connect even more distant city pairs. G650ER holds more fuel and has a higher MTOW to support the extended range. This aircraft is a major global trotting machine with both oceanic and transcontinental in range, it can fly high as well to an almost sub-orbital 51,000ft. AKD Design released X-Plane's Gulfstream G550 a couple of years ago in late 2022, the best dedicated Gulfstream for the X-Plane Simulator. Here is the release of the GLF 650, with also includes the GLF 650ER - Extended Range variant in this package. The Gulfstream G550 was a first time project by AKD Studios and obviously they had to pick an extremely complex aircraft to start with. So we found at the time the G550 was a bit underdeveloped, but to be fair, AKD has been one of the most prolific developers, with delivering almost monthly, even weekly sometimes in updates. So the development of the not only the original G550, but also the features of the G650 are now all excellent. Impressive in Gulfstream systems, the GLF 550 and this G650 are comprehensive and are excellent in operation, including the excellent Gulfstream "Display controllers" (menus) and all DUIs are covered by a four display screen arrangement based on the Honeywell's Primus Epic integrated avionics system, notable is that this is not the Symmetry Flight Deck in the GLF 650, but the "PlaneView II" system with the Cursor Control Devices, and that aspect is well done here. Also custom CAS (warnings), Ice and rain protection system (X-Plane 12), IRS system and a full (menu) Electronic Flight Bag (EFB), also notable is the FMS (Flight Management System) is now also custom, GPWS (Ground Proximity Warning System), TCAS (Traffic alert and Collision Avoidance System and a custom Pressurization, Oxygen and Air Conditioning system... it's an impressive list. Modeling is now very good but your not going to get the extreme X-Plane 12 Ultra quality here, a lot has been refined and updated over the two years, but a few niggles still remain... those cabin windows are still average and still have no blinds, the non-texturing of the main and taxi lighting is actually now becoming bewildering, and internal engine detail has too much light gaps from certain angles. But the cockpit and cabin lighting is excellent and highly adjustable, sounds are very good as well, the cabin layout is better here than the G550, and cockpit seats have very nice orange highlights. Personally I absolutely love these Gulfstreams from AKD Studios. X-Plane has always wanted really excellent transoceanic Private Jets for decades, and here they are available to X-Plane users, the G650 is also available in X-Plane 11. The price for the G560 is a little higher than the earlier released G550, but you get a lot for your investment, however if you own the GLF550 by AKD, you can get this GLF650 for a 25% off the price. Either way for your money you get a lot of aircraft with it's Gulfstream related systems and extensive list of features... Highly recommended. X-PlaneReviews has also published the AKD Designs interview by Dominic Smith (Also on the X-Plane.Org) to get a background on this interesting developer. ________________________________ The Gulfstream 650/650ER by AKD Studio is NOW available here at the X-Plane.OrgStore GLF650 - Ultimate Business Jet by AKD Studio Price is US$44.95 Requirements X-Plane 12 or X-Plane 11 Windows, Mac (even native M1, M2,etc Macs) or Linux 8 GB+ VRAM Recommended Download Size: 1 GB Current version : 1.01 (November 4th 2024) PS: If you own the GLF550 by AKD, you can get this GLF650 for a 25%.
