The Boeing (formerly McDonnell Douglas) C-17 Globemaster III is a large military transport aircraft manufactured by Boeing Integrated Defense Systems.

Downloading and using aircraft

First Note and installation of aircraft

First note, even though the README says to install FGUK before installing the aircraft, this is optional, its so you can see object like scenery inside the aircraft and sometimes utilize them, they do not affect the performance of the aircraft itself. The aircraft can and does work as intended without the FGUK. If you wish to download the FGUK the link is https://www.fguk.me/hangar/fguk-payloads-package/ . As with all other user downloaded aircraft, after downloading the aircraft, remember to remove "-master" from the unzipped file name before placing it into a folder that FlightGear searches for aircrafts in.

The repo for the aircraft is : https://github.com/FGMEMBERS/C-17 The direct download for the aircraft is : https://github.com/FGMEMBERS/C-17/archive/refs/heads/master.zip

Selecting the aircraft

There is an issue where 3 globemasters will be listed. DO Not use the first one, the application will crash as there is an accidental reference to a third aircraft somewhere in the code. The ones to use are the second or third. The second one is for solo. The third one is for MP.

V Speeds

The V speeds and some other info for this aircraft can be found here. https://www.cram.com/flashcards/c-17-speeds-5576661

Other facts such as weights and range and ect

That information can be found here. https://www.boeing.com/defense/c-17-globemaster-iii/#/technical-specifications


The following are the flaps. They are listed bellow in the order of the number of times "]" has been pressed.

There is no push-back available on this aircraft. To do a push-back like procedure, use reverse thrust.


There is no throttle levers, to see the amount of throttle being used, you will have to use FlightGear's general HUD by pressing "H". The HUD that is displayed on the aircraft (different from FlightGear's general HUD, and is similar to the HUD found on the 787), does not show that information. The HUD on the aircraft, is infact the only instrument that is "tangibly" readable for knowing heading, Ground Speed, altitude, and Yaw. There is a standard altitude meter that does work, but the numbers are way to small to read thus making the aircraft's or Flightgear's HUD the only source of knowing the current altitude. Also the compass screen on the avionics panel, does not move regardless of how much you turn the aircraft, thus the aircraft's and FlightGear's general HUD can only provide that information.

For the Auto Pilot, it is a two step process, which also requires pausing the simulation before activating the autopilot(VNav and LNav are not always guaranteed to start by hitting the corresponding AP buttons on panel). To use the simplest method if you already are using flight manager, and GPS settings are set, there is no need to pause, hit CMD 1 and then LNAV then VNAV.

For manual AP config, hit CMD 1 then pause "p". Then go to Autopilot settings in the menu, and enter the desired config, then unpause. The knobs on the AP panel are clumsy, and there is no Vertical Speed slider.

The external lights are always on. There is no tiller steering, so for tiller on ground, use "Enter" or "Insert".

Note about landing and spoilers

Apparently the code for spoilers is implemented into the aircraft, however there is no animation for the spoilers, nor is there any indication of spoilers being activated. Thus one may not realize that the spoilers have been activated or not. Thus be careful when doing "cntrl - b" and remember the number of time it has been done. Odd number of times mean spoilers are in the active position, while even number of times means its not.

To Do

  • Spoiler animation or some form of panel message of activation.
  • Make compass on avionics panel usable.
  • Push-back
  • Improve thrust reverser animation.
  • Better AP panel.
  • According to some images on Boeing C-17 Globemaster III This is a link to a Wikipedia article, the main avionic map panel is similar to that of that of the Boeing 777. Especiallyin this image it shows the pilots avionic screen is almost basically like 777 pilot's avionic screen. (the image shows it is set to either "ILS" or "VOR" mode presentation, not the default map mode FlightGear sets all Boeing pilot avionic screen to by default. ) https://commons.wikimedia.org/wiki/File:Cockpit_of_a_RAAF_C-17_Globemaster_in_2014.jpg
