The C17 Globemaster III has a very unique Landing Gear assembly configuration. The aircraft is equipped with a front, steerable gear with two wheels; and a main gear with two struts, three wheels on each strut. All wheels on the main gear assembly have braking mechanisms. The front wheels do not have brakes.
A complex and unique set of linkages and rotatory axles fold the gear into the reduced space in which they are retracted. The C17 has a gear design like no other aircraft.
On the real aircraft, Hydraulic Pressure from systems 2 or 3 is required to retract the gear.
A gear Retraction and Extension handle is located near the First Officer MFDs, and feature indicator lights displaying the gear status. Additionally, the handle lights up Red when the gear is moving. Gear status is also displayed on the MFD, Config page.
A test button lights up all the status lights to certify them being functional. Anti-skid system and auto Brake Temp monitoring is available to control the aircraft in aggressive braking conditions.
All 12 wheels on the main gear assembly feature individual braking. The brakes have active monitoring of their temperatures, that can be checked from the cockpit's MFD Config Page.
Autobraking is not available on the C17.
A brake pressure gauge accurately represents and monitors Braking Pressure in PSIx1000. This pressure is affected by the supply of Hyd Pressure on Hyd System #3, and decreases/increases slightly with braking action.
