G550 - Landing gear and Brakes
The minimum indicated accumulator pressure to set the brakes and hold the aircraft is _____, assuming the correct nitrogen precharge exists.
If the indicated pressure is below 3000 psi, the crew may elect to recharge the accumulator by turning on the auxiliary hydraulic pump.
To stop the aircraft in the event of brake hydraulic system failure, you should pull up on the handle for metered braking. Activation of this handle provides graduated parking brake or emergency braking as required with no antiskid available to the brakes.
The gear may also be extended through use of the emergency gear extension system, which supplies pneumatic pressure to extend the gear.
The emergency extension T-handle is located on the forward side of the copilot’s side panel
Minimum turning radius for a 180-degree turn is 62 feet (19 m).
The nosewheel steering system uses:
Minimum parking brake accumulator pressure during preflight (precharge) at 22 deg.C (70 deg.F) is:
The auxiliary hydraulic system charges the accumulator to 3,000 psi whenever the system is energized
The nose gear is enclosed by two electrically operated clamshell doors, along with a fairing door mechanically attached to the strut.
The nose gear is enclosed by two hydraulically operated clamshell doors.
If the nosewheel steering is selected OFF, a 'Steer by Wire OFF' CAS will be displayed.
If only one landing gear will extend, it is recommended that the landing will be made in what configuration?
During normal operation of the nosewheel steering system, the pilot has full command authority over the angle of the nosewheel up to _____ when using the handwheel tiller assembly.
The maximum tiller steering value of 80 degrees left and right at full tiller deflection is reduced by groundspeed. This system uses IRS 1 or 2, so no single IRS failure will affect this system.

The fault warning computer logic considers the aircraft airborne if:
If only one main landing gear will extend, it is recommended that the landing gear be made in what configuration?
Emergency extension nitrogen pressure should be _____ at 21 deg.C (70 deg.F).
Two emergency landing gear bottles, which are serviced with 3,100 psi dry nitrogen, are used to pneumatically extend the landing gear.
Brake Overheat message appears on the CAS for any brake that has a temperature in excess of _____.
The message remains active until that brake temperature has dropped below 600 deg. C.
The landing gear warning horn will sound, regardless of altitude or power lever position if the gear are not down and locked and:
The landing gear can be extended and retracted using:
If the left system engine-driven pump fails (or if the left engine is shut down), the gear may be operated normally by utilizing the hydraulic power transfer unit (PTU).
