|---|---|---|---|---|---|
| How is the landing gear extended and retracted? | • Electrically commanded and hydraulically actuated
🗑
|
||||
| When will the aural warning for the landing gear sound? | • If the gear is not down and locked, and < 700’ RA and low TLA, or Any altitude with flaps set > 5
🗑
|
||||
| Can the landing gear aural warning be silenced by pushing the ‘LG WRN INHIB’ button? | • Only if both radio altimeters have failed
🗑
|
||||
| What are three landing gear extension modes? | • Normal LG lever DOWN• Electric override Bypasses PSEM to directly command selector valve• Alternate gear extension Manual uplock release opens free-fall sequencing valve
🗑
|
||||
| What is the purpose of the DN LOCK RLS button on the landing gear lever? | • Mechanically releases the landing gear lever lock• Lock protects against inadvertent landing gear retraction when weight-on-wheels
🗑
|
||||
| What keeps the gear locked in position? | • Extended Downlock springs• Retracted Uplock hooks
🗑
|
||||
| Describe the landing gear indications? | • Green Down & locked• White Up & locked• Amber In transit• Red gear position & lever disagreement (20 sec grace period)
🗑
|
||||
| How do the landing gear doors actuate? | • Mechanically, during landing gear extension or retraction
🗑
|
||||
| How are the brakes commanded? | • Brake by Wire• Electrically commanded and hydraulically actuated• Pedal position transducers send brake requests to the BCM (Brake Control Module)
🗑

||||
| What hydraulic system(s) provide brake pressure? | • HYD 1 Outboard brakes• HYD 2 Inboard brakes• HYD 1 & 2 Parking/emergency brake
🗑
|
||||
| What protections are provided for braking? | • Touchdown No braking until 3 seconds or > 50 kts wheel speed after touchdown• Anti-skid Compares wheel speeds and releases pressure (inop <10 kts)• Locked-wheel Allows up to 33% differential braking for steering purposes (inop <30 kts)
🗑
|
||||
| How many applications will the parking/emergency brake provide? | • 6 applications
🗑
|
||||
| What stops the wheels from spinning during retraction? | • Main gear BCM applies brakes after weight-off-wheels• Nose gear Snubbers in the nose bay stop the wheels
🗑
|
||||
| Which hydraulic system controls the nosewheel steering? | • HYD 2
🗑
|
||||
| What are the limits for the nosewheel steering? | • Angle varies with ground speed• Up to 40 kts +76° • 41 to 100 kts Decreases linearly from 76° to 7°
🗑
