Landing Gear, Brakes, & Steering Flashcards
What does a NWS LIMIT EXCEEDED(C) CAS indicate, and what action should be taken?
Nosewheel has been turned beyond 120 degrees. Check shear pins. If broken then the nose wheel has exceeded 123 degrees and possible damage has occured.
How much steering authority is available with the tiller?
65 degrees.
How much steering authority is available with the rudder pedals?
7 degrees.
The nose gear is actuated by which Hydraulic System?
Left Hydraulic System
What centers the nose gear during retraction?
- Electrically by the Steering Control Unit
- Mechanically by cams on the top of the nose strut
Antiskid is available down to what speed?
10 knots
Why must we observe brake cooling times?
To ensure there is sufficient brake energy available to come to a complete stop within the charted distance if we reject a takeoff.
The landing gear is normally actuated by which hydraulic system?
Left Hydraulic System
Gear is held up by what?
Mechanical Uplocks
What do the brake accumulators provide us when loss of L and R hydraulic pressure?
1 continuous application to a complete stop
Parking brake accumulator has sufficient pressure for how many applications?
6
If a gear control or left hyd system failure occurs, how do we get the gear extended?
Alternate method through the checklist - pull the manual release handle “LG PULL”
What does the “LG PULL” handle do?
- Manually releases the uplocks (Nose and Main Gear)
- Actuates the dump valves (ports fluid pressure to the return side of actuator)
When should the “LG PULL” handle be stowed?
After landing and the gear pins installed
What also assists the main gear to be fully extended? (down and locked)
Main landing gear down lock assist accumulator
