|
1. What aides the crew in directional control during a jammed rudder condition?
|
Trim
control disconnects differential power |
|
|
2. The purpose of aileron and elevator flutter dampeners is:
|
Gives shock absorption to the buffeting forces of wind in flight, or to provide some mechanical advantage for maintenance on the ground
|
|
|
3. What Hydraulic system(s) power the Inboard Ground Spoilers?
|
3A/3B
|
|
|
4. What Hydraulic system(s) power the Left Aileron?
|
1A/B, 2A/B
|
|
|
5. What is the Flight Spoiler position at the ½ setting?
|
Approximately 19 degrees
|
|
|
6. How many marked detented positions are available on the Flight Spoiler lever?
|
5 (0, ¼, ½, ¾, MAX)
|
|
|
7. What is the purpose of the Aileron Bungee Breakout Switch?
|
Provides automatic spoileron control transfer to the operable side in the event of a PCU runaway. Green PLT ROLL or CPLT ROLL switchlight will indicate the operable side.
|
|
|
8. What is the Horizontal Stabilizer Trim rate in manual flight?
|
High Speed (0.5 degrees per second)
|
|
|
9. The Horizontal Stabilizer trim limits are:
|
0 to 15 trim units, +2 to -13 degrees
|
|
|
10. What is the control precedence of the Stabilizer Trim?
|
Manual – rate dependent on mach airspeed
Autopilot – high rate with flap motion, low rate (0.1 degrees per second) with flaps locked AUTO Trim to compensate pitch for flap changes between 0 and 20 degrees Mach Trim – 0.03 to 0.06 degrees per second trim rate to compensate for Mach Tuck |
|
|
11. When do the Glareshield Amber Roll Select Switch/Light illuminate?
|
To indicate that roll priority selection is required, generally after ROLL DISC handle has been actuated.
|
|
|
12. What are the selectable Flap positions?
|
0, 8, 20, 30, 45 degrees
|
|
|
13. How many total flutter dampers are installed on the elevators?
|
Two on each elevator, outboard of the PCUs
|
|
|
14. How are flap actuators powered?
|
2 AC drive units
|
|
|
15. What are the extension limits of the flight spoilers?
|
0 to 50 degrees.
|
|
|
16. What caution messages apply to thrust settings with spoilers deployed?
|
SPOILERS on EICAS with above 79% N1 and spoilers extended
LOW THRUST SET when decreasing thrust below predetermined % with spoilers extended |
|
|
17. What controls are overridden when approaching a stall?
|
Continuous ignition comes on and illuminates PBA
Stick shaker and stick pusher to alert physically and force nose down, respectively |
|
|
18. How are primary flight control signals sent to the aircraft’s control surfaces?
|
Hydraulic/Cables – Ailerons, Elevator, Rudder
Hydraulic/Electronic – Spoilerons |
|
|
"Mach Tuck"
|
As speed increases, the center of lift shifts aft. Because of this, the distance between center of lift and center of gravity increases, which requires more work of the tail. Eventually, the tail cannot provide adequate downward force, which causes the nose to dip (or “tuck”). This can be dangerous, as it can cause an unrecoverable condition.

|
"PCU"
|
Power Control Unit
