Flight Controls Flashcards
What are the primary flight controls
1) Aileron
2) Rudder
3) Elevator
What are the secondary flight controls
1) Flaps
2) Multi Function Spoilers
3) Trim: Stabilizer
How are the following controlled and actuated:
Ailerons
Elevators
Rudder
Flaps
Multi Function Spoilers
Trim
Spring Loaded Rudder Booster (SLRB)
Stick Pusher
1) Primary Flight Controls are Mechanically Controlled and actuated
2) Flaps, Multi Function Spoilers, Trim, SLRB and Pusher are all electrically controlled
3) Flaps and Trim are Mechanically Actuated
4) Spoilers, SLRB and Pusher are Hydraulically Actuated.
What items are disabled when the quick disconnect button is pressed and held
1) Autopilot
2) Yaw Dampner
3) Trim
4) Stick Pusher
What items remain disabled when the quick disconnect button is pressed and held
1) AP
2) YD
What is the flap position in degrees for each of the following flap lever positions?
Flaps 1: 8
Flaps 2: 26
Flaps 3: 26
FULL: 35
Which functions are controlled through the Flight Control Electronics Units 1 and 2 (FCE 1 and 2)
FCE 1: Flaps, Backup Trim
FCE 2: Manual Trim, Automatic Trim, Speed Brake Configuration Trim and Multi Function Spoilers.
With regard to design, how is pitch trim force accomplished?
An electric motor driven actuator moves the horizontal stabilizer angle of incidence.
What is the max duration of trim (all 3 axes) prior to cutout
3 seconds
Which axis of trim generates an aural alert when command exceeds 3 seconds
Pitch Trim only
How are pitch trim commands normally issued with the AP disengaged
The spring loaded control wheel pitch trim switch commands the Flight Control Electronics (FCE 2), which in turn commands the pitch trim actuator (PTA)
How are pitch trim commands normally issued with the AP engaged
The AFCS commands the FCE2 which in turn commands the PTA
How are pitch trim commands issued with the PITCH BKP MODE switch in the BKP position
The spring loaded PITCH BKP DN/UP trim switch commands the FCE1. which in turn commands the PTA
Is the AP available with the PITCH BKP MODE switch in the BKP position
No
How are roll trim commands issued
The spring loaded ROLL trim switch directly commands the Trim Actuator Controller (TAC)
How are yaw trim commands issued
The spring loaded YAW trim switch directly commands the Trim Actuator Controller (TAC)
Which axis of trim commands are issued through the Flight Control Electronics (FCE)
Pitch only -
1) Manual (AP off) and Automatic (AP on) is through FCE2
2) Backup through FCE 1
How does the automatic pitch trim (AP On) avoid the 3 second cutout and alert
Automatic pitch trim limits its own continuous input to less than 3 seconds
Is pitch trim mode rate a function of airspeed in both Normal and Backup modes?
Yes, in both Normal and Backup the higher the airspeed, the lower the rate and vice versa
Are roll and ya trim rate a function of airspeed
No, they operate at a fixed rate
Describe the function of the ventral rudder under the following conditions
Weight on Wheels below 60 KIAS
Above 60 KIAS, YD off
YD Engaged
Weight on Wheels below 60 KIAS: Centered
Above 60 KIAS, YD off: YD Mode
YD Engaged: Streamlining mode
What are the 3 functions of the Multi Function Spoilers
1) Roll Spoiler
2) Ground Spoiler
3) Speed Brake
What criteria must be met for the Multi Function Spoilers to deploy or remain deployed with the SPEED BRAKE switch in the OPEN position
1) Flaps Retracted
2) Thrust Lever Angle less than 38 deg (MAX CRZ)
3) Airspeed less than 125 KIAS
What criteria must be met for the Ground Spoilers to arm
Wheel speed of 50 knots OR Weight off Wheels 10 seconds
What criteria must be met for the ground spoilers to deploy
1) Both Thrust Levers Idle
2) Weight on Wheels
3) Wheel speed greater than 50 knots
Below what wheel speed are the Ground Spoilers dis-armed
45 knots
What is the purpose of the Ventral Rudder
To act as a YD when YD is off.
Will the spoiler panels remain deployed if any WOW returns to air after touchdown (bounce landing)
Yes, unless the aircraft returns to air for more than 10 secs
