Flight Controls Flashcards
What are the primary flight controls?
-Aileron
-Elevator
-Rudder
What are the secondary flight controls?
-Flaps
-Multi-function spoilers
-Trim: Stabilizer
Flap position in degrees for each flap setting
Flaps 1: 8 deg
Flaps 2: 26 deg
Flaps 3: 26 deg
Flaps full: 35 deg
Which functions are controlled through the following units?
-Flight Control Electronics (FCE) 1:
-Flight Control Electronics (FCE) 2:
FCE1-Flaps, Backup Trim
FCE2-Manual Trim, Automatic Trim, Speed Brake Configuration Trim, Multi-Function Spoilers
How is pitch trim force accomplished?
An electric motor driven actuator moves the horizontal stabilizer angle of incidence.
When does the trim cutout on all axis?
After 3 seconds
Which trim will sound an aural alert after 3 seconds of holding it?
Pitch Trim only
How are pitch trim commands normally issued with the autopilot 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 autopilot engaged?
The Automated Flight Control System commands the Flight Control Electronics (FCE)2, which in turn commands the Pitch Trim Actuator.
How are pitch trim commands issued with PITCH BKP MODE switch in the BKP position?
The spring-loaded PITCH BKP DN/UP trim switch commands the Flight Control Electronics (FCE) 1, which in turn commands the Pitch Trim Actuator
Is the autopilot available with the PITCH BKP MODE in the BKP position?
No
How are roll trim commands issued?
The spring-loaded ROLL trim switch commands the Trim Actuator Controller
How are yaw trim commands issued?
The spring-loaded YAW trim switch commands the Trim Actuator Controller
Which axis of trim commands are issued through the Flight Control Electronics? (FCE)
Pitch only- Manual (AP off) and Automatic (AP on) through FCE 2, Backup through FCE 1
IS pitch trim motion rate a function of airspeed in both Normal and Backup modes?
Yes, in both Normal and Backup, the higher the airspeed- the lower the trim rate, and vice versa.
Are roll and yaw trim rate a function of airspeed?
No, roll and yaw trim operate at a fixed rate
What are the 3 functions of the Multi-Function Spoilers?
-Roll Spoiler
-Ground Spoiler
-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?
-Flaps Retracted
-Thrust Lever Angle < 38 deg (MAX CRZ)
-Airspeed > 125 knots
What criteria must be met for the Ground Spoilers to arm with weight on wheels?
Wheel speed above 50kts
What criteria must be met for the Ground Spoilers to arm with weight off wheels?
Weight off wheels > 10 seconds
When armed, what criteria must be met for the Ground Spoilers to deploy?
-Both thrust levers less than 24 deg (halfway between IDLE and CRZ)
-Weight on wheels OR wheel speed Greater than 50 kts
Below what wheel speed are the Ground Spoilers disarmed?
45kts
Do the Ground Spoilers retract in the event of a bouncing touchdown?
No, the Ground Spoilers remain deployed for 10 seconds following weight off wheels, unless the thrust levers are advanced above 24 deg.
Do the Ground Spoilers retract automatically the event of a touch-and-go maneuver?
yes, the panels retract if any thrust lever is advanced above 24 deg.
What is the cockpit indication of Speed Brake or Ground Spoiler function?
SPDBRK or GND SPLR annunciation in SPOILER box (left portion of MFD)
What criteria must be met for Spring loaded Rudder Booster (SLRB) activation?
FADEC detects thrust asymmetry
Which component commands the Spring Loaded Rudder Booster (SLRB) activation?
FADEC
Describe the function of the Spring Loaded Rudder Booster (SLRB)
When activated, a hydraulic actuator extends 2 springs, providing force to assist the pilot in moving the rudder to its limit.
What is the electrical power source for the rudder lock?
Hot Bus 2
