ATA 27 Flight Controls Flashcards
What is the maximum aileron deflection?
19.8° downwards from zero
23.2° upwards from zero
(+2° & -1° for both)
To which channel is the autopilot servo linked?
The Right aileron channel
What happens when the main roll trim switches are used?
Electrical power is applied to the left aileron trim actuator
In how many points are the rudder hinged to the fin?
2
What is the maximum rudder deflection below 150 knots
55°
What is the maximum rudder deflection between 150-200 knots
30°
What is the maximum rudder deflection over 200 knots?
12,6°
What is the neutral position of the rudder?
5° bias angle to the right of the centreline
How tall is the rudder?
11 ft
From where do the rudder limiter get the analogue signal?
From the Air Data Computer (ADC)
What is the maximum deflection of the elevators?
18° downwards from zero
22° upwards from zero
Elevator trim tab deflection?
+/- 6° from neutral
Which trim actuator do the pitch trim synchroniser control?
The RH. The pitch trim synchroniser compares the left trim actuators position and synchronise the right one
