How is flutter and vibration eliminated on a control surface?
Hydraulic damping or static balancing
When do spoilers assist the flap system?
As ground spoilers - lift dump
What component maintains the cable temperature over varying temperatures?
Cable tension regulator
Movement around the lateral axis will do what to the aircraft
Change the angle of attack
What effect will there be if you select speed brakes out in a turn?
Both sets of spoilers will extend by a set amount
What prevents aerodynamic loads from pushing screwjack operated flaps back up?
A no-back brake
How is over run of a trimmable horizontal stabiliser prevents?
Switches and mechanical stops
What will occur at the control column if aileron trim is activated?
Moves the control column in the same direction
What is the meaning of the term turn coordination?
Control surfaces act in conjunction with eachother
What occurs if only one side of the flaps deploy?
Flap extension is automatically stopped
How is airflow maintained at high angles of attack of the aerofoil?
Using slotted slats
What is the result of the left and right wing ailerons both deflecting downwards together?
Droop assist for the flaps
If the flaps and slats are deployed, what is happening to the air loads on the aircraft?
Increase in lift and drag
Which flight controls could activate a take off warning?
