In an aircraft flying control system employing servo-tabs, the installation of external ground locks to the main control surface.
would not prevent movement of the control column
is unnecessary since the system is irreversible and therefore the control surface cannot be displaced by the wind
would also prevent movement of the control column
A full time yaw damper system detects
band pass frequencies
all frequencies
only low frequencies
With respect to flight spoilers, they
can operate both on the ground and in flight
only operate on the ground
only operate in flight.
The bearing used in a fiber pulley is.
a ball bearing
a roller bearing
a plain bearing
When the primary stops fitted to a control run have been contacted
a clearance exists at the secondary stops
the secondary stops have been over-ridden
the secondary stops will just be in contact
Excessive wear on both sides of the control cable pulley groove is evidence of
excessive cable tension
pulley misalignment
cable misalignment
A universal protractor used to measure degrees of aileron travel should be zeroed
when the aircraft is in level flight attitude.
with the aileron in the neutral position
with the aileron in the down position
A flying control static friction check
can only be carried out during flight
demonstrates the force the pilot requires to overcome system inertia and move the controls
will demonstrate that a high force is always necessary to operate non-powered controls
What is an aileron balance cable for?.
To allow the cable to be tensioned
To correct for wing heaviness
To allow aircraft to fly hands off.
With the elevator trim wheel adjusted fully aft. (nose up), range of movement of the elevator is restricted.
would make no difference to the movement
for 'down' travel movement.
for 'up' travel movement
On the ground, spoilers/speed brakes deploy to
15°.
30°.
60°.
A horn balance on a control will
increase degree of movement at high speed
decrease degree of movement at low speed
decrease degree of movement at high speed.
In normal flight, if the control column is pulled back, a servo tab fitted to the elevator will
move up
remain in line with the elevator.
move down
In normal flight, if the control wheel is moved to the left, then the aileron on the right wing will.
decrease the angle of attack of the right hand wing
increase the angle of attack of the right hand wing
keep the angle of attack of the right wing constant
On an aircraft fitted with elevons in normal flight, if a column is moved forward, the elevons will
remain stationary.
both move down
both move up
