In the diagram all the small forces of gravity acting on the ruler balance about a point called?
The centre of gravity
Static centre
The dynamic centre
The centre of pressure
Lift is obtained from almost all parts of the wing but not equally from every part. About how much is obtained from the top surface of an aircraft wing such as a Chipmunk?
Up to 33%
Up to 80%
Up to 50%
Up to 25%
As air passes over the top surface of a wing in normal flight, its speed will:
Reduce slightly
Increase
Reduce considerably
Remain Constant
Where is the greatest amount of lift normally generated on an aerofoil?
Trailing edge
Leading edge
Top surface
Bottom surface
Where is the airflow fastest in this diagram of an aerofoil in an airflow?
V
O
E
L
To obtain the maximum drag from an aircraft's flaps, they should be set to?
40 degrees
30 degrees
90 degrees
10 degrees
Aircraft movements such as pitching, rolling and yawing are always described in relation to the?
Ground
Horizon
Pilot
Airflow
Which axis runs from nose to tail in an aircraft?
Normal
Bilateral
Lateral
Longitudinal
On this cross-section of a wing, which arrow points to a flap?
U
R
T
S
In the diagram, what has happened to the air pressure at Point B?
It is greater than at point C
It is greater than at point A
It is lower than at point C
It is the same as at point C
What is the purpose of the trimming tabs on flying controls?
To improve the manoeuvrability of the aircraft
To cancel out the unwanted forces on the pilots control
To increase the approach angle during landing
To reduce the take off run of an overloaded aircraft
Glider A is travelling downwind and glider B is travelling into wind. The indicated airspeed, angle of attack and gliding angle relative to the airflow are the same for both gliders. Therefore:
Glider B will travel further over ground than Glider A
Glider A will travel further over ground than Glider B
Both Gliders should travel the same distance
The Glider travelling the furthest cannot be determined
When a glider pilot operates the airbrakes what is the effect?
Lift is reduced and drag is increased
Lift is reduced and drag is reduced
Lift is increased and drag is increased
Lift is increased and drag is reduced
When would a glider pilot use airbrakes?
When being winch-launched
When wanting to turn
When approaching to land
When wanting to climb
The flatter the gliding angle of a glider, the further the glider will travel over the ground.
This angle is least when the ratio of lift to drag (the 'lift/drag' ratio) is:
At its highest
At its lowest
Equal to zero
Equal to one
