An aeroplane flying with an airspeed of 200 kt and CL is equal to 0.6. The pilot is requested to increase speed to 250 kt by the ATC. The new CL is…
Select the answer:Select the answer
1 correct answer
A.
0.47
B.
0.38
C.
0.2
D.
0.40
The lift coefficient (CL) is directly proportional to the airspeed of the aeroplane. Therefore, when the pilot increases the airspeed from 200 kt to 250 kt, the new CL decreases accordingly. In this case, with the new airspeed of 250 kt, the new CL is calculated to be 0.38.

An aeroplane has a stall speed of 100 kt. When the aeroplane is flying a level co-ordinated turn with a load factor of 1.5, the aeroplane will stall in this turn at:
Select the answer:Select the answer
1 correct answer
A.
150 kt.
B.
122 kt.
C.
82 kt.
D.
141 kt.
In a level co-ordinated turn with a load factor of 1.5, the stall speed will increase by the square root of the load factor. Therefore, the aeroplane will stall in this turn at approximately 122 kt.

Select the answer:Select the answer
1 correct answer
A.
IAS increases.
B.
TAS decreases.
C.
lift coefficient increases.
D.
lift coefficient decreases.
When climbing above the tropopause at constant Mach number and aeroplane mass, the lift coefficient increases due to the reduction in air density which requires higher lift to maintain level flight.

In twin engine aeroplanes with propellers turning clockwise as seen from behind:
Select the answer:Select the answer
1 correct answer
A.
the left engine is the critical engine.
B.
the ‘minimum control speed’ is determined by the failure of the right engine.
C.
the left engine produces a higher yaw moment if the right engine fails than vice versa.
D.
the right engine is the critical engine.
In twin engine aeroplanes with propellers turning clockwise as seen from behind, the left engine is considered the critical engine because it produces more yawing moment in the event of an engine failure.
