Limitations: DGCA Technical General questions

Question 1

What is the purpose of fitting the engines to an aircraft using wing mounted pylons?

Accepted Answer

The wing structure can be lighter because the engine acts as a mass balance and also relieves wing bending stress.

Answer

They give increased ground clearance in roll.

Answer

They give improved longitudinal mass distribution.

Answer

They enable a longer undercarriage to be used which gives an optimum pitch attitude for take-off and landing.

Question 2

The speed VNE is:

Accepted Answer

The maximum airspeed at which an aircraft may be flown.

Answer

The airspeed which must not be exceeded except in a dive.

Answer

The maximum airspeed at which manoeuvres approaching the stall may be carried out.

Answer

The maximum speed, above which flaps should not be extended.

Question 3

Maximum structural cruising speed VNO is the maximum speed at which an aeroplane can be operated during:

Accepted Answer

Normal operations.

Answer

Abrupt manoeuvres.

Answer

Flight in smooth air.

Answer

Flight in rough air.

Question 4

The maximum allowable airspeed with flaps extended (VFE) is lower than cruising speed because:

Accepted Answer

The additional lift and drag created would overload the wing and flap structure at higher speeds.

Answer

They are used only when preparing to land.

Answer

Flaps will stall if they are deployed at too high an airspeed.

Answer

Too much drag is induced.

Question 5

If flutter is experienced during flight, the preferable action would be:

Accepted Answer

Reduce speed immediately by closing the throttles, but avoid rapid changes in attitude and/or configuration.

Answer

Immediately increase speed beyond VMO/MMO, by sacrificing altitude if necessary.

Answer

Immediately close the throttles, deploy the speed brakes and bank the aircraft.

Answer

Rapidly pitch-up to slow the aircraft as quickly as possible.
