AIRFRAME CPL EXAM

In level pressurized flight the outflow valve is

• Close

• Adjust to provide constant flow, and normally partially open

• Open to increase airconditioning

• Adjust to provide constant flow. And normally almost closed

A/C in level flight and if cabin pressure increase then the differential pressure

• Increase

• Decrease

• Remain the same

• Fluctuated

Main and nose wheel bays are

• Pressurised

• Unpressurised

• Conditioned

• Main wheels area pressurised, nose wheel unpressurised.

The function of frame is :

• to absorb all loads which acted to fuselage

• to form the fuselage

• the load on frames are less than load on bulkheads

• all answer at a, b and c are correct.

The CG (Center of Gravity) is :

• A point which all longitudinal, lateral, and vertical axis are crossed each other.

• A point which all moments acted from aircraft control surfaces.

• A point which aircraft weight acted

• Above answers a, b and c are correct

Which is the function of bulkheads is :

• to receive the loads from wing structure only

• to receive the bigger loads which acted on fuselage structure

• to form structure for door only

• all above answer are correct.

The rate of change of cabin pressure should be kept to minimum, this is more important in:

• In climb

• In descend

• In periods when aircond is used

• In cruise

At what point in the landing operating does normal skid control perform its function?

• anytime the wheel is rotating

• when wheel rotation indicates hydroplaning condition

• when wheel rotation deceleration indicates an impending skid

• All above are true.

what is the function of a landing gear shock strut?

• to absorb the shock loads of landing and taxiing on uneven ground.

• minimize friction on a runway.

• to get the amount of runway clearance to tire’s grip.

• to give a poor visual from cockpit.

Semi monocoque construction relies its strength on...

• the skin only

• former, bulkhead, and stringers

• former, stringers, skin

• a tubular triangular framework
