relieve excess pressures and remove hazardous or foul smelling gases.

If an aircraft major structural element is replaced after a fixed number of flight cycles, this is known as

safe-life.

If an aircraft structure uses multiple load paths to ensure integrity, this design philosophy is known as

fail safe.

Damage tolerant structure is a structure where aeroplane damage is detected and repaired before

the strength is below a minimum level.

Exhaust gas deposits forming on areas of aircraft structure

can cause corrosion and must be removed with special solvents as recommended by the aircraft manufacturer.

convection method.

The component that act as a reservoir for the refrigerant is

receiver/drier.

The actual height above sea level at which an aircraft is flying is called

aircraft altitude

The aircraft fuselage relies largely on the strength of the skin or covering to carry the primary stress is called

monocoque fuselage.

The colour used to identify the secondary structures is

Yellow or hatched.

The location identification system is used to pinpoint

the various locations in an aeroplane.

Pressurized aircraft cabin is affected by

Hoop stress.

The type of structure which carries only air or inertial loads is

tertiary
