CPL Acft Tech - Airframe & Undercarriage

Gust loads are caused by...

• a sudden change in velocity of the air

• vigorous movements of the control column in response to turbulence

• a control surface deflecting and imparting a force on the wing

• the aircraft being manoeuvered such that g forces increase

"Strain" is...

• the measure of the deformation of a structure

• any load placed on a structure

• the ability of a structure to impart a load on a structure

• The SI unit for an impact force on a structure

What force is being exhibited here?

• Tensile

• Tension

• Torsion

• Compression

"Shear loading" describes the force produced when...

• compression and tension happen at the same time

• torsion is opposed by weight

• a bending load causes a stress fracture

• one object tries to slide over another

The most common type of airframe construction is...

• semi-monocoque

• truss

• stressed frame

• monocoque

In the picture, which letter is pointing to a Longeron?

• A

• B

• C

• D

A "sternpost" can be found in...

• vertical fins

• wings

• ailerons

• elevators

Light aircraft controls are generally actuated by

• cables

• hydraulics

• mass balances

• aerodynamic balances

In an oleo-pneumatic strut...

• the oil provides the shock absorption

• the oil provides a damping medium

• the air is provided for cooling of the oil

• the air is forced into the oil chamber to provide a cushioning

The maximum extension on the nose oleo of a light aircraft should be approximately

• 12cm

• 10cm

• 7cm

• 2cm
