Question 1) What is a semi-monocoque structure?

One consisting of a heavy duty framework covered by doped fabric

One consisting of a heavy duty framework covered by skin, usually aluminum

One consisting of a light framework covered by a doped fabric

One consisting of a light framework covered by skin, usually aluminum

Correct! Wrong!

Aircraft skin takes almost all of the load, with the light framework taking the remainder and providing an alternate load path in the event the skin becomes damaged.

Question 2) What are the wing structure elements which take up vertical bending loads?

Ribs

Spars

Skin

Longerons

Correct! Wrong!

Wings generally have more than one internal spar. They run from the fuselage to the wingtip and manage the upward and downward motion of the wing.

Question 3) What is the ideal ratio of fuel to air by weight?

1:2

1:20

1:12

1:22

Correct! Wrong!

1 part fuel to 12 parts air is the ideal ratio. 1:8 would be a rich mixture and 1:20 would be considered a lean mixture.

Question 4) What would happen if the primer is not locked?

A rich cut may occur at low power settings

The risk of detonation is increased

Too little fuel may be drawn into the cylinders

A lean cut may occur at high power settings

Correct! Wrong!

If the primer is not locked then the engine could be receiving extra fuel into the induction chamber which could result in a rich cut at low power settings when not as much fuel is required. It is also a fire hazard.
