#17. The tendency of an aircraft to develop forces which restore it to its original condition, when disturbed from a condition of steady flight, is known as:

• Amanoeuvrability.
• Bcontrolability.
• Cstability.
• Dinstability.

#30. What happens to total drag when accelerating from C LMAX to maximum speed?

• AIncreases.
• BIncreases then decreases.
• CDecreases.
• DDecreases then increases.

#11. An aircraft has a L/D ratio of 15:1 at 50 kts in calm air. What would the L/D ratio be with a direct headwind of 25 kts?

• A30:1
• B15:1
• C25:1
• D7.5:1
