35. Thrust, Stability, & Center of Gravity

Question 1

Unlike an automobile, your airplane can only be loaded to a certain weight. If it is loaded beyond the maximum allowable weight it will experience:

Answer 1

1. Higher stall speeds and longer takeoff distance
2. Lower rate of climb
3. Longer landing roll.

Question 2

If an airplane is loaded with the CG forward of the allowable range:

Answer 2

The pilot needs to use more back pressure on the elevator to hold the nose up.

Question 3

Lateral or roll stability is normally achieved by:

Answer 3

The upward pitch of the wings, called dihedral.

Question 4

An airplane is designed for stability. Stability can be described:

Answer 4

An airplane is stable if it will return to its original flight attitude after it has been disturbed.

Question 5

In straight-and-level flight, if thrust exceeds drag then:

Answer 5

Speed increases.

Question 6

For directional stability, an airplane tends to weathervane back to a stable position due to:

Answer 6

More fuselage aft of its CG.

Question 7

If the loaded center of gravity is aft of the allowable range, pitch stability:

Answer 7

Is reduced.

Question 8

In steady unaccelerated flight:

Answer 8

Lift equals weight.

Question 9

The total weight of an airplane is comprised of:

Answer 9

1. Airplane
2. Crew and passengers
3. Fuel
4. Baggage.
