Question 1

Increasing altitude in a propeller powered aircraft:
a. Shifts the power required curve to the right, lowering the tangent, and improving the airframe consideration for range.
b. Shift the power required curve up to the right, keeping the tangent in the same location, and therefore not changing the airframe consideration for range.
c. Shifts the power required curve up to the left, raising the tangent, and improving the airframe consideration for range.
d. Shifts the power required curve up to the left, raising the tangent, and decreasing the airframe consideration for range.

Answer 1

Shift the power required curve up to the right, keeping the tangent in the same location, and therefore not changing the airframe consideration for range.

Question 2

The maximum angle of climb requires:

a. The maximum ratio of excess thrust to weight.
b. The maximum ratio of excess power to weight.
c. The maximum thrust required.
d. The sine of the climb angle to be a minimum.

Answer 2

The maximum ratio of excess thrust to weight.

Question 3

The aircraft’s indicated stalling speed is:

a. Achieved at the maximum lift coefficient.
b. Achieved at the highest angle of attack where NO turbulent airflow exists.
c. Significantly greater at high altitudes due to lower air density.
d. Significantly slower at high altitudes due to lower air temperatures

Answer 3

Achieved at max lift coefficient

Question 4

How will increasing the altitude of a jet aircraft affect its range performance curve?

It will shift the thrust required curve to the right, improving the airframe consideration for range by lowering the tangent to the curve
It will shift the thrust required curve up to the right, improving the airframe consideration for range by lowering the tangent to the curve
It will shift the thrust required curve to the right, improving the engine consideration for range by lowering the tangent to the curve
It will shift the thrust required curve to the left, raising the tangent to the curve, and hurting the airframe consideration for range

Answer 4

It will shift the thrust required curve up to the right, improving the airframe consideration for range by lowering the tangent to the curve
