Ground effect is most likely to result in which problem?

Becoming airborne before reaching recommended takeoff speed.

What effect does high density altitude, as compared to low density altitude, have on propeller efficiency and why?

Efficiency is reduced because the propeller exerts less force at high density altitudes than at low density altitudes.

Which combination of atmospheric conditions will reduce aircraft takeoff and climb performance?

High temperature, high relative humidity, and high density altitude.

What must a pilot be aware of as a result of ground effect?

Induced drag decreases; therefore, any excess speed at the point of flare may cause considerable floating.

What effect, if any, does high humidity have on aircraft performance?

It decreases performance.
