A small aircraft under 900 kg MTOW wishes to land and takeoff from an airfield that is marginal in length, given the current atmospheric conditions. In regards to TODR and LDR, which is true?

LDR and TODR are both equally of concern

This cannot be determined

LDR will be the major concern

TODR is of greater concern

The combined effect of induced drag and parasite drag gives rise to total drag. The least total drag occurs

At low airspeed when parasite drag is lowest

At high airspeed when parasite drag is lowest

At the stalling speed when the speed of the relative airflow is lowest

At an intermediate airspeed when both induced and parasite drag are fairly low

Which of the following would result in a decrease in the rate of climb?

An increase in headwind component

A decrease in headwind component

A reduction in gross weight

A reduction in engine power output

Rate of climb depends on excess power (power available − power required). Reducing engine power directly reduces power available, thus reducing the rate of climb.
