5.3.1 Endurance
The power requirement of propeller in the dependence of the airspeed has the
quadrate running. The power consumption and also the fuel consumption increases
with square of the airspeed. The flight altitude is another factor, which effects the
fuel consumption, because the performance drop with increasing flight altitude. The
minimum fuel consumption is at lift-over-drag maximum speed, which is 115 km/h.
The minimum fuel consumption is at lift-over-drag maximum speed, which is 115
km/h. The good compromise for effective cruising performance is the airspeed range
from 180 to 220 km/h.
