Flight performance and planning

7.5 Climbing

While climbing, flaps are usually not used.

Full throttle and a rich mixture are used to cool the engine.

The smaller the TOW, the better the climb characteristics of the aircraft will be,
and both range and endurance will be improved.

The lower the temperature, the better the climb characteristics. The lower the

altitude, the better the climb characteristics.

The only case where you benefit from high altitude and low air resistance is when

you look at the aircraft's range. Normally, you will also be able to get a higher

cruising speed at a given performance, the higher you fly.

With regard to range, you must take into account whether there is a headwind or
tailwind. If there is a headwind, the speed must be increased, and if there is a

tailwind, the speed can be reduced slightly.

The same applies when talking about glide speed to achieve the best glide

distance in the event of an engine stop.
