7.4 Landing distances
Landing data is given in the aircraft handbook.
Just as the climb to 50 feet is calculated at takeoff, the distance from the aircraft
at an altitude of 50 feet to the point of coming to rest on the runway is calculated
when landing. The distance the aircraft travels on the ground is called the landing
roll.
7.4.1 Calculation of landing distance
Factors that affect the landing distance:
- approach speed Factors affecting landing roll:
- aircraft weight - sink rate
- wind - aircraft weight
- density altitude - wind
- pilot technique - pilot technique
- use of flaps - runway surface and slope
- runway surface and slope
7.4.1.1 Pilot technique
When talking about the pilot's abilities, it is whether he is able to use the
procedures described accurately. In connection with landing, there are factors
such as wind conditions and approach speed that increase the requirement for
safety factors.
Here we use a factor of 40% instead of the 25%, because it turns out that it is
landings that cause the biggest problems and are responsible for most accidents.
