Annex 4 - 2.C8 DECK LANDING
The objective is for the aircraft to land in a deck 100 metres long by 25 metres wide.
This task proves the short landing capability that is fundamental to the performance characteristics of a Microlight by demonstrating that the aircraft can land in 100 metres in still air at sea level. Deck length shall be adjusted according to the airfield elevation (S10 4.31.5). The width of the deck may be decreased to be adjusted to the width of the existing runway (S10 4.31.5). Where other local conditions, such as slope of the runway, will make a significant difference to landing runs the length of the deck may be adjusted accordingly.
Provided of an approximately linear characteristic of the ratio between acceleration and needed takeoff distance in the phase short before takeoff, the deck extension for short-takeoff and landings has to be 25 meters (rounded down).
Calculation: 100m * 83 km/h / 65km/h = 127,69m
