Landing place should be large enough, the minimum during the day is a rectangle with sides of 25×25 m for the EC 135 helicopter, and at night it’s a rectangle with sides of 50×25 m.
A flat surface without bumps, protruding rocks, etc., with a compact surface (gravel, sharp sand or dust can hurt people and damage the helicopter), if the area is dusty, you can pour some water on it.
If the difference in land level at the landing site is more than 1m at a distance of 12m, the place is too skewed.
There should be no people, vehicles, obstacles such as poles, wires of power and telephone lines, stumps, stones, animals, etc. You should remember that the power lines are both the most dangerous and the least visible for the helicopter.
In case of landing on a road, it should be on a section visible for drivers from a distance, away from bends and turns and without any obstacles.
There should be an obstacle-free landing approach with a slope of 1:6, that is, at a distance of 60 meters from the edge of the landing, obstaclea can’t be higher than 10 meters.
Side obstacles should be kept away from the edge of the airfield in the ratio 1:2, that is, at a distance of 2 meters from the edge of the landing, obstacles can’t be higher than 1 meter.
The final decision on the landing site is taken by the helicopter pilot.
