Obstacle clearances for take-off
Obstacle clearance for take-off requires that no obstacles appear in a zone between a safety

the safety angle over a distance of 100 m (this is typically called the Ground Safety Zone
(GSZ)).
This zone extends over an area between the launch direction and an offset of 45º to the right
