Abstract:
1. An aircraft with an emergency landing system, having a longitudinal axis running through the center of gravity and a vertical axis essentially perpendicular thereto, comprising: a trigger unit, actuatable by operating parameters of the aircraft, providing a start signal to activate the emergency landing system, a paraglider for an emergency landing phase of the aircraft, a drag parachute which is attached to the aircraft, the trigger unit being adjusted so that the drag parachute is ejected when the start signal appears, a release unit which, by way of extension lines, pulls out an attitude positioning parachute from a storage position into a braking position when the flight speed drops below a predetermined first threshold speed, a pair of first suspension lines for the attitude positioning parachute mounted on the aircraft behind, relative to the longitudinal axis, the center of gravity thereof, a pair of second suspension lines attached in front of the center of gravity of the aircraft, a positioning device which causes the braking force from the attitude positioning parachute acting on the first suspension lines to be partially transferred to the second suspension lines when the flight speed drops below a second threshold speed, and the aircraft swivels with respect to its direction of motion, and an unfolding device for the paraglider which unfolds the latter as soon as the aircraft swivels in such a way that the vertical axis essentially corresponds to the direction of pull from the attitude positioning parachute, and the speed of the aircraft drops below a predetermined maximum paraglider speed.
