ABSTRACT:
The present invention relates to an emergency landing auxiliary apparatus of an aircraft using a parachute, whereby a rapid accident crash of an aircraft can be avoided through releasing the chute set inside an apparatus accepting room 11 and the landing distance of the aircraft can be reduced in case of an emergency landing. Therefore, the present invention is effective in decreasing a possible loss of lives and the damage of the aircraft itself. When a relay switch is pushed, the DC current produced in a DC generator is applied to a timer via an overvoltage overcurrent preventer so as to operate the timer in several seconds and drive a speed reduction motor, the worm turns to rotate the worm gear in 90-degree arc, so that the leg of the cover is in a ready state not to be released out of the 90-degree arc turned cam,
