Consisting of a flap-type aerodynamic surface on the wing(s) (2) above the fuselage (1) of an aircraft with control surfaces (5) of the wing (2), the length of the device in the wing span direction being greater than or equal to the mid-chord of the flap, and comprising a thrust propeller engine (4), converting it into a propulsive flapper (3).

The embodiments of the Parachute Landing Assistant are comprised of a battery pack, a power switch, an LED indicator light; an audio jack; a microcontroller; and a ground proximity sensor. The battery pack is comprised of a power storage means such as alkaline, lithium ion, or other types of battery system. The power switch allows the parachutist to enable or disable the operation of Parachute Landing Assistant. The LED indicator light is comprised of an LED that informs the parachutist as to whether the Parachute Landing Assistant operation is enabled or disabled. The audio jack is comprised of a standard , , or 3/32 mono audio or stereo audio receptacle that accepts the analogous audio plug. The microcontroller controls all the other components of the Parachute Landing Assistant. The ground proximity sensor senses the distance from the ground of the parachutist.
