SYSTEM TO ASSIST FORMATION FLIGHT OF AIRCRAFT

A system for aiding formation flying of a follower aircraft with respect to a wake vortex from a leader aircraft comprises a controller and at least one accelerometer installed on the follower aircraft. The controller receives acceleration measurements performed by the at least one accelerometer and processes the measurements to obtain a value representative of vibrations generated by the wake vortex from the leader aircraft. The controller compares the value with at least one predetermined threshold representative of excessive vibrations with regard to location of the at least one accelerometer on the follower aircraft. One or more notifications, such as alerts, are generated based on the result of the comparison. It is easier to position the follower aircraft in formation flying to benefit from a rising airflow phenomenon brought about by the wake vortex from the leader aircraft.
