FOLV 1 Angle of Attack (AoA)

The AoA system is designed to easily inform the pilot of the wings angle to the relative airflow it is flying through.

While most pilots are trained to know that the wings stall at a certain speed, this is not the truth. What really decides when a wing stalls, is its angle to the relative airflow it is going through.

The sensor of the FOLV 1 follows the relative airflow and continuously measures the angle relative to the wing with 0.1 degrees precision.

In cruise attitude the sensors weather vane and the wings chord line will be close to parallel. The display will then display a green LED to illustrate that there is sufficient lift for sustained flight.

An instrument that measures the Angle of Attack (AOA) can significantly increase the safety of the pilot and the passengers, especially under situations where the risk of stalling is high (such as a landing).

Our AOA will be available in our online store shortly. Contact us to order in the meantime. 

The Angle of Attack (AoA):

is the angle between the aerofoil chord line and the free stream velocity vector. Stall occurs when the wing angle of attack has exceeded a critical value called stall angle of attack or critical angle of attack, and the air ow has detached from the aerofoil, thus ceasing to provide sufficient lift to balance the airplane weight.
