Abstract
Herein provided are methods and systems for producing reverse thrust in a multi-engine propeller aircraft, comprising: obtaining, at a first engine controller of a first engine of the aircraft, a first power request for the first engine for producing reverse thrust; determining, at the first engine controller, a first blade angle for a first propeller coupled to the first engine; obtaining, at the first engine controller and from a second engine controller of a second engine of the aircraft, a second power request for the second engine and a second blade angle for a second propeller coupled to the second engine; and when the second power request is indicative of a request for producing reverse thrust and when the first and second blade angles are beyond a predetermined threshold, commanding, via the first engine controller, the first engine to produce reverse thrust based on the first power request.
