Abstract:
The paper describes the implementation made within Airbus Flight Control of a pitch attitude protection to avoid high vertical speed in case of tail strike during go-around manoeuvres. It explains the choice of the vertical speed as a key parameter for the protection target implementation. It proposes a way to enhance the performance of the protection as well as tackle intrusiveness, by having a dedicated control loop, based on pitch attitude command.
