Body cambered and tail down to reduce speed increases lift and the nose-down pitching moment. To trim wings move forward to displace centre of pressure ahead of centre of gravity. Airflow begins to separate near wing trailing edges as speed is reduced causing soft feathers to ruffle upwards turbulating the boundary layer delaying further separation and stall. Alula bastard wing acts as a slat by extending at the leading edge inboard of the primary pinion feathers to delay stall by keeping flow attached. Landing gear coming down to increase drag before rolling wings half folded into an evasive dive. DMT EttHnger via Shell Aviation News UK
