Default RE: my plane is ballooning


ORIGINAL: Hossfly

WRONG! The wing will fly at an angle-of-attack that it is forced into by the stab., if the pilot places the elevator in a position to do so. If the weight and airspeed are producing the proper lift for straight flight then lift equals gravity. A dragging tail will always be applying force against the wing to make it move somewhwere else.

Just go watch a jet airliner on final approach. The angle of the fuselage will be high, yet the airplane is on a descending path towards the runway, due to the high AOA (angle of attack) of the wing required for the relative slow speed. The elevator of the machine may appear to be inline with the stab, but that is because the stab, in most machines is a slab, and trims to an AOA that holds the wing in the high AOA. No big secret.
Well it cannot keep that angle of attack at full speed and level flight, that was my point...
