Why

Module 8. Basic aerodynamics

On an aircraft with an all-moving tailplane, pitch up is caused by

please explain

Module 8. Basic aerodynamics

Stall commencing at the root is preferred because

  • it provides the pilot with a warning of complete loss of lift.
  • it provides a clear aerodynamic warning of the approaching loss of aileron effectiveness.
  • it will cause the aircraft to pitch nose up before the outer wing sections lose their lift.
Afshinarabi asking:

Stall commencing at the root is preferred because it provides the clear aerodynamic warning of the approaching loss of aileron effectiveness .Warning signs: When the wing root stalls first, the disrupted and turbulent airflow causes buffeting or a shaking of the aircraft's elevators and control stick, alerting the pilot to the impending stall before total lift is lost .Control retention: Because the stall starts inboard, the wingtips continue to fly smoothly. Since ailerons are typically located on the outer portions of the wing, the pilot maintains roll control to keep the wings level and safely recover
