1.	What are the major sources of change in the aerodynamic forces and moments applied to an aircraft?(a) Angle of attack of the wing and the angle of attack(b) Angle of attack of the wing and the angle of attack of the vertical tail(c) Angle of attack of the wing and the angle of incidence(d) Angle of incidence and the angle of attack of the vertical tailI had been asked this question in exam.My doubt stems from Flight Dynamics topic in section Flight Dynamics and Control of Aircraft Maintenance
Answer» Right CHOICE is (b) Angle of attack of the wing and the angle of attack of the VERTICAL tail For explanation: The two major sources of change in the AERODYNAMIC FORCES and moments applied to an aircraft are the angle of attack of the wing and the angle of attack of the vertical tail. The two angles are important to maintain the center of gravity of an aircraft.
