Question

1. the angle of attack at which an airplane wing stalls will 1 point

increase if the cg is moved forward.
change with an increase in gross weight.
remain the same regardless of gross weight.

Explanation:

The stall angle of attack of an airplane wing is an aerodynamic characteristic determined by the wing's airfoil shape and is not affected by the airplane's gross weight. Moving the center - of - gravity (CG) forward affects stability and control but not the stall angle of attack. The stall angle remains constant for a given airfoil regardless of weight changes as it is related to the airflow separation over the wing surface which depends on the wing's geometry.

Answer:

remain the same regardless of gross weight.
