5. stall

6. During an eract spin recovery? )The control stick is pulled to the most aft position b)The ailerons are held in the neutral position The control stick is moved sideways,against the AOB d)The control stick is moved sideways, in the direction of the AOB

7. During an eract spin recovery? a)The control stick is pulled to the most aft position b)The ailerons are held in the neutral position C)The control stick is moved sideways,against the AOB d)The control stick is moved sideways,in the direction of the AOB

8. ANSWERS: To recover from an erect spin x It is necessary to stop yawing,reduce AOA & increase the airspeed by pushing the stick forward to push the ose down No aileron input to be used as it will increase the AOA OF ONE WING & it might cause rolling spin To avoid this the stick must be held roll neural

9. gf the following statement about the spin is c rrect? a)Every airplane must be designed such that it can never enter a spin b)During spin recovery the ailerons must be kept in the neutral positions c)An airplane is prone to spin when the stall starts at the wing root d)In the spin,airspeed continuosly increases

10. Which of the following statement about the spin is correct? the following statement about the spin ls correct? a)Every airplane must be designed such that it can never enter a spin b During spin recovery the ailerons must be kept in the neutral positions c)An airplane is prone to spin when the stall starts at the wing root d)In the spin,airspeed continuosly increases

11. Which type of stall has the largest associated AOA? a)Low speed stall b)Deep stall c)Shock stall d)Accelerated stall

12. ANSWERS: The term deep stall' refers to a situation in which aircraft pitches nose up in the stall.This upward pitching coupled with loss of height due to loss of lift from the stalled wings,increases AOA causing the aircraft to go deeper into the stall.Thus deep stall is the stall which is associated with the largest AOA

13. ANSWERS: When extremely heavy rains lands on an aircraft it will form thick rippling streams over its surfaces.The airflow will then flow over these streams of water instead of the surface of aircraft.This will change the shape of airfoil & roughen the effective surface.This will decrease Cl max & increase the drag
