Across
  1. 2. must be increased to maintain the original airspeed and altitude while turning
  2. 4. of Attack is the angle between chord and relative airflow
  3. 6. they are designed to increase the lift of the wing at lower speeds
  4. 7. Located in the leading edge of the wing & is a fixed duct
  5. 8. is the all up weight (AUW) of the aircraft divided by the wing area
  6. 9. It occurs when the angle of attack becomes so great that the energy in the air flowing over the wing can no longer pull air down to the surface
Down
  1. 1. increases with increase in lift
  2. 2. The Lift on the wings during the _______ is greater than the Lift which the wings have to supply during straight flight
  3. 3. it is a movable slot
  4. 5. _______ increases with increasing the angle of attack
  5. 7. it is the minimum speed the aircraft can fly without stalling
