Across
  1. 2. Rotation about the lateral axis.
  2. 4. Controls the aircraft in pitch.
  3. 6. Mass balancing prevents this.
  4. 7. Rotation about the normal axis.
  5. 8. brakes Aerodynamic brakes.
  6. 9. A span wise gap in a wing to maintain boundary layer.
  7. 11. balance An aerodynamic balance projecting forward of a control surface.
  8. 12. Controls movement about the longitudinal axis.
  9. 15. Used on large aircraft to reduce stability.
  10. 17. Lowering the flaps increases this.
Down
  1. 1. Creates lateral stability.
  2. 3. Axis The axis through the centre of the fuselage from nose to tail.
  3. 5. Can be a brake or a flight control.
  4. 6. Hinged surfaces at the rear of the wing designed to change its camber.
  5. 10. stability The ability of an aircraft to return to smooth flight once disturbed.
  6. 13. Rotation of an aircraft around the longitudinal axis.
  7. 14. moveable surfaces on the leading edge designed to increase lift at high angles of attack.
  8. 16. Controls yaw.
