Across 1. The rear of the aircraft 5. System for maintaining conditions of pressure within an airplane closer to sea level conditions than to the "thin" atmosphere outside while at a high altitude. 7. That part of an airplane which extends out from the fuselage and which provides the "lift". 8. Toward the inside, nearest to the centre of the fuselage. 10. Wind blowing against the forward motion of the aircraft and slowing its ground speed. 13. Paved surface on the “airside” (restricted area) of the airport on which aircraft are parked. 14. Upright piece on tail which controls the yaw, or turning of the airplane from right to left. 15. An instrument in the flight deck used to measure altitude. 17. An internal dividing wall inside the aircraft cabin. 18. Control surfaces hinged on the trailing edge of the stabilizer (horizontal assembly of the tail section) which controls the pitch or the movement of the nose up or down. 21. Washroom on the aircraft. 23. To operate an airplane under its own power, on land other than in actual takeoff and landing. 25. A series of flights assigned to a Flight Attendant each month. 26. A hinged appendage located on the trailing edge of each wingtip which controls the rolling or banking movements of the aircraft. 27. Wind blowing from behind the aircraft and increasing its ground speed. 28. A paved surface used by aircraft for the purpose of taking- off and landing.

Down 2. An auxiliary airfoil hinged to the trailing edge of each wing. Its purpose is to increase lift at a slower airspeed and improve pilot to ground visibility on landing. 3. International distress signal 4. The pattern of seats, cargo partitions and other items on a particular airplane or flight. 6. The right side in relation to the forward (nose) of the aircraft. 9. The left side in relation to the forward (nose) of the aircraft. 11. A retarding force which is created by the total resistance of the air to the aircraft moving through it. 12. The positioning of a crew and at a non-base location for the performance of a flight. 16. Body of the airplane to which the wings and tail are attached. 19. Hydraulically-actuated plates which rise on the upper surface of the wing. 20. The height above the ground at which more than half the sky is covered by clouds, smoke or dust; distance from the ground to the lower base of the lowest cloud cover. 22. In a position closer or closest to either of the wing tips of an airplane. 24. The aircraft kitchen. The place where all supplies and equipment necessary for the in-flight service are located.
