1. PROCEDURE A pre-planned instrument flight rule (IFR) departure route published for pilot use to provide obstacle clearance and a transition from the terminal to the en route environment.
3. The main body of an aircraft.
5. Any area of land used for the arrival, departure, and surface movement of aircraft.
6. Pertaining to the axis running from nose to tail of an aircraft.
9. NUMBER A dimensionless quantity representing the ratio of the true airspeed to the speed of sound.
14. A type of material, often carbon fiber, used in modern aircraft construction for its strength and light weight.
15. The process of removing ice, snow, or frost from an aircraft's surface.
17. The condition of an aircraft, its components, and materials to operate safely.
18. TUBE A probe that measures airspeed by sensing ram air pressure.
20. The condition of an airfoil when the angle of attack increases beyond a certain point such that the lift begins to decrease.
21. A person responsible for flight planning and operational control, often sharing responsibility with the pilot-in-command.
24. A sudden change in wind speed and/or direction over a short distance, a significant hazard for aircraft.
26. REVERSE A system that redirects engine exhaust forward to help decelerate an aircraft after landing.
29. A system that enables an aircraft to perform an automatic landing.
30. A notice containing information essential to personnel concerned with flight operations but not known sufficiently in advance to be promulgated by other means.
31. The vertical guidance component of an Instrument Landing System (ILS) that defines the correct descent path.
33. An electronic system used to detect and locate objects by sending out radio waves and detecting the reflections.
37. A light or electronic signal used for navigation or warning.
38. The prescribed path that an aircraft follows in the vicinity of an aerodrome, usually before landing.
39. To join or cross a defined course or radial.
40. Wind blowing in the same direction as the aircraft's movement, increasing ground speed.

Down

2. A primary flight control surface on the tail of an aircraft used to control pitch.
4. EFFECT The aerodynamic phenomenon that reduces induced drag when an aircraft flies very close to the ground.
7. AIRSPEED The airspeed reading directly from the aircraft's pitot-static system, uncorrected for errors.
8. FLIGHT RULES Regulations governing flight conducted under conditions where visual reference to the ground is not continuously available.
10. An instrument that measures altitude, typically by sensing atmospheric pressure.
11. A primary flight control surface on the tail used to control yaw.
12. A spinning column of air, such as wingtip vortices created by aircraft.
13. The altimeter setting that causes the altimeter to read aerodrome elevation when on the ground.
16. Hinged surfaces on the trailing edge of the wing, extended to increase lift and drag during takeoff and landing.
19. An electronic device aboard an aircraft that enhances its radar signature and can broadcast identifying information.
22. ROUTE Pertaining to the segment of a flight between departure and arrival terminal areas.
23. Providing navigation guidance to aircraft in the form of specific headings from air traffic control.
25. The power system on an aircraft that uses fluid pressure to operate landing gear, flaps, and other controls.
27. PATTERN A predefined racetrack-shaped course that an aircraft flies while awaiting further clearance.
28. The process of adjusting an instrument to ensure its accuracy.
32. A four-digit code entered into an aircraft's transponder, assigned by ATC for identification.
34. The electronic systems used on aircraft, including communication, navigation, and display systems.
35. FIX A specific point in space identified by navigation aids where an aircraft commences an instrument approach.
36. To exceed the end of a runway, typically during a landing or aborted takeoff.
