- 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.
