Two overlapping radiation patterns are generated, which differ by different keying in the rhythm of the Morse code 'A' (.-) and 'N' (-.) (ON keying). At the intersection of the two characteristics, the characters A and N complement each other to form a continuous tone, which forms the criterion for a course. The aircraft can be guided on the course by listening to the keys A and N and the continuous tone with a simple radio receiver. In addition to the ON keying, there is also a 90 Hz / 150 Hz modulation which indicates a direction rotated by 90 ° or 270 ° in azimuth. Four-course beacons are no longer set up anew, as VOR beacons can better perform their tasks. |

X-BLD | Cross bleed | "Cross-use" of the bleed air for the engine start, larger twin-engine aircraft are usually started with an auxiliary unit ( APU , ASU ); after the first turbine has started, the second turbine is occasionally started by means of bleed air from the opposite (crossfeed) turbine; When restarting an engine that has failed in the air (inflight start, air start), the airspeed is usually sufficient to turn the stationary engine in the wind current (windmilling start) sufficiently quickly for the take-off process (so that no APU or similar is required); however, if the aircraft is too slow, the stationary engine needs bleed air from the running engine to start it up; In the case of the B737 NG or the B777 , the note "X-BLD" is displayed in the cockpit on the engine instruments (EICAS monitor) above the N2 display for the corresponding engine, to indicate that the aircraft has reached the limits for a normal air start (inflight start envelope) and cross-bleed bleed air is required to start the engine |

ZEL | Zero Length Launch System | Start system without take-off distance (even shorter than STOL ); F104 took off from a standing position with a rocket engine. The rocket engine was set up in a locked area near the airfield. This should make it possible to take off directly from the aircraft bunker, even with bombed airfields. That should preserve the second strike capacity of the Western Air Force against the Eastern Bloc. (Synonyms: ZLL, ZLTO, ZELL) | |||
