The purpose of altitude alert system to generate a visual and aural warning to pilot when Aeroplane altitude differs from a selected altitude, aeroplane altitude equal to decision altitude, proximity to ground becomes dangerous, altimeter setting differs from standard setting above transition altitude. Question Alerting Systems, Proximity Systems 61 Answer 11
Your aircraft and an intruding aircraft both are tcas 2 traffic alert and collision avoidance system equipped your tcas determines bearing of intruding aircraft Using a specific directional antenna, using bearing function of on board weather radar, comparing gps positions of two aircraft, measuring time lapse between transmission of an interrogation signal the reception of a reply signal. The antennas used tcas ii include a directional antenna that mounted on top of aircraft either an omni directional or a directional antenna mounted on bottom of aircraft. the directional antennas permit partitioning of replies to reduce synchronous garbling. the directional antennas allow tcas to determine bearing of intruder. Question Alerting Systems, Proximity Systems 61 Answer 12
The tcas ii has inputs from radio altimeter in order to Gradually inhibit resolution advisories (ras) when getting closer to ground, stop tcas operation below 25 agl, determine relative height of intruder, to alert crew from a dangerous proximity of ground. connection with radar (radio) altimeter on one hand to inhibit ras when aircraft in close proximity to ground, on other hand to determine whether aircraft tracked tcas are on ground. Question Alerting Systems, Proximity Systems 61 Answer 13
The upper antenna of tcas ii Directional to improve surveillance of intruders, directional because it merged with transponder antenna, omnidirectional to improve surveillance of intruders, omnidirectional because it merged with transponder antenna. the antennas used tcas ii include a directional antenna that mounted on top of aircraft either an unidirectional or a directional antenna mounted on bottom of aircraft. most installations use optional directional antenna on bottom of aircraft. these antennas transmit interrogations on 1030 mhz at varying power levels in each of four 90° azimuth segments. the bottom mounted antenna transmits fewer interrogations at a lower power than top mounted antenna. these antennas also receive transponder replies, at 1090 mhz, send these replies to tcas processor. the directional antennas permit partitioning of replies to reduce synchronous garbling. in addition to two tcas antennas, two antennas are also required the mode s transponder. one antenna mounted on top of aircraft while other mounted on bottom. these antennas enable mode s transponder to receive interrogations at 1030 mhz reply to received interrogations at 1090 mhz. the use of top or bottom mounted antenna automatically selected to optimize signal strength reduce multipath interference. tcas operation automatically suppressed whenever mode s transponder transmitting to ensure that tcas does not track its own aircraft. Question Alerting Systems, Proximity Systems 61 Answer 14
Your aircraft and an intruding aircraft both are tcas ii equipped if transponder of intruder switched off or unserviceable The intruding aircraft invisible to your tcas equipment, intruding aircraft remains visible to your tcas equipment, but only tas (traffic advisories) can be generated, intruding aircraft remains visible to your tcas equipment, but only ras (resolution advisories) can be generated, information available to your tcas equipment two dimensional only. Question Alerting Systems, Proximity Systems 61 Answer 15
