2021年8月6日 · Tech Log - TCAS RA @ Low Level - If you receive a Descend TCAS RA above the inhibit height of 1000' ft (+/- 100 ft) what aural alert does the system generate as (or if) you descend below the inhibit height? If someone could point me towards some supporting documentation that would be much appreciated. Cheers.

2009年9月16日 · TCAS RA orders must be followed even at max ceiling altitude with CLIMB orders. Stall warning must be respected. In alternate law it is not wise to be at FL390. In normal law stall warning does not apply. Alpha protection and Alpha floor do. Get the best your airplane can give you and pray...

2008年10月4日 · TCAS: I gave some exampes where listening and doing what the RA tells you do, could get you in trouble. I can't speak for airliners, but TCAS installed in the planes I fly, can only tell you to climb or descend...not turn right or left, or slow down, or wait and see, or whether there is a radio tower just below you..on and on.

2009年6月26日 · During the TCAS RA recovery the TCAS is the Air Traffic Controller, and all intructions from ATC must be ignored. A call to ATC of "TCAS RA" is potentially dangerous, as it degradres the monitoring capacity of the PNF, may distract the PF and may invite a clearance from the ground controller which conflicts with the TCAS clearance. Confusion ...

2025年2月26日 · Tech Log - TCAS RA without receiving TA beforehand? - Hi, Like the title says, is it possible a flight could get an RA issued without being issued a TA before? On aircraft such as A320 which has automatic TCAS BLUE, how would such a system cope with the RA if "TCAS BLUE" wasnt armed by triggering the TA?

2025年2月26日 · Airbus has provided memory items for that case that have been changed a little bit with the advent of Auto-TCAS, find them in OM-B - PRO - ABN - SURV - [MEM] TCAS WARNING - RESOLUTION ADVISORY. In a nutshell - if the auto TCAS works as intended and as required, that is fine and acceptable.

2008年10月13日 · Safety studies on TCAS estimate that the system improves safety in the airspace by a factor of between 3 and 5.However, it is well understood that part of the remaining risk is that TCAS may induce midair collisions: "In particular, it is dependent on the accuracy of the threat aircraft’s reported altitude and on the expectation that the threat aircraft will not …

ATC Issues - TCAS TA vs TA/RA on ground - Soooo, I was having my briefs removed after my initial on a new jet and the point about selection of TA only when taxiing and TA/RA when cleared to line up apparently did not please my good fellow as much as one would expect. Habitual from a number of years and when trying to

2021年8月9日 · Do Not Climb RA (after an initial Descend RA). This is done to minimize the displacement from the TCAS aircraft’s original altitude. after ALIM feet of separation has been achieved, the resulting Do Not Descend [...] RA is designated as corrective. [...] In Version 7.1, the RA is annunciated as “Level Off, Level Off.

2025年1月17日 · Accidents and Close Calls - TCAS RA Phoenix - Del Prado is right , because TCAS uses a fixed antenna , it is not a radar , it was designed as last minute anti collision tool , not for a display of traffic hence the poor resolution in azimuth .When it was introduced I remember reading it was 11 decrees, resolution if
