That link should be sobering reading then.
For those who don’t want to read it, in essence it refers to an EASA study of 1176 RAs in 2020 that found:
- The overall RA compliance (for all RAs) at 8 seconds after the RA 38% (Method A) or 55% (Method B) of RAs were flown with the required vertical rates, and at 12 seconds after the RA 55% and 54%, respectively.
- Opposite responses (i.e. those responses carrying the highest risk) at 8 seconds were recorded in 34% of cases in Method A and 1% in Method B. At 12 seconds 17% and 1%, respectively.
I always far preferred the Boeing “buckets” to the red/green VSI on the 320, but auto TCAS absolutely is a brilliant invention - I agree wholeheartedly on your comments about Airbus manuals.
The question for airlines, regulators and manufacturers should be; How did they create pilots who fly up when they should have flown down?
