'Follow the TCAS commands on your PFD, no more, no less, and keep it smooth. KISS principle is never more relevant than when the s*** hits the fan...'
Well, yes, use whatever you have. But I am not aware of 'TCAS commands' as such yet; Boeing simply tells you where not to be pitchwise, and Airbus does absolutely nothing on the PFD, so that's one case at least it where helps to have a rule of thumb, and I just don't know about Embraer etc. In all cases you still need to know roughly the right rate to react in order to avoid depositing the pax on the ceiling or their knees, while still achieving worthwhile vertical separation. It helps to use the thinking time between the TA and the RA to think about the response needed, that is all. If you get an RA then just count slowly up to 5 as you carry out the manoeuvre, that paces you nicely. A Eurocontrol study program ('Emotion 7'?) showed pilots tended to fall into two distinct camps in responding to RAs, either too much or too little, with precious few in between getting it right.
The Far Eastern 757 would have had the Boeing 'lozenge' appear, but he apparently didn't know what to do with it, or how fast. But we should at least be grateful he went the right way (see many other threads about the dangers of deciding you know better which way to go).
