Ok, I've skimmed the report - not a nice scenario to be presented with. A "crossing descend" followed by "increase descent", followed by "climb" with a controller request thrown in for good measure but it does seem the increase descent was as a result of not following an initial TCAS instruction.
Yep but yet again the fundamentals get missed.
"London, Turkish 1991 TCAS RA standby". Followed smartly by following the TCAS instructions.
Another Turkish training flight with an observer on the jumpseat and they are getting themselves into a pickle. The skipper must be Turkeys answer to Chuck Yeager to be in the LHS of a 777 and a TRI or TRE with only 4300hrs.
