Goodmick/Beagle,
For your info the QQ trim runaway in the J during AAR was infact inadvertant trimming by the TP. Aparently it has happened before a few times ay QQ, but no occurences reported by operators. The stick top is a bit crowded and it can take time to learn how to "grip" it without pressing a button.
On the thread of useless trials, on 2 occasions, in two different transport aircraft I had to instruct the TP how to fly the thing before he could conduct the trial. One was a USAF KC135 exchange mate who had to conduct an airdrop trial. He had 4 hrs C130 and had never dropped anything before. Another time, when it came to the trial, in a blatantly non-aerobatic aircraft, I was to be co and we had to get an auth from the chief TP who asked "how many spins were we going to do?"
Also I think experienced operator are more than capable of assessing what new/"average" pilots could cope with.
