pinteam I trust your word the ALT has significance. I think I found one particular trap where the missing ALT would be the warning sign - will keep that to myself for the moment.
Can you check your memory banks, however? What you describe here is sure possible,
but if you had moved the ALT SELECTOR before pulling V/S, the
ALT(blue) would be there as usual. Even if the pilot used the V/S to send the A/C the other way.
Please? It doesn't add up.
