Young man- aviation is beset with these blasted TLAs, and everyone assumes everyone else knows whatever TLA they are spouting means! So I haven't a clue what your TLA means after 41 years in aviation, even though you are obviously very happy with it. Care to enlighten?
And if you have been in aviation for 41 and still do not know what a POH is you really must have had your head in the sand!
