Tee Emm's probably forgotten more about aviation that C will ever know
An observation ...
I have no knowledge of C's experience.
However, Tee Emm is in that group of PPRuNers counted on the fingers of one (probably) or two (just possibly) hands in terms of years/flying hours/breadth of military/airline/GA experience. No Lightnings but some dabbling in Mustangs years ago ..
If my flying and flight management were a fraction as good, I would be more than pleased with myself....
Now, Tee Emm would be the first to admit that he doesn't have the monopoly on wisdom .. however, one would be foolish not to consider his counsel ... even if, at the end of the day, you might choose to disregard it.
