Took off easterly,a bit b4 Eva that day, in not your typical sunny LA weather with winds up to say 7000' being no factor for the climb(in a 74-4 just below max TOM).
Of course a direct track overhead Mount Wilson after t/o was no option, even with a slats extended climb and 250kts.
Having flown a mix off meds and heavies it strikes me how often ATC seems to have no clue of the ac performance, especially in areas like SA(Quito-Bogota, although Quito is getting much better).
Was just wondering how much training our ATC colleague's get in ac performance.
Any ATC lads/ladies who can enlighten?
