Actually
ferrydude has a point and I'd have to agree with him I'm sorry. The original question (average English/typing not-with-standing) was
why do the airbuses usually have lower speed limit than boeings?
L337 went up the wrong tree straight off the bat (sorry mate
) and everyone else followed his lead presuming it was a question about cruise speeds (sorry guys
). Only
LEM was heading in the right direction
And whoever it was who thought 73's cruise so slow - on a cost index around 30 we're doing .74-.75 between FL330-FL350 in a -300.
Ciao.
