sla Nice one. Keep learning the aircraft types and their performance figures, although take some of the manufacturer's figures with a pinch of salt. They will try to tell you that something like the good old SH36 has a ceiling around FL250 or something equally ridiculous. Fair play with a test flight crew and no pax but you will never see one "in the flesh" above FL100 (why not?).

An "airplane" is an aerial device that flies around America. In the UK we have "aircraft" and "aeroplanes". Lose 1 mark in your next progress test.
Hey I even managed to bring America into the thread!
