[QUOTEAlthough you may not recognise all aircraft, many pilots do, [/QUOTE]
I wouldn't bet on it.
Bizjet
Heavy
Regional Jet
Turboprop
4 holer
3 holer
big fecker (antinovs etc)
Light aircraft.
Are all useful
At 5 miles you can't tell much more than that even if you do know the different flavours of boeing or airbus.
And as fro the speeds i just presume its just 160 to 4 like every other aircraft should be doing and 180 on base and 210 on the downwind. Light aircraft 90 knts
