I stumbled
on this by accident this evening, and I'm suitably impressed (it doesn't take much).
It's a
little online course for passengers of a light aircraft, so that if they need to take control of the aircraft (dread to think) then they have some idea of what to do. It's done with 'Flash', complete with sound so it's interactive, and has a little twenty or so question quiz at the end and allows your passenger to print off a certificate at the end. Another useful print out it can provide is an Emergency Checklist for the passenger.
There's also a load of
other online courses there too which look useful (but I've only started to fiddle with the 'Engine & Propellor' one so far)
