737 and A320
1Stepprep For 737 and A320 training, these guys are really good at focusing on certain concepts and explaining in a very direct way that is effective with a touch of humour. A breath of fresh air to come across cool guys like these compared to some I have experienced in sim training. If only we had instructors like these for all our airline sim courses.
A320 CBT Computer Based Training on youtube that you would get on your type rating course.
A320 Flight Instrument Simulator For learning A320 automation. Quite handy during the sim part of your type rating course to practise.
STUDENT PILOTS (and good Pilot Instructor revision too!)
See Lift in action It may be old, but its really good, better than seeing still pictures in a textbook.
How the Propeller works I really got into propellers when upgrading my Instructor rating. Why don’t they show you videos like this in the classroom?!
