nikitatattoo,
I have 9000+ hours in the real military, high altitude, jet.
You will not learn easily by jumping into a complex jet, if the jet is simulated correctly.
Go to Microsoft Flight Simulator - FSX - there is a learn to fly section on this.
It is very good for understanding the basics of flight.
Choose the C150 or C172 after some practice.
If more were to do this, there would be fewer performance, stall, etc questions I would think.
Remember flying is about eye / hand coordination with the brain.
You have to first put the information (book reading / theory ) into your brain - THEN go to the aircraft and practice. Otherwise you are just playing a game, guessing, and hoping for the right outcome.
Some have done this in the real jet, and died...
Good luck to you.
