I would suggest that before you even get into the Cessna, or the Trike Ultrlight for that matter, familiarize yourself with the aircraft, "What are all the parts called?", i.e. Wings (

, if you don't already know the wings... sell the game!

), Horizontal and Vertical Stabilizer, Fuse, Fixed/Retract Gear, Fixed/Variable Pitch Prop, etc.
Next, the physics of flight, i.e., "What
REALLY makes an airplane fly?"
Then read and learn as much as you can about Weather. Different clouds, temperature, thermals, etcs.
After that, learn about the equipment on your aircraft, i.e. the radios, gauges (How does the Altimeter work? What exactly is a Gyro?, etc.), controls, etc.
After that, go into how air traffic works, is routed, different names for specific patterns, etc.
Next, learn about ATC (Air Traffic Control). Read about the terms used, by both the ATC and the Pilot.
Once you go through these readings (actually called Ground School in real life), then get into the plane and start out with the Learning Center's Flight School. Start with lesson one and work your way up into navigation, multi's, helicopters and jets.
And as always, if you get confused, need something explained, or just have general questions, there are always people here to help you!
Good Luck and Happy Landings....
