1. Read the manual and setup your key-bindings to manage the "h" shaped throttle
2. Follow the inbuilt tutorial (Plugins- TBM 900)
3. Watch some first class Youtube videos on things like start-up, taxing, take-off and landing technique
4. Follow the checklists (the most are accessible via the G1000 MFD), otherwise use the real TBM 900 manual. Link within the aircraft manual
5. Learn, fly, enjoy.
This aircraft is a bit more complex and things may brake, if you do not care about correct handling. You can prevent 90% of the errors by reading, informing yourself in advance and by following most of the procedures. If you succeed on the first flights, the TBM is one of the most fun and educational products for X-Plane.
