The Cessna 120-140 Association Forum

The Garmin G5 I installed asks for the airplane to be set to the "level flight attitude" for calibration. I know you also have to do this for weight and balance. What's the best way to determine this? I was thinking jack the tailwheel until the underside of the wing is level. Close enough?

From the TCDS...
Specifications Pertinent to all Models
Datum: Leading edge of wing
Leveling means: Top edge of sheet along fuselage side aft of doors

The strip of aluminum that goes from the door to the tail is the leveling point for and aft. The ridge of the floor where the trim and fuel valve is the left right leveling point. (let some air out of one of the tires to achieve level)

Thanks guys, I guess I need to review the TCDS a little more.
