Mackey SQ2 Weight & Balance for
The Datum line is the leading edge of the wing.
The aircraft is to be leveled in the flight attitude
(level between bottom of front and rear spars) and each wheel weighed using aircraft scales.
Install 2 gallons of fuel into each tank then drain tanks by disconnecting the fuel line at the engine.
This will add the unusable fuel to the aircraft weight.
(ensure that oil levels are at maximum recommended)
If leading edge slats are removed, the rear C of G limit becomes 21".
