or more to the point, creating the calculation in the first place.
I'm having a spot of bother with a weight and balance calculation. The aircraft manufacturer has not provided arm lengths for crew and fuel tanks.
The original weight and balance sheet states for calculating the aft CofG, "Record scale readings with two "heavy people" in the aircraft (approx 215lb) and add fuel to reach MTOW, then measure wheel weights". Then calculate CofG and check it is in range.
My queries are;
is there a formal way of establishing the arm lengths for crew positions, where in the seat do you measure to?
and how do you establish the arm of a wing tank? Do you just measure to the centre of the tank?
