And a PS, I have been told, and I think the CAAP confirms, that CASA requires weight and balance checks to be on paper and refer to the POH or CASA chart data unless the aircraft manufacturer has approved the electronic device for the calculation.
If you, or someone, could find a reference in black and white to back up that assertion it would be useful.
For commercial ops, use the system of loading in your ops manual whatever that may be. Pretty simple really.
For private ops you are only required to have done a loading check. You are not required to have that with you in the aircraft. Refer to
CAR 139 - documents required to be carried.
Also refer to
CAR 235 - takeoff and landing of aircraft. (5) and (6) specifically;
(5) The pilot in command of an aircraft must not allow the aircraft to take off if its gross weight exceeds, by more than the weight of fuel that would normally be used in flying to its next landing place or planned alternative aerodrome, its maximum landing weight or, if a lesser weight determined in accordance with a direction under subregulation (2) is applicable to the landing at that place or aerodrome, that lesser weight.
Penalty: 50 penalty units.
(6) The pilot in command of an aircraft, must not land the aircraft if its gross weight exceeds its maximum landing weight or, if a lesser weight determined in accordance with a direction under subregulation (2) is applicable to the landing, that lesser weight.
Penalty: 50 penalty units.
Nowhere there does it say anything about how to make the determination. That is left to your discretion.
That is the law, the rest is opinion.
