Just want to ask a basic question, when looking at the FCOM on how to do a manual load sheet it says:
DATA
Dry Operating Weight = 42500 kg and CG = 27 % (H-arm = 18.93 m)
Deviation or adjustment = + 100 kg in zone F
Cargo = 5500 kg with the following distribution :
cargo 1 = 2000 kg ; cargo 3 = 1500 kg ; cargo 4 = 1500 kg ; cargo 5 = 500 kg
Passengers = 145 pax with the following distribution :
cabin OA = 50 ; cabin OB = 55 ; cabin OC = 40
Ramp Fuel = 13200 kg ; Taxi Fuel = 200 kg ; Fuel Density = 0.785 kg/l
DESCRIPTION
Enter Master data in (1).
Compute Dry Operating Weight Index using the formula indicated in (2) and report in (3).
Dry Operating Index = 53.4.
My question is about the H-arm. I looked at the Getting to Grips document and there is no definition of H-arm. I understand the H-arm is a reference point but would it stay the same on every aircraft on an identical fleet? And if not, where would you find the specific aircraft's H-arm to enter the Airbus manual loadsheet in the top left box, page 121 in the Getting to Grips document? In this example above, is H-arm = 18.93 a generic figure or is that the one to use on the manual loadsheet?
Thanks for the replies,
