Below is one of the part captured from an airline’s “Loadsheet & Load Message”. To start with, let’s learn some basic load control terms.
DOW [Dry Operating Weight] = BW [Basic Weight (Aircraft)] + Crew (and their bags) + Pantry
OW [Operating Weight] = DOW + TOF (Take-off fuel weight)
Block fuel (weight)= TOF + Taxi
Payload ($$$) = PAX + Bag in hold + Cargo + Mail
ZFW = DOW + Payload
TOW = ZFW +TOF
LDW = ZFW + TOF – TIF (Trip fuel)
Next, we should know that there are 3 limiting factors:
- MZFW
- MTOW
- MLDW
Remember: to find the allowed traffic load – must to convert into MTOW and minus OW
Case a (MZFW as limiting factor): MZFW + Block – Taxi – OW
Case b (MTOW as limiting factor): MTOW-OW
Case c (MLDW as limiting factor): MLDW+Trip-OW
Below is another diagram FYI
