No probs tiger :
Takeoff is to be at MTOM = 12154 kg
Start/Taxi fuel = 250kg
so ramp mass = 12404 kg
-----------------------------------------------------------------------
BEM = 1457 kg
Crew/equipment = 280kg
so dry operating mass = 1737kg (may also be called APS)
traffic load = 1155 kg (pax + baggage)
so zero fuel mass = 2892kg
------------------------------------------------------------------------
Block (ramp fuel) = ramp mass - zero fuel mass
= 12404 - 2892
= 9512 kg
