1

Allowed T/O Mass (ATOM)

Max mass an aircraft can be at T/O

Taking into account all possible restrictions and limits

Lowest of:
- MZFM + T/O Fuel
- RTOM (regulated T/O Mass)
- RLM + Trip Fuel


Use the Lowest as your limiting factor!!

2

Block Fuel / Ramp Fuel

Fuel on board at the ramp after it has been prepared for flight

3

Start Up and Taxi Fuel

Amount of fuel expected to be used for start up and taxi

4

8

Mass Change During Flight

Ramp Mass

Minus Start-up and Taxi Fuel

T/O Mass

- Trip Fuel - T/O Fuel

= Landing Mass = ZFM

9

RTOM

Regulated T/O Mass

= Lowest of the MSTOM and the PLTOM

MRJT Error....

Watch out for the maximum ramp mass (mrm) if you are using the ATOM from the RTOM

- If taxi fuel is over 260kg

Only in MRJT unless they specify a ramp mass for you


MRM - Taxi Fuel = RTOM
