The mass and balance documentation shall contain the following information: (1) aircraft registration and type; (2) flight identification, number and date, as applicable; (3) name of the pilot-in-command; (4) name of the person who prepared the document; (5) [dry operating mass](https://avioverse.aero/glossary/easa/dry-operating-mass) and the corresponding CG of the aircraft; (6) mass of the fuel/energy at take-off and mass of trip fuel/energy; (7) mass of consumables other than fuel/energy, if applicable; (8) load components; (9) [take-off mass](https://avioverse.aero/glossary/easa/take-off-mass), landing mass, and zero fuel/energy mass; (10) applicable aircraft CG positions; and (11) the limiting mass and CG values. (b) Where mass and balance data and documentation is generated by a computerised mass and balance system, the operator shall verify the integrity of the output data. IR · SPO.POL.115 — Regulation (EU) No 965/2012 · Regulation (EU) 2021/1296 · Air OPS Easy Access Rules · EAR revision 27 Mar 2026 AMC Acceptable means of compliance ## AMC1 SPO.POL.115 Mass and balance data and documentation – commercial operations with aeroplanes and helicopters and non-commercial operations with complex motor-powered aircraft GENERAL (a) The mass and balance documentation should: (1) enable the pilot-in-command to determine that the load and its distribution are within the mass and balance limits of the [aircraft](https://avioverse.aero/glossary/easa/aircraft); and (2) include advise to the pilot-in-command whenever a non-standard method has been used for determining the mass of the load. (b) The information above may be available in flight planning documents or mass and balance systems. (c) Any last minute change should be brought to the attention of the pilot-in-command and entered in the flight planning documents containing the mass and balance information and mass and balance systems. (d) Where mass and balance documentation is generated by a computerised mass and balance system, the operator should verify the integrity of the output data at intervals not exceeding six months. (e) A copy of the final mass and balance documentation may be sent to aircraft via data link or may be made available to the pilot-in–command by other means for its acceptance. (f) The person supervising the loading of the aircraft should confirm by hand signature or equivalent that the load and its distribution are in accordance with the mass and balance documentation given to the pilot in command. The pilot-in-command should indicate his acceptance by hand signature or equivalent.

The operator should establish a system to check that amendments of its input data are incorporated properly in the system and that the system is operating correctly on a continuous basis.
