SPO.POL.110 Mass and balance system — commercial operations with aeroplanes and helicopters and non-commercial operations with complex motor-powered aircraft

SI No. 1290/2024

Text in magenta in force from 30 October 2025

1. The operator shall establish a mass and balance system in order to determine for each flight or series of flights the following:

   1. aircraft dry operating mass;

   2. mass of the traffic load;

   3. mass of the fuel or energy load;

   4. aircraft load and load distribution;

   5. take-off mass, landing mass and zero fuel or energy mass;

   6. applicable aircraft CG positions.

2. The flight crew shall be provided with a means of replicating and verifying any mass and balance computation based on electronic calculations.

3. The operator shall establish procedures to enable the pilot-in-command to determine the mass of the fuel or energy load by using the actual density or, if not known, the density calculated in accordance with a method specified in the operations manual.

4. The pilot-in-command shall ensure that the loading of:

   1. the aircraft is performed under the supervision of qualified personnel; and

   2. traffic load is consistent with the data used for the calculation of the aircraft mass and balance.

5. The operator shall specify, in the operations manual, the principles and methods involved in the loading and in the mass and balance system that meet the requirements contained in (a) to (d). This system shall cover all types of intended operations.
