Regulation (EU) No 965/2012 AIROPS : Air Operations
Revision 21, September 2023
NCO.POL.100 Operating limitations – all aircraft - Regulation (EU)
2018/394
- During any phase of operation, the loading, the mass and, the centre of gravity (CG)
position of the aircraft shall comply with any limitation specified in the AFM or equivalent
document.
- Placards, listings, instrument markings, or combinations thereof, containing those operating
limitations prescribed by the AFM for visual presentation, shall be displayed in the
aircraft.
NCO.POL.105 Weighing - Regulation (EU) 2018/1975
- The operator shall ensure that the mass and, the CG of the aircraft have been established by
actual weighing prior to the initial entry into service of the aircraft. The accumulated
effects of modifications and repairs on the mass and balance shall be accounted for and
properly documented. Such information shall be made available to the pilot-in-command. The
aircraft shall be reweighed if the effect of modifications on the mass and balance is not
accurately known.
- The weighing shall be accomplished by the manufacturer of the aircraft or by an approved
maintenance organisation.
GM1 NCO.POL.105 Weighing - ED Decision 2018/003/R
GENERAL
- New aircraft that have been weighed at the factory may be placed into operation without
reweighing if the mass records and, balance records have been adjusted for alterations
or modifications to the aircraft. Aircraft transferred from one EU operator to another
EU operator do not have to be weighed prior to use by the receiving operator, unless the
mass and balance cannot be accurately established by calculation.
- The mass and centre of gravity (CG) position should be revised whenever the cumulative
changes to the dry operating mass exceed ± 0.5 % of the maximum landing mass or, for
aeroplanes, the cumulative change in CG position exceeds 0.5 % of the mean aerodynamic
chord. This may be done by weighing the aircraft or by calculation. If the AFM requires
to record changes to mass and CG position below these thresholds, or to record changes
in any case, and make them known to the pilot-in-command, mass and CG position should be
revised accordingly and made known to the pilot-in-command.
NCO.POL.110 Performance – general - Regulation (EU) 800/2013
The pilot-in-command shall only operate the aircraft if the performance is adequate to comply
with the applicable rules of the air and any other restrictions applicable to the flight, the
airspace or the aerodromes or operating sites used, taking into account the charting accuracy of
any charts and maps used.
