DOC AIRBUS | AMM A320FUSE OF MANUAL (MAGNETIC) FUEL QUANTITY INDICATORS - DESCRIPTION AND OPERATION
** ON A/C NOT FOR ALL
1. General
Manual Magnetic Indicators (MMIs) can be used to find the quantity of fuel in the tanks when the aircraft is on the ground. Electrical power is not required to operate the MMIs.
Before the MMIs are used it is necessary to find the aircraft attitude value.
To find the quantity of fuel in the tanks it is necessary to use conversion tables and this data:
The MMIs each contain a Magnetic Level Indicator (MLI) and its related Magnetic Level Indicator Housing (MLIH). These are fully described in (Ref. AMM D/O 28-43-00-00) and for their use (Ref.12-11-28).

Before the MMIs are used it is necessary to find the aircraft attitude value.
To find the quantity of fuel in the tanks it is necessary to use conversion tables and this data:
- the MMI readings
- the aircraft attitude value
- the specific gravity of the fuel.
