Wing water ballast load:
When determining the max. permitted wing water ballast load m
WB_Wing
the
following data are helpful:

Maximum all-up mass with water ballast m
max
[kg]
o
Empty mass of the aircraft m
empty
[kg] – see sections 6.2.2 and 6.2.3
o
Payload in cockpit m
Cockpit
[kg]
o
Fin water ballast m
FT
[kg] – see section 6.2.5
The calculation of the maximum payload of the water ballast in the wings m
WB_Wing
in kg is carried out using the following formula:
m
WB_Wing
= m
max
– m
empty
- m
Cockpit
– m
