TRIP/TIME
The taxi fuel defaults to a pre set value. The flight crew may modify this value.
The Trip / Time field is calculated by the FMGC once predictions are available.
RTE/RSV
The reserve fuel for the route. The flight crew may enter a value (in tons) or a % value.
LZFW CG/ZFW
The flight crew enter the Zero Fuel Weight CG and the Zero Fuel Weight into the boxes for the LSK 1R. Enteries are XX or XX.X for CG and /XXX for ZFW. They may be combined as XX/XXX
ALTN TIME
This is the alternate trip time and fuel, if an alternate airport exits in the flight plan.
FINAL TIME
The flight crew may enter a Final fuel or time, from which the FMGC will calculate associated holding fuel/time, assuming a racetrack pattern at 1500 ft above the landing runway, at green dot speed
EXTRA TIME
This is the extra fuel and the available flight time it represents for holding over the alternate or primary destination.

The prompt appears after the ZFW has been entered.
