An AirBP card is available in the aircraft (in the holder, first page of the POH)

Pilots should prefer to use it for simplicity in administration.

While a booklet of places, where AirBP is available, will also be in the aircraft, a current list can be found here.

If, by circumstance, you are obliged to refuel on another location, in order to be refunded please request an Invoice addressed to Helium Group NV (details are available in the aircraft).
