FLIGHT PLANNING – FUEL TANKERING
Fuel price variations at different airports may require carrying more
fuel than the minimum required on a flight leg. The procedure of
loading this extra amount of fuel (or surplus fuel) in order to minimize
fuel costs is known as Fuel Tankering.
Since the surplus fuel tankered results in additional fuel burnoff (due to
the weight increase) it is important to analyze the costs of the extra
fuel transportation operation.
The following tables are designed to determine the break-even fuel
price on departure airport and it may be used whenever there is
difference on fuel price comparing to destination. Tables are provided
for LRC and MSC cruise schedule.
Enter the trip distance on the table and read the fuel surplus ratio
according to cruise altitude. The break-even fuel price is the price at
departure multiplied by the fuel surplus ratio. If break-even fuel price is
lower than destination price, it is economically feasible to execute fuel
tankering.
The additional maintenance costs involved with increased weight
operations (additional brakes and tires wearing) are not considered. It
is important to remind that whenever fuel tankering is considered, the
estimated landing weight at destination should be lower than the
Maximum Landing Weight.
Example
Analyze the possibility to proceed with fuel tankering between two
airports distant 600 NM from each other, using LRC speed schedule
cruising on FL350. Consider the following fuel prices:
Departure Airport: 1.80 US$/Gal.
Destination Airport: 2.00 US$/Gal.
•
Enter the LONG RANGE CRUISE table for 600 NM trip
distance and FL350, the FUEL SURPLUS RATIO is 1.06.
•
The BREAK-EVEN PRICE is 1.80 (price at departure)
multiplied by 1.06 = 1.908 US$/Gal.
Since fuel price on destination airport (2.00 US$/Gal) is greater than
break-even fuel price (1.908 US$/Gal), it is economically feasible the
fuel tankering operation between these two airports.
