FLIGHT PREPARATION - FUEL CALCULATION (END)
05 - TRAINEES’ ACTIONS
One of the most important aspects of flight planning is the calculation of fuel requirements. If
no computer produced fuel plan is available, calculations can be made using the information
contained in FCOM 2.05.10 to 60 (Flight planning).
Other factors to be taken into consideration are :
· Weather conditions at destination and alternate (more fuel required due to
holding / delays ?), and en-route requiring weather avoidance and anti-ice
· Notams affecting navigation equipment for the flight
· Aircraft status and if the MEL indicates increased fuel consumption in particular cases
· Expected passenger/cargo load and distribution
· Whether the optimum flight level will be available (a level 4000 ft below optimum will
increase fuel burn by 5%, and a level 8000 ft below optimum increases fuel burn by more
than 10%)
· Fuel tanking requirements and its effect on fuel burn and optimum flight levels
During preflight preparation a comparison should be made between the paper flight plan and
the FMGS calculated burn off. In order that the predictions are valid, the following items
must be inserted :
· Initial cruise altitude in the INIT A page
· Forecast winds and temperatures along the route in F-PLN B page
· Expected steps in F-PLN A page
· Block fuel in INIT B page
If the predictions show that there will be insufficient fuel at destination, a modification to
cruising flight levels may help, or more fuel may have to be loaded.
Some other items of note are national/airline minimum fuel policy and "island reserve " policy
for remote destinations
06 - COMPLETION STANDARDS
· Makes valid fuel requirements calculation and ensures correct quantity loaded before
engine start.
07 - COMMON ERRORS
· Weak knowledge of national and company regulations for fuel minima and alternate
airports.

NORMAL CONFIGURATION
The VAPP displayed on the MCDU PERF APPR page is calculated using the following
formula :
VAPP = VLS + 5 kts + 1/3 of the headwind component
NOTES :
· VAPP is limited to VLS + 20 kt
· Headwind component is computed from the wind inserted in the PERF APPR page
· VLS is the VLS of the landing configuration (3 or FULL) selected on the PERF APPR page.
However the pilot may overwrite the VAPP according to the following formula:
{ VLS
{ or
VAPP = the greater of { VLS + 5 kt *
{ or
{ VLS + wind correction
NOTES :
· The 5 kt* correction is an airworthiness requirement for autoland with A/THR, or
approaches with A/THR active.
· Wind correction is 1/3 of headwind component of reported tower wind, limited to 15 kt. Use
the reported steady wind not the gust.
· When there is a gusty crosswind greater than 20 kt, add 5 kt to VAPP (VAPP may now be
up to VLS + 20 kt)
When CONF 3 is used for landing the CONF 3 prompt on the PERF APPR page should be
pressed. The VLS on the PERF APPR page will change to VLS CONF3. VAPP should then
be determined in the normal manner and managed speed used for the approach.
