1 Fuel Policy Flashcards
Pre flight planning. What is the basic Tenant of BA fuel policy?
To land at 2 airfields or 2 RWYs at the same airfield with at least reserves in tanks. The commander must take into account any information upto the point of dispatch. OMA 8.18.1-20
What is the weight change line on OFP used for?
For an increase in ZFW upto 5T
More than 5T increase requires a new cirrus.
OMA 8.18.2
Define Reserve Fuel
Reserve fuel is the minimum fuel required to be remaining in tanks at normal landing.
Calculates as 30 minutes holding fuel at 1500 ft clean at Planned Landing Weight at the Alternate Airfield or destination if no alternate is required.
Define contingency fuel?
1) SCF 99%, 95% or 5 mins holding fuel @ 1500’ at PLW
2) No ERA - 5% x trip fuel or 20 mins flying time at planned trip consumption.
3) ERA avail - 3% x trip fuel or 20 mins flying time at planned trip consumption.
In all cases a minimum of 5 mins holding fuel @ 1500 ft clean at PLW
OMA 8.18.10
How can you dispatch with a last minute increase in fuel without refuelling?
1) CI 0
2) Reduce below statistical taxi fuel
3) reduce contingency fuel to a minimum of 5 minutes
4) Dispatch without a destination alternate
OMA 8.18.16
How can you dispatch without a destination alternate?
a) planned flight time less than 6 hrs
b) 2 independent runways
c) Visibility ETA +/- 1 hr = 5 km
d) Cloud ceiling ETA +/- 1 hr = 2000’ or circling + 500’
e) Increase reserve fuel by 50% (ie diversion fuel is replaced by 15 mins holding at 1500 ft)
OMA 8.18.8
What flight time and temperature at destination would need you to look at the tankering winter restrictions?
1 hr 15 mins - 4 hrs
OAT at destination is -2 C to + 10 C with preciptation or high himidity (Dew Point within 2 C of OAT)
further details in OMA 8.18.19
What are the fuel penalties for changing the Cirrus weights?
1) Use cirrus wt change line or 3% / HR
2) Inc ZFW = T+C+D+R( times) x 4%
3) Inc Div = T+C(times) x 4%
4) inc Fuel = T(time) x 4%
OMA 8.18.20
Define a fuel shortfall in flight?
If a fuel check shows that the aircraft will land at destination with less than Div + Res (less than total reseve)
OMA 8.18.23
If you might land with less than Div+Res what should do?
1) Reduce fuel consumption (CI 0?)
And/OR
2) Select a closer destination alternate
Or land somewhere else ie divert
OM A 8.18.23
How can you continue towards destination when a fuel check indicates less than Div+Res?
Define landing assured.
A landing can be completed in the event of any forecast WX deterioration AND any plausible single failure of any GND AND airborne facilities
(eg a failure which would downgrade the planned ldg status from Cat 3A to Cat 2)
OM A 8.18.23
What does a minimum fuel call to ATC mean?
Having committed to an aerodrome, any change to the existing clearance to that commited aerodrome may result in landing with less than reserve
OMA 8.18.24
What is a fuel emergency?
MAYDAY MAYDAY MAYDAY FUEL and fuel remaining in mins, when landing at the nearest Aerodrome is calculated to be less than Reserves.
OMA 8.18.24
An altitude of 4000 ft below the optimum incurs a penalty of XX % of fuel.
Same question but 8000 ft below optimum
4000 ft below — Approx 5 %
8000 ft below — More than 10%
