Fuel Flashcards
Block Fuel
Minimum legal requirement at ramp
Taxi/Takeoff/contingency/alternate/final/additional fuel
Taxi fuel
APU Burn
Engine start
Taxi burn
Does not include destination taxi fuel
Trip Fuel
Fuel used between take off and landing
Contingency fuel
Fuel for unexpected changes on route
5% of the trip fuel
5 minutes of the fuel at holding speed at destination aerodrome
3% of the trip fuel if ERA are available
Alternate Fuel
Fuel from the missed approach point to the destination alternate
Highest amount of 2 alternate is used
If no alternate selected 15 minutes of additional fuel in case of engine failure of loss of pressurisation
Excludes the missed approach at the alternate
15 minutes over the destination airfield for additional fuel
Final reserve
Fixed quantity of fuel for worst case:
Jet AC - 30 minutes holding at 1500ft
Piston AC - 45 minutes of cruise flight
Using this fuel = emergency
Fuel above hold at alternate - if no alternate use destination hold
Alternate aerodrome requirements
Minimum 1 alternate for IFR flight unless:
Isolated aerodrome
Or
6 hours+/2 runways/2000ft/5km within 1 hour of ETA
Fuel Tankering
Used if fuel price at destination is high
FPR = price at departure/price at destination
Less than 1 to be considered tankering
Reduced Contingency Fuel (RCF)
Means of reducing contingency fuel to reduce fuel burn or extend range.
Decision point procedure:
RCF1:
Taxi fuel
Trip fuel
Additional Fuel
Must be uplifted if no destination alternate is selected
15 minutes of extra fuel over the destination alternate
RCF Concept
To reduce additional fuel requirement on longer flights to allow more traffic loads.
Either RCF1 - 5% of the fuel from the DP to the destination
Or
RCF2 - contingency fuel for the trip from departure to the alternate (normal fuel planning procedures)
PDP
Pre determined point - used for destinations with no suitable alternates (isolated).
Carry additional fuel rather than alternate fuel:
Jets = 2 hours of fuel including final reserves
Reciprocating = 45 minutes + 15% cruise fuel or two hours cruise (lesser)
This includes final reserves
Decision point procedure purpose
To carry minimum contingency fuel to increase traffic load
What happens to the trip fuel if there is a change in runway and the destination and it is more time consuming arrival
It has to be updated correspondingly
When is only one alternate required
CAVOK = no alternate
Below weather = 2 alternates required (if the alternate weather is good enough take the lower of the 2)
