CX Fuel Policy

Question 1

General

• minimum fuel required

Answer 1

Min fuel required is
-fuel required
-sufficient to divert at any point to ERA
-carry out approach + landing
-30 mins final reserve fuel
AND
-sufficient to divert with OEI/depress (EDTO both)
-5% contingency (only in planning)
-15mins min reserve fuel

Question 2

What is taxi fuel

Answer 2

Fuel to taxi (20 mins - set for each aircraft but maybe altered based on stats)
Includes APU and start up

Question 3

What is trip fuel

Answer 3

Actual trip fuel from take off to landing
T/o, climb, dept SID
Cruise
Descent, arrival, STAR
approach and landing

Question 4

What is contingency fuel

Answer 4

Used to cover;

• alt restrictions
• route changes due wx/atc
• errors in winds/temps
• expected delays

Planned using PBC or 5%

Question 5

What is additional fuel

Answer 5

Extra added to cater for

• enroute depress or eng failure or both to divert to ERA plus 15 mins @1500ft
• for EDTO included additive for severe icing plus APU use

Question 6

What is alternate fuel

Answer 6

• missed approach at dest
• climb to crz
• crz to ALT plus 5%
• descend and approach to land
• at CI 0

Based on default routing but made up to 90nm if close to destination
2hrs for isolated (island reserve)

Question 7

What is final reserve fuel

Answer 7

Is min fuel aircraft shall land with except after depress and/or engine failure

(If some fuel is unusable, enter into FM, increase by unusable amount)

FRF = 30 mins at 1,500ft, ie 2.6t

Question 8

What is minimum reserve fuel

Answer 8

-min fuel at touchdown after a depress and
/or eng failure
-15mins at 1,500ft
- Mayday call is to be declared if landing below final reserve fuel

Question 9

What is min divert fuel

Answer 9

Alternate + Final reserve fuel

If a malfunction results in some unusable fuel then FM should be updated to reflect this

Question 10

What is extra fuel

Answer 10

• Any additional fuel for exceptional circumstances or operational considerations
• alt+Mand+rec extra should equal at least FR therefore aircraft always lands with 1hr fuel

Question 11

What is discretionary fuel

Answer 11

-Any extra the captain chooses to carry

Question 12

How is an in-flight reduction calculated

• enroute

Answer 12

1. Airport requires 2 separate runways or another airport within 60 miles
2. Actual / forecast wx to be Abv NPA alt mins
3. Crosswind blw limits
4. ATC no known delays
5. Fuel remains able to:
   - P.Pos to dest
   - 5% abeam last ERA
   - 30 mins hld at 1,500ft
   - appch to land

Question 13

How is that in-flight reduction calculated once on descent

Answer 13

• If likely to land with less then MDF can continue to land with final reserve fuel

Question 14

When is PERF FACTOR used

What effect does IDLE FACTOR have

Answer 14

PERF FACTOR: Adjusted if actual aircraft fuel flow is different to baseline. Can also be used to adjust for an MEL

IDLE FACTOR: Adjusts FM predictions
+ve earlier TOD
-ve later TOD

Question 15

What normal Isolated airport fuel once in flight

Answer 15

P.pos to dest
Hold overhead for 2hrs
Appch and ldg

Question 16

What parts of the fuel plan can the commander adjust

Answer 16

Taxi,
trip,
Cont - reduced by max 10mins, min of 5 mins left
Alt

Question 17

What is “MINIMUM FUEL”

Answer 17

Will be declared if it is foreseen that any further delay or change of clearance shall result in landing with less then finalise a fuel
NOT AN EMERGENCY

Question 18

What is “MAYDAY FUEL”

Answer 18

Shall be declared if planning to land with less than final reserve fuel
EMERGENCY

Question 19

Cost index 0 vs 150

Answer 19

0 is Minimum trip fuel

Anything above is increased fuel but reduced time

Question 20

What is normal isolated airport fuel

Answer 20

Pres Pos to Dest
Hold 2hrs overhead at cruise alt
Make approach and landing

Question 21

In flight, what is normal fuel

Answer 21

Always need fuel sufficient to

1. Pp to dest
2. Make an approach and landing
3. Divert to alt plus 5%
4. 30 mins FR
