Q

What is a “Re-clearance” procedure in regards to fuel procedures?

A

Flight can be dispatched with another airport as destination and then be re-cleared in flight to possibly continue to original destination if fuel onboard is sufficient. Otherwise we divert to the “new” destination

Q

Define “Destination Hold Fuel”

A

Extra fuel to cater for expected ATC or weather delays at the destination

30 min is added if certain conditions exists +-1h of the ETA:
- Weather forecasted to be close to minima
- Forecast X-wind is above limitations
- TS with FEW CB are forecasted, including TEMPO

Q

If the Commander wants more extra fuel, is that added to Dest Hold fuel?

Study These Flashcards
A

No, it will be added as Extra Fuel

21
Q

Is Dest Hold legally required fuel?

Study These Flashcards
A

No, the Commander can choose to take it off the FPL

22
Q

Define “Additional Fuel”

Study These Flashcards
A

Fuel required if fuel load is not sufficient to:
- allow the aircraft to descend as necessary and proceed to an alternate in the event of engine failure or loss of pressurization and
- having 15 min holding fuel and make an approach and landing

23
Q

Define “Alternate Fuel”

Study These Flashcards
A

Fuel from Missed Approach, flight to alternate, descent and landing + 5% Contingency

24
Q

What “Fuel Schedule” is Alternate Fuel calculated from

Study These Flashcards
A

Long Range Cruise (LRC)

25
Define "Reserve Fuel"
Fuel to fly for 30 min at holding speed at 1500 ft
26
Above what value of fuel discrepancy to we have to start looking into it?
Above 400 kg discrepancy
27
Define CMR in regard to fuel?
CMR (Company Mandatory Fuel) - Fuel required to chosen alternate - 5% contingency fuel applicable to the above - Final Reserve
28
If, in-flight, it becomes clear that you will arrive at destination with less than the required CMR. What procedure can be implemented?
We can continue provided: - Fuel remaining is not less than Final Reserve - There are two separate runways - No delays - Weather is better than the alternate planning minima for the non-precision approach aid with the higher minima serving the two runways being considered - Cross wind is within limits
29
If, during descent, it becomes clear that you will arrive at destination with less than the required CMR. What procedure can be implemented?
Flight may continue if fuel remaining on landing is equal to Final Reserve
30
What number should tankering be limited to?
MLW -500kg
31
When should tankering not be considered?
Destination runway have: - Standing Water - Slush - Snow - Ice
32
What formulas can be used to calculate Maximum allowable Fuel at Departure?
1 Based on Max Landing Weight MLW - 500 kg - ZFW + Taxi Fuel + Trip Fuel 2 Based on Max Take Off Weight MTOW - ZFW + Taxi Fuel
33
What is formula can be used to estimate Fuel Tankering?
1st Sector Taxi Fuel + 1st Sector Trip Fuel + 1st Sector Taxi In/APU usage + 2nd Sector Block Fuel
34
What is the minimum oil quantity for the IAE engines?
11 qt + 0,3 qt/h
35
What is the minimum oil quantity for the PW engines?
14 qt
36
What is the minimum oil quantity for the LEAP engines?
10,6 qt or 8,9 + estimated consumption (0,45 qt/h)
37
When do we start investigating fuel uplift discrepancies?
When difference is 400 kg or above
38
What is the max allowed imbalance between the inner fuel tanks and the outer fuel tanks on the A320?
Inner tanks limit = 500 kg Outer tanks limit = 370 kg
39
What is the max allowed imbalance between the fuel tanks on the A321?
400 kg
40
What the difference achieved by inserting CI = 0 compared to CI = 999?
CI = 0 gives maximum range CI= 1 gives minimum time
41
What can be done to increase fuel temperature? What are the temperature increase effects of these actions?
1. Descend or divert to a warmer airmass. 4000 ft descent gives as 7 deg C increase in TAT 2. Increase Mach nr. An increase of M 0,01 gives approximately 0,7 deg C increase in TAT
42
Is a FLEX or TOGA takeoff preferred when it comes to minimize fuel consumption?
TOGA is preferred as the take off phase becomes shorter
43
Does turing off one pack after start burn more or less fuel?
It burns more
44
How often do we have to perform fuel checks?
At least every 30 min
45
What actions can be done to make fuel last longer when getting close to min fuel?
- Fly MRC speed by setting CI to 0 - Obtain more direct routings - Fly a more optimum flight level - Select as closer suitable alternate
46
What does the term "MINIMUM FUEL" mean?
Informs ATC that all planned airport options have been reduced to a specific airport and any change to the existing clearance may result in landing with less than the planned final reserve fuel
47
When should a pilot declare "MAYDAY MAYDAY MAYDAY FUEL"?
When the calculated usable fuel to be available upon landing at the nearest airport where a safe landing can be made is less than the planned final reserve
48
What is the minimum fuel for take-off?
1500 kg
49
How can we try to get away with a lower value of Contingency Fuel?
By using an ERA. Instead of 5% of trip fuel we can use 5% of fuel required from overhead or abeam the ERA. Then take the higher of the new 5% or 5 min hold @ destination
