Q

How is Destination Alternate Fuel calculated?

A

Where an alternate is planned, the fuel is:

110% of Trip Fuel from destination to alternate, plus

60 nm to cover:
At Destination -
-missed approach,
-departure

and 
At Alternate -
 -arrival, and 
 -approach fuel

  2. make an approach and landing and
  3. land with 15 minutes holding fuel at 1500 ft above the aerodrome in ISA conditions. (S6.1.9)

25
Q

What is the definition of an Isolated Destination Aerodrome?

A

A destination aerodrome from which the

trip fuel to the nearest aerodrome that could serve as an alternate is

more than 2 hours at the planned cruising level above the destination aerodrome. (6.1.15)

26
Q

What will the flight plan have for all flights to an IDA?

A

A PNR to an en-route alternat

e. (6.1.15)

27
Q

What is the destination alternate fuel requirement for an IDA?

A

2 hours at the normal cruise rate above the destination aerodrome plus FR. (6.1.15)

28
Q

How does the FPM treat the IOT destinations?

A

VARA will always plan a suitable alternate that is not an IOT aerodrome.

More conservative than IDA requirements
(6.1.16)

29
Q

What are the special fuel requirements?

A
  • ONS, KTA, PHE, BME and BWX
  • between April 1 and October 31,
  • 10pm to 8 am,
  • alternate required, or holding until after 0800.

Any flight to Ravensthorpe must have an alternate (not ESP), anytime of the year.

International flights ‘MAY’ be required to carry a company alternate. When there is no regulatory alternate requirement then must carry 60 minutes holding. Ferry flights are exempted.
(6.1.17)

30
Q

What does it say about changes to ZFW?

A

If actual ZFW (load app) > EZFW (OFP) then the Minimum Required Fuel must be recalculated.

Up to and including 1000 kg, add the delta burn + 50 kg.

If more than 1000 kg, contact dispatch. They will tell you new figures which must be added to the corrected column. (6.2.1)

31
Q

How do you calculate fuel required for in flight re-planning?

A
  • Trip fuel to the destination,
  • destination alternate fuel or ALT NIL fuel (not required once proceeding to an alternate,
  • 10% cont. on above plus
  • weather and traffic holding if required, and

-FR.

32
Q

If you are going to an unplanned alternate when runway lighting is required, what is the additional fuel requirement?

A

Use ‘call out time’ table from Docunet.

Subtract the ETI to the destination.

The answer is the holding time. (S6.2.2)

33
Q

Does the Call Out Times table include the 30min prior to ETA interval required by CASR pt121 MOS?

A

Yes it does

S6.2.2

34
Q

If there is holding requirements due weather/RAIM etc at your unplanned alternate, how does that affect the holding time required for the lighting call out time?

A

They are concurrent,
ie inter fuel may be the same fuel as holding fuel for lighting.

(S6.2.2)

35
Q

How is DESTination Alternate fuel or ALT NIL fuel to be managed?

A

It cannot be burnt until landing is assured.

S6.2.2

36
Q

When can FR be burnt?

A

Only in an emergency can FR be used before the end of the landing roll.
(S6.2.2)

37
Q

What are the allowances for a)STAR,

b) straight in approach and landing,
c) extended approach, and d)MAPP?

A

a) STAR -300kg
b) Straight In App& ldg -120kg
c) Extended App -120+ 180kg
d) MAPPto 1500ft -100ft

38
Q

What is the fuel burn per hour for APU use on the ground and in the air?

A

130 kg/hr.

S6.2.2

39
Q

Paraphrase the Commitment to Destination paragraph?

A

Once within 60 mins to the destination,
a weather alternate is NOT required unless:
-ETA -30 / +60, the forecast is less than the alternate minima as per the CAT C MIN table.,

provided:
-the destination is TAF 3, and
-within 3 hours of its start, and
there are no known ATC delays. (S6.2.2)

40
Q

Please paraphrase the new CI fuel policy chart?

A

More than 5 mins early, reduce CI to get on time but not below LRC

Less than or equal to 5 mins early, use OFP CI.

If late, and are duty limit critical, increase CI to fix duty issue (not above CI40).

Less than 15 mins late, OTP of next flight will be affected, and increasing CI will help, increase CI to not above 40. OTP not affected, use OFP CI.

Late by 15 mins or more, if increasing CI bring you within 15 minutes, increase CI to bring ETA within 15 minutes late, not above CI 40. If not, then OFP CI. (6.2.3)

41
Q

Can we flight plan VFR?

A

No

6.3.1

42
Q

If we have the choice to fly in CTA or OCTA, what should we do?

A

Plan in CTA where possible and minimise exposure to non-controlled airspace. (6.3.1)

43
Q

Whose responsibility is it that the flight plan is correctly filed with ATC?

A

The dispatcher.

S6.3.1

44
Q

How should NOTAM’s which may affect aircraft performance be dealt with?

A

Should be a note from the dispatcher addressing them. If not, and the crew are unsure if the effect has been taken into account, contact the dispatcher. (6.3.2)

45
Q

When should the OFP be available to us?

A

No later than:
ETD – 60 Domestic.
ETD-120 International.
(6.3.2)

46
Q

If your forecast was provided more than 1 hour before departure, what justifies not getting another?

A

If the PIC is satisfied the weather will be ok for a return to the departure point within one hour.
(S6.3.4)

47
Q

What is a neat summation of the Aerodrome Estimated Time of Use Chart?

A

ETA +/- 30 for all except Isolated Destination which is -30/+60.
(S6.3.5)

48
Q

If an OFP is changed, what are the responsibilities of the dispatcher?

A

To contact the crew. If they cannot be contacted, the dispatcher will cancel the flight plan to prevent the aircraft departing. (Note from me: this won’t work at an outport) (6.3.9)

49
Q

Can you depart without the correct flight plan?

A

NO. It says so in a note on page 6-15.

S6.3.9

50
Q

What happens with delays?

A

ASA require notification of delays of more than 30 mins. Dispatcher will sort if he is aware. Captain should keep him informed.
(6.3.10)

51
Q

If an offload is required who does the captain contact?

A

Central Ops.

S6.3.11

52
Q

Tech stops. Describe, including captains responsibility?

A

Dispatch will sort. If Captain chooses to apply or remove one, first contact is Central Ops, then dispatch. (6.3.12)

53
Q

Cyclones and volcanic ash?

A

Assessed by FOOG or VA Volcanic Ash Management Team (VAMT). ‘Operational Plan’ sent to Central Ops, Dispatch and crew.
(S6.3.13)

54
Q

If we have any weather concerns, what do we do?

A

Contact VA Dispatch , then VARA OCC, then

the Duty Pilot Manager. (6.3.14)

55
Q

Your destination has no TAF. Is there a requirement?

A

Yes.
Must have an alternate, regardless if it has an IAP or not.
(6.3.15)

56
Q

What are the reasons for an alternate requirement due weather?

A
  • Cloud more than SCT below the minima or
  • vis less than the minima for the likely instrument approach as listed on the CAT C Minima table,
  • thunderstorms or their severe turbulence, And
  • HW/TW/CW greater than the aircraft limits.

(S6.3.15)

57
Q

List some other important reasons for having an alternate?

A

No fuel there,
it’s an IOT port.
(S6.3.15)

58
Q

When are two alternates required?

A

The forecast WX is below the landing minima during the ETU, or

the forecast is not available or does not fully cover the ETU.

59
Q

If two alternates are required, when does this requirement reduce to 1 alternate?

A

When the forecast for the alternate are better than the CAT C Minima DEST column.
