16
Q

How is contingency calculated (with statistical data avail)?

A

It is the greater of CONT95 / CONT99 or

5 minutes of holding time at 1500ft overhead destination in ISA conditions

17
Q

How is contingency calculated (no statistical data avail)?

A

It is the greater of 5% of the trip fuel or

5 minutes of holding time at 1500ft overhead destination in ISA conditions

18
Q

How is reduced contingency calculated (statistical data avail)?

A
  • It is the greater of CONT90 or
  • 5 minutes of holding time at 1500ft overhead destination in ISA conditions or
  • 190 (A319), 204 (A320ceo), 170(A320neu), 200(A321neo)
19
Q

How is reduced contingency calculated (no statistical data avail)? What is required to reduce contingency?

A
  • It is the greater of 3% trip fuel or
  • 5 minutes of holding time at 1500ft overhead destination in ISA conditions or
  • 190 (A319), 204 (A320ceo), 170(A320neu), 200(A321neo)
  • An enroute alternate is required
20
Q

What is covered by alternate fuel?

A
  • a missed approach at destination
  • CLB CRZ and DES to alternate
  • approach at alternate
21
Q

If two alternates are planned? What is the fuel figure shown on the OFP?

A

It’s the fuel to the alternate which is requires more.

22
Q

How is final reserve fuel defined? What if no alternate is planned?

A

30 minutes holding over destination alternate
in 1500ft
ISA conditions
at the estimated weight

If no alternate is planned, the hold is calculated over destination.

23
Q

What is additional fuel used for? How is it calculated?

A
  • It is used when no alternate is planned.
    In this case it’s 50% of the reserve fuel. (15 minutes hold)
  • It is used for special considerations for engine out or loss of pressure at a critical point
24
Q

When should extra fuel be considered? Name some examples!

A

Only if the strong possibility exists that it will be used.

  • TS forecast
  • WX at minimums at destination
  • freezing FG/RA/DZ
  • snowfall
  • ATC delays
  • icing enroute
25
Q

What is the penalty of extra fuel carried? (in % per hour)

A

3% per hour

26
Q

What time frame is considered for the weather forecast suitability check of destination and alternate?

A

± 1 hour of ETA at that aerodrome

27
Q

What weather information is used for planning of the departure airport suitability?

A

Actual weather

28
Q

May CMV/RVR conversion be used at planning stage?

A

No.

29
Q

When is a takeoff alternate required? Which limitations must be considered?

A

When aircraft performance or weather preclude a return to destination.
- OEI and MEL related limitations must be considered.

30
Q

When are two alternates required?

A
  • If the WX forecast is below minimum for the expected approach at destination
  • if no WX data is available
  • if landing performance is not assured due to specific wind component / runway state
31
Q

For destination and enroute alternate planning, what approach minima can be used?

A

Approach minima one category lower than what is available.
For CAT 2+3 / OTS CAT2 / LTS CAT1 = CAT 1 RVR
For CAT 1 = NPA RVR/VIS and ceiling > MDH
For APV = NPA minima
For NPA = NPA RVR/VIS + 1000 and ceiling > MDH + 200
For circling = circling

32
Q

During planning phase (suitability check) a TAF indicates “FM” or “BECMG AT”. When are weather minima applicable? How is wind considered?

A

Applicable at start of FM / BECMG AT for both improving and deteriorating conditions.
Mean wind must be within minima. Gusts may be disregarded.

33
Q

During planning phase (suitability check) a TAF indicates “BECMG”, “BECMG FM”, “BECMG TL” or “BECMG FM TL”. The conditions are deteriorating. When are weather minima applicable? How is wind considered?

A

Deteriorating conditions are considered at the start of time / time frame.
Mean wind must be within minima. Gusts may be disregarded.

34
Q

During planning phase (suitability check) a TAF indicates “BECMG”, “BECMG FM”, “BECMG TL” or “BECMG FM TL”. The conditions are improving. When are weather minima applicable? How is wind considered?

A

Improving conditions are considered at the end of time / time frame.
Mean wind must be within minima. Gusts may be disregarded.

35
Q

During planning phase (suitability check) a TAF indicates “TEMPO”, “TEMPO FM”, “TEMPO TL” or “TEMPO FM TL”. The conditions are deteriorating with SHRA and TS. When are weather minima applicable? How is wind considered?

A

Weather is not applicable. Wind and gusts may be disregarded, because this is a short lived condition.

36
Q

During planning phase (suitability check) a TAF indicates “TEMPO”, “TEMPO FM”, “TEMPO TL” or “TEMPO FM TL”. The conditions are deteriorating with FOG. When are weather minima applicable? How is wind considered?

A

Weather is applicable, as it is persistent.

Mean wind must be within minima. Gusts may be disregarded.

37
Q

During planning phase (suitability check) a TAF indicates “TEMPO”, “TEMPO FM”, “TEMPO TL” or “TEMPO FM TL”. The conditions are improving. When are weather minima applicable? How is wind considered?

A

It should be disregarded.

38
Q

During planning phase (suitability check) a TAF indicates “PROB TEMPO”. When are weather minima applicable? How is wind considered?

A

Deterioration may be disregarded.

Improvement should be disregarded including mean wind and gusts.
