Command Assessment Questions Flashcards
When do we not need a
Destination Alternate?
OMA 8.1.2.2.2.4
- Flight < 6 hours
- Vis 5 km +
- Ceiling 2,000 feet, or Circling + 500 feet if greater
- Two Separate Runways
When can we consider
Runways to be separated?
OMA 8.1.2.2.2.4
- Separate Approach Procedures based on Separate Approach Aids
- If they cross a blockage on one does not prevent the planned operation on the other.
When do we require two
destination alternates?
OMA 8.1.2.2.2.3
- If desination weather is unavailable.
- If destination is below planning minima for ETA +/- 1 hour.
- Landing not assured at destination as landing depends on:
- Specific Wind Component, or,
- Runway State.
When planning for an alternate,
the TAF indicates in a PROB/TEMPO
that the weather will be below limits.
Can this alternate be used?
YES
PROB/TEMPO can be disregarded
What is the planning minima
for a
Take-off Alternate?
- At or above the minima for the expected instrument approach.
- Any limitation related to:
- One Engine Inop, or
- Dispatch under MEL
Shall be taken into consideration
Within what distance must a
Take-off alternate be?
- 1 hour still air flight time at 1 eng inop crz speed.
- 320 nm
Within what distance must a cruise alternate be?
- A319 - 380 nm
- A320 - 400 nm
What is the planning minima
for a destination alternate
if only a NPA
is available?
- MDA + 200 feet
- RVR + 1,000 m
How long is a TEMPO forecast
expected to last?
- Individually less than one hour each episode.
- In aggreagate less than half of the period specified.
How much extra fuel should be
carried for LVPs?
- Half an hour
- About 1,000 kg
What is Final Reserve Fuel?
- 30 minutes holding fuel
- 1,500 feet above Destination Alternate
- ISA Conditions
- Expected Weight overhead the Destination Alternate Aerodrome.
If planning to tanker maximum fuel,
what are the maximum lnding weight
considerations to base your tanker
figure around?
MLW - (1% OF MLW)
- A320 LW = MLW - 660 kg = 65,340 kg
- A319 LW = MLW - 610 kg = 60,390 kg
When should you not tanker fuel?
- When you expect to land on a contaminated or slippery runway.
- When you expect to land on a performance limited runway.
What is contingency fuel?
- 5% of trip fuel, or
- 5 minutes holding
- 1,500 feet
- above destination aerodrome
- ISA conditions.
What is contingency fuel for?
- Unforseen circumstances:
- Unfavourable FL
- Unfavourable Track
- Unfavourable Unforecast Wind
What is the minimum RFF category for
Departure, Destination &
Alternates?
- Departure/Destination:
- 4 (Temp Downgrade < 72 hours)
- Alternates:
- Non-UK: 4
- UK : 5
When can we continue to fly to destination knowing
that we will get there below CNR?
- Landing Assured at Destination
- EAT or Maximum Delay Known
