Q

Company MFAs
(Climbout, Radar, Visual, outside MSA, OEI, Off-route)

A

Climbout: as SID (EFB climb perf to MSA if none)

Positive Radar: iaw MRC

Visual: must see all terrain

Outside MSA: OPF indicated MORA

OEI: Net gradient (EOSID will achieve)
(Gross Stabilising / Level Off generally clears all terrain in AOC area)

Off-route: MGA

Temp corrections see two charts 8.1.1.3 (High / Low altitude)

Q

Should ATC give temperature corrections to MRC? Should they give safe off-route altitudes?

A

Yes. Minimum vectoring should give safe clearance until resuming own navigation

A

Cat III / II/ OTS / LTS: Cat I RVR

Cat I: NPA RVR/Vis (cloud above MDH)

APV: NPA minima

NPA: NPA RVR/ Vis

Q

Difference between Cat A/B/C aerodrome?

A

A: Routine
B: Specific Briefing
B rest’d: Restrictions (no training)
C: Training or visit

Q

Conversion of Met Visibility

A

HIARL: Day x1.5 / Night x 2
Other Lighting : Day x1 / Night x 1.5
None: Day x 1

Do not use if RVR available, or if result is below 800m

22
Q

What if ground equipment downgrades below 1000’?

A

Continue unless unsafe

23
Q

Visual approach minima

A

2500’ ceiling
(circling minima if higher)

5k vis

24
Q

VFR Enroute Minima

A

1.5km laterally / 1000’ vertically
8km visibility above 10,000’
5km visibility below 10,000’

Class F/G clear of cloud, surface in sight, (below 3000’)

SVFR must be 3km vis, may drop to 1.5 km.

25
Q

Holding at 1500 AAL
When needed, how long?

A

Contingency: 5 mins unless CONT95/99 is higher

Contingency w/o SCF
5 mins unless 5% is higher

Final Reserve: 30 mins

Additional (company): 15 mins where no Altn

Reduced Contingency: 5 mins (unless Cont 90 / minimum kg higher)

26
Q

Discretionary Fuel Penalty

A

3% per hour

Increased ZFW= ΔZFW × 3% × (Block-Taxi

27
Q

Alternate Fuel Planning- Reduced Contingency: minimum figure?

What must we always do with reduced contingency?

A

Highest of Cont90 / 5” @ 1500’ /

A319- 190kg
A320- 204kg
A32N- 170kg
A321- 200kg

  • If no Cont90 figure, greater of 3% trip or 5 mins @ 1500 AAL

Trip ERA must always be nominated with reduced contingency. 20% circle, 25% from destination.

28
Q

How much oil needed?

A

Enough to cover burn for a flight until minimum fuel + 15 mins.

29
Q

Extra Fuel Policy

A

Must be a specific reason

Commander retains final responsibility to adjust if in his opinion it is operationally justified

Company prefers an occasional weather divert to carrying extra routinely

30
Q

Arrival Fuel planning- when in contingency, when in extra

A

If there is a chance a full arrival (e.g. trombone) will be flown as opposed to the routine shorter vectoring, the difference will be carried in the Contingency.

If a delay is anticipated, commander will load this as Extra.
