Q

Is dispatch without a destination alternate allowed?

A

Yes, but only if below criteria are met:

Q

What are the planning minima for a nominated take-off alternate & when is one required?

A

Required when the weather conditions preclude a return to departure aerodrome taking into account single engine or any MEL restriction, whichever is more limiting.
Weather reports or forecasts for the take-off alternate should be above the applicable minima for the expected instrument approach.

Q

Regarding take-off alternates, what are the implications of taking off above max landing weight?

A

Auto-land is not certified above max landing weight so a Cat I take-off alternate is required if LVPs are in force at departure aerodrome

Q

Difference between fuel & commercial alternate?

A

Fuel alternate requires less fuel but has minimal facilities available in case of divert
Commercial alternate has fuel and is equipped to deal with passenger needs e.g shops, catering etc

21
Q

What is the minimum rescue & firefighting service category for A319, A320 & A321?

A

A319/A320 - 6
A321 - 7

Departure/destination aerodromes can be reduced to 5 at aerodromes with little movement and further to 4 if reduction not exceeding 72 hours & is notified by NOTAM.

Alternate aerodromes - UK 5, Non UK 4

OMA 8.1.2.1

22
Q

Explain the application of aerodrome forecasts table? OMA 8.1.2.4

A
23
Q

What is easyJet fuel policy?

A

To carry the minimum amount of fuel necessary to safely and efficiently complete the flight while meeting regulatory requirements and maintaining operational flexibility.

OMA 8.1.7.3

24
Q

In flight, if EFOB at destination is less than CNR what should you do?

A

If landing is not assured and/or EAT unknown divert to suitable alternate

If landing is assured & EAT known you can continue and land above final reserve

If landing assured by delay unknown you can continue towards destination but must be able to divert to an alternate at any time until EAT is known

25
Q

Definition of landing assured?

A

Captain deems that landing can be achieved with forecast deterioration in weather & plausible single failures in ground equipment or airborne facilities

OMA 8.3.8.1.3

26
Q

What is taxi fuel and can it be modified?

A

Taxi fuel is fuel for engine start, taxi and APU burn.

Can be adjusted to take account of known conditions

27
Q

What are the approximate taxi fuel burn values?

A

1 engine 7kg/min
2 engine 10kg/min

OMB 5.1

28
Q

How much is the APU burn per hour?

A

120kg/hr (2kg/min)
50kg/hr airborne

OMB 5.1

29
Q

What is trip fuel and can it be modified?

A

Fuel used from takeoff until the commencement of missed approach or landing

It can be adjusted OMB 5.4.2

30
Q

What is contingency fuel & can it be modified?

A

Fuel to cover for possible deviations between planned and actual operating conditions (deviations in CRZ alt, track, wind etc)

If SCF is available contin is greater of
- CONT 95
- 5 mins holding at 1500ft above dest

If SCF not available contin is greater of
-5% trip
-5 mins holding at 1500ft above dest

Can be reduced under OMA 8.1.7.6.4

31
Q

What is statistical CONT95

A

Based on historical route data. 95% of the time the contingency fuel provided was enough for flight to land with Final reserve and alternate fuel in tact

32
Q

What is alternate fuel?

A

Fuel to fly a missed approach at destination airfield and then divert to alternate and fly approach and landing

If 2 alternates selected, fuel for the further away one

33
Q

What is final reserve fuel?

A

Fuel to fly for 30 minutes at 1500ft above destination alternate aerodrome in ISA conditions

34
Q

What is additional fuel and when is it provided?

A

Fuel to fly for 15 mins at 1500ft above aerodrome elevation
Provided when dispatched under ‘no destination alternate’ rules and on some routes where perf penalties exist

35
Q

What is extra fuel, when should it be carried and what is the penalty?

A

Extra fuel is carried at the discretion of the commander. It should be carried when there are sound operational or economic reasons for doing so e.g TX, LVPs, Icing, RWY closures, ATC delays etc.

Penalty for extra fuel is 3% of extra fuel per hour of flight

36
Q

What is the approximate fuel burn with anti-ice holding at 1500ft?

A

Holding - 400kg/min
Eng anti-ice - 2kg/min
Eng anti-ice + Wai - 3kg/min

OMB 5.1

37
Q

If tankering planned, what limits are placed on the fuel carried?

A

Tankering will be planned to within 1% of MTOW or MLW whichever is more limiting

38
Q

Regarding low fuel states what does ‘minimum fuel’ mean to ATC? What about mayday?

A

Minimum fuel - all other airfields options have been used up & any change to current clearance will result in landing below final reserve
Mayday - will land below final reserve

Approach fuel 17kg/min

39
Q

How long is a TEMPO on a TAF expected to last?

A

Not more than half the specified time frame and not more than 1 hour at a time

40
Q

Which documents are carried on board in paper form?
Which are in electronic format in the EFB?

A

Paper - Certificate of Airworthiness, Airworthiness Review certificate, Certificate of Regustration

Electronic - AOC, Noise, Radio licence, third party insurance certificate

41
Q

What is the difference between a level 1 & level 2 defect?

A

Level 1 - carries some form of operational limitation and affects airworthiness
Level 2 - less serious, does not affect airworthiness, mostly cosmetic issues like dirty carpets etc

42
Q

What is an ADD and who can transfer one to the aircraft status sheet?

A

Acceptable deferred defect, it means the aircraft is still airworthy with that defect. Dispatch can be made in accordance with MEL.

Usually transferred by a part 145 engineer but when downroute in non-maintenance base it is possible for captain to defer a defect under guidance of maintenance.

43
Q

What are the MEL repair intervals?

A

A - no interval specified but could be number of hours/cycles etc. condition of repair will be listed in MEL.
B - 3 days
C - 10 days
D - 120 days

44
Q

How long is a daily inspection valid?

A

48 hours plus the remaining part of the day of issue, if certified after 1800 UTC

45
Q

What are the wake turbulence timing intervals when departing behind a heavy and super heavy (A380)?

A

Heavy - same point on runway 2 mins, different intersection 3 mins

Super heavy (A380) - same point on runway 3 mins, different intersection 4 mins

Departing after A380 landing with displaced threshold - 3 mins

46
Q

On final approach, what is the minimum distance to be maintained behind a heavy & super heavy (A380) respectively?

A

Heavy - 5 miles
Super heavy (A380) - 7 miles but never less than 3 minutes

47
Q

What distance laterally and vertically should you avoid thunderstorm cells?

A

30000ft 20 NM
25000ft 15 NM
20000ft 10 NM

5000ft vertically
