Q

List the stable approach criteria.

A

Non-circling approach:

“CRAP WS”
C - Checklist completed
R - Rate of descent
A - Angle of bank
P - Path (vertical + lateral)
W - Wheels down (configuration)
S - Speed

These criteria SHOULD be met by 1000ft. If they are not, the approach may continue to 500ft if there is a good probability that they will be met.

CHECKLIST COMPLETED
Landing checklist must be complete by 500ft.

RATE OF DESCENT
Commensurate with approach path and speed

ANGLE OF BANK
15° or less

PATH (vertical)
- < 1 dot deviation (ILS glideslope)
- < ¾ dot deviation (V/DEV bar)
- < 100ft from vertical profile (for 2D approach)
- PAPI indicators not showing 4 reds or 4 whites

PATH (lateral)
- < 1 dot deviation (ILS LLZ)
- < 0.3nm XTK if using FINAL APP (not RNP-AR)
- < RNP specification if performing RNP-AR approach
- 30° of FAT for visual or circling approaches.

WHEELS DOWN
Landing configuration must have been achieved by 1000ft

SPEED
By 1000ft, speed must be less than VAPP +30kt
By 500ft, speed must be +10kt/-5kt.

For a circling approach, all of the above must be achieved by 400ft and additionally, for AoB, when within 30° of the runway axis, it must be <15°.
The “stable/not stable” call for a circling approach must be referenced to 400ft above TDZE.

Q

What deviations on a 3D approach require a callout from the PM?

A

In FINAL APP mode: 0.1nm deviation requires “CROSSTRACK” callout and ½ dot vertical deviation requires “V-DEV” callout
In LOC & GS, deviation of ½ dot requires “LOC” or “GLIDE” callout.

Q

What is the difference between Net Take Off Flight Path and Gross Take Off Flight Path?

A

Gross Take Off Flight Path is that profile actually flown by an aircraft. The Net Take Off Flight Path is that required by regulation. Usually, NTOFP is lower than GTOFP.

Q

What are the climb gradient requirements applicable to approach and landing?

A

“Approach climb”, which must be 2.5% (or higher, if stated in the LIDO minima). This is based on the go around flaps configuration, one engine inoperative and TOGA thrust on the other engine, and landing gear up.
NB: FCOM states that go around climb gradient should be 2.1%. This is below the EASA limit of 2.5%
“Landing climb” is basically the balked landing performance. This must be 3.2%. This is based on 2 engines, landing configuration.

Q

When is a nav accuracy check required, and how do you do it?

A
  • When entering NAT HLA, if not GPS PRIMARY.
  • Prior to conducting an approach in FINAL APP mode
    It is done by simply checking that the PROG page displays, “NAV ACCUR HIGH”.

A
  • Hold on toe brakes

  • When groundspeed reaches 15kt, increase thrust to FLX/TOGA
  • Takeoff thrust to be achieved by 40kt groundspeed
  • Sidestick fully forward until airspeed reaches 80kt.

A
  • OAT or TAT <10°C & visible moisture (clouds or fog, visibility <1600m)
  • If SAT <-40°C, engine anti ice need not be selected on for climb & cruise, but should be selected on for descent.

30
Q

What callouts must be made during the approach for deviations?

A

For any parameter that will lead to an unstable approach.
Reminder: stable approach criteria are RPAWS:
- Rate of descent
- Path (localiser & glideslope, or track & path in FINAL APP mode)
- Angle of bank (& pitch angle)
- (Wheels down)
- Speed

So:
- “SINK RATE” if rate of descent >1000fpm
- “LOC”, “GLIDE”, “CROSSTRACK”, “V/DEV”, or “COURSE”
- “BANK” for bank angle >7°
- “PITCH” for pitch <2.5° or >10° (319/320)/7.5 (321)
- “SPEED” for speed +10kt or -5kt

31
Q

What callouts must be made by the PM during a go around if certain parameters are not met?

A
  • “BANK” for bank >7°
  • “PITCH” for pitch <10° or >20°
  • “SINK RATE” if no positive climb

21/10/24

32
Q

When can a flex take-off not be performed?

A
  • Contaminated runway
  • Dispatch is planned with landing gear extended (e.g., gear retraction inoperable).

21/10/24

33
Q

If 2 alternates are required, how much fuel should be loaded?

A

The larger amount (e.g., if alternate 1 requires 1.5T CNR and alternate 2 requires 1.3T, then the CNR applicable is 1.5T).

08/05/24

34
Q

On the OFP, alternate fuel is designated as “F” or “C”. Why?

A

“F” is a fuel alternate. This is chosen if a diversion is unlikely, considering weather conditions.
“C” is the commercial alternate is selected if a diversion is likely. Commercial alternates are numbered in terms of priority.

35
Q

What is the lowest system minima for a fail passive system?

A

DH: 50ft, RVR: 175m

08/05/24

36
Q

What is the maximum distance from an adequate aerodrome in the cruise?

What is its significance?

A

A319 - 380nm
A320 & A321 - 400nm

This is 1 hour’s flying at the one engine inoperative cruise speed (ISA, still air).

08/05/24

37
Q

Your departure airport is below the limits make an approach (but is still acceptable for departure). Discuss.

A

A take off alternate is required.

The take off alternate must be within 320nm (this is the OEI speed in ISA conditions and still air).

08/05/24

38
Q

What is the “missed approach climb gradient”?

A

If no MACG is specified, then 2.5% prevails.

Designing procedures is a highly specialised task that requires training and experience.

09/05/24

39
Q

What are the SOPs regarding brake temperatures at each phase of flight?

A

Taxi:
If arc is displayed over any brake temp (>100°C): put brake fans ON.

Before take off:
If brake fans have been used, temperature must be less than 150°C to take off.
Over 300°C: do not take off.

After landing:
Temp >500°C: brake fans ON without delay.
Otherwise, wait 5 mins before putting brake fans ON (unless turnaround time is short).

Parking:
Parking brake should be released after chocks in place if brake temp >500°C (brake fans off) or temp >350°C (brake fans on).

A

+10

42
Q

When should Vapp be modified in normal operations?

A
  • Vapp may be increased to a maximum of Vls+15kt if winds are strong/gusty and the crosswind component is >20kt.
    (If doing this, check landing performance)
  • When on approach, if Vapp is less than Vls+3, then Vapp should be corrected to Vapp+5.
