OMB Flashcards
List the stable approach criteria.
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.
What deviations on a 3D approach require a callout from the PM?
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.
28/09/24
Excessive vertical deviations on approach must be called out when (for FINAL APP and ILS)
What are the FO handling limitations?
ACCCTW 345
Autoland: no autoland
Crosswind: max 20kt
Contaminated: no RWYCC 4 or lower
Cat 1: weather must be CAT1 or better
Tailwind: no planned tailwinds for 3 star FOs.
Windshear: no reported windshear
3 - Flaps 3: 3 star FOs may not use Flaps 3
4 - 45m: unless specific training has been completed.
5 - RVR 550m

What are the segments of the NTOFP?
First segment: from screen height to gear retraction (at V2)
Second segment: start of flap retraction
Third segment: acceleration and completion of flap retraction
Fourth segment: to 1500ft.
25/09/24
What are the climb requirements for each segment of take off?
Net Take Off Flight Path requires:
Second segment: 2.4%
Fourth segment: 1.2%
25/09/24
What is the difference between Net Take Off Flight Path and Gross Take Off Flight Path?
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.
25/09/24
What are the climb gradient requirements applicable to approach and landing?
“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.
25/09/24
What is the fuel penalty for loading extra fuel?
3% per tonne per hour of flight.
09/10/24
When is a nav accuracy check required, and how do you do it?
- 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”.
09/10/24
If nav accuracy is low, what do you do?
- Don’t use TERR on ND
- If using FINAL APP mode, use TRK FPA to reference the approach final course tracking to raw navaid data.
Runway has standing water… what should you do?
(assuming performance has been calculated approriately)
Engine mode sel - IGN
09/10/24
Flying through heavy rain or if severe turbulence is expected after take off. What is one thing that needs to be selected?
Eng mode sel - IGN
09/10/24
Describe a take off in crosswind exceeding 20kt, or a tailwind.
- Hold on toe brakes
- Sidestick fully forward
- Set 50% N1
- Release brakes
- Increase thrust to 70%
- When groundspeed reaches 15kt, increase thrust to FLX/TOGA
- Takeoff thrust to be achieved by 40kt groundspeed
- Sidestick fully forward until airspeed reaches 80kt.
27/10/24
Describe “icing conditions”.
- 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.
01/11/24
How should the weather radar be set for departure?
What are the calls to the cabin crew for an emergency landing?
