APPROACHES

Question 1

Define an OTS CAT II Approach?

Answer 1

• A Category II​ Instrument​ Approach and ​ ​Landing​ Operation to a​ runway​ where​ some or​ all​ of​ the elements of​ the​ ICAO​ Annex 14​ ​ ​Precision​ Approach Category​ II​ lighting system are​ not​ available.​

(NOR 8.4.1.2 page 6)

Question 2

What is the call of the captain during a CAT III Approach when arming the second autopilot?

Answer 2

“Second​ Autopilot​ Armed”​ when dual CMD is​ ​verified on the MCP​.

(NOR OM.B 2.1.2.17) (08/2022)

Question 3

On a CAT III Approach, what is the call of the PM during the flare and retard?

Answer 3

“Negative​ ​Flare”​ if​ flare is​ not​ announced​ at​ 50 ​ft.​ ​​ “Negative​ ​Retard”​ if​ retard is​ not​ announced​ at​ ​27 ft.
We do not call out “Flare” and “Retard” anymore.

(NOR OM.B 2.1.2.12) (08/2022)

Question 4

On a RNP and RNP AR Approach, when we do the altimeter crosscheck at the FAF, what is the max difference between altimeters?

Answer 4

Max 100 feet difference.

(OM B 2.9.14.8)

Question 5

What is the max deviation from the vertical path with a RNP/RNP AR approach?

Answer 5

+/-75 feet.
We need to insert 125 feet for vertical RNP in the FMC, this will cause the NPS Amber deviation exceedance alert to occur at 75 feet or slightly less deviation, since vertical ANP will be at least 50 feet at all times.

(NOR OM B 2.19.14.8)

Question 6

What are the minimums (RVR and DH) for a OTS CAT II approach according to the company minimums?

Answer 6

RVR 450 m, DH 100ft.
See Certificates and Approvals

Question 7

Can we do LTS CAT I Approaches in any norwegian AOC

Answer 7

Yes, norwegian has 1 aircraft in the Norwegian Air Norway AOC where it is allowed to do this approach.

See NAN Certificates and Approvals.

Question 8

What does TAA stands for on a approach plate?

Answer 8

Terminal Arrival Altitude.

Question 9

When and where do we need to insert 125 feet for vertical RNP when doing a RNP APCH or RNP AR APCH?

Answer 9

When the altimeters are set to QNH and before the IAF, or the start of radar vectors to the final approach course.

(NOR OM B 2.9.14.8)

Question 10

What is the lateral RNP (Required Navigation Performance) for a RNP and RNP AR approach?

Answer 10

RNP approach: 0,3 NM
RNP AR approach: 0,3-0,1NM

(NOR OM B 2.9.14.9)

Question 11

On a RNP or RNP AR approach, from which deflection on the lateral NPS should we executed a go-around?

Answer 11

After passing the FAF, exceeding half scale deflection (0.5 x RNPx) on the lateral NPS for a RNP approach. Full deflection on a RNP-AR approach (1xRNPx)

(NOR OM B 2.9.14.9)

Question 12

During a RNP or RNP AR Approach, who selects VOR UPDATE - OFF and enters 125 feet for vertical RNP?

Answer 12

Pilot Monitoring

(NOR OM B 2.9.14.8)

Question 13

When is a RNP APCH a 2D instrument approach and when is it a 3D instrument approach?

Answer 13

• 2D when we operate down to LNAV minima.
• 3D when we operate down to LNAV/VNAV minima.

(EASA AIRCREW page 63)

Question 14

What is a 2D instrument approach procedure?

Answer 14

A ‘Two-dimensional’ approach means an instrument approach operation using LATERAL navigation guidance only.
- for instance: a RNP approach to LNAV minima, VOR approach

Question 15

What is the max lateral deviation on a CAT III Approach?

Answer 15

Max 1 dot deflection from localizer and below 300ft. the approach must be flown within the expanded localizer band.
(OM A 8.3.24)

Question 16

How to fly an approach in ‘windsheary’ conditions?

Answer 16

Disconnect the autopilot and autothrottle and trade altitude for airspeed, don’t control the airspeed with with only the thrust levers and trying to stay on the glide. If the speed drops push nose down, if speed increases pull nose up.

(Line check with Bjørn Kluver)

Question 17

What are the standard speeds during final approach?

Answer 17

180 kts until 6 NM and 160 kts until 4 NM.

Question 18

Explain the deviation of the Expanded Localizer scale.

Answer 18

Deviation is slightly more than 1/2 dot AND track is within 5 degrees of the MCP selected course.
(FCOM 10.11.26)

Question 19

When will the A/C transition to “on approach” logic?

Answer 19

• 2 NM of first approach waypoint
• 2000 ft of airport elevation

Question 20

When performing a CDFA, what is the Callout of the PM when checking the Altitude Vs the Distance?

Answer 20

“On Profile” when the deviation is +-50ft.
“XXX feet High/Low” when the deviation is more than 50ft.
(OM A 8.4.10.9)

Question 21

When performing a CDFA, when should we do a GO-AROUND?

Answer 21

When we are 150 feet below the path.
(OM A 8.4.10.8)

Question 22

• When should we crosscheck altimeters when performing a Baro-VNAV (RNP with LNAV/VNAV minima or RNP-AR)?
• What is the maximum difference between primary altimeters?

Answer 22

• Crosscheck should be done LATEST at the FAF.
• Max difference is 100 ft.
