Question 10

What approach types cannot be flown using FMGS Lateral and Vertical Navigation Mode (FINAL APP)?

Answer 10

ILS, LOC and LOC B/C

Question 11

Is it authorized to fly a RNAV approach without GPS PRIMARY?

Answer 11

No. Etihad policy prohibits RNAV approaches without GPS PRIMARY.

Question 12

What are the pre-requisites for using NAV mode in the terminal area?

Answer 12

NAV mode may be used in terminal area provided that:
‐ GPS PRIMARY is available, or
‐ the appropriate RNP is checked or entered on the MCDU, and HIGH accuracy is displayed, or
‐ FMS navigation is crosschecked with navaid raw data

Question 13

What is the applicable Alert Height during a CAT 3 Fail Operational (Dual) ILS Automatic Approach?

Answer 13

100 ft.

Question 14

What are the permissible flap/slat configurations for a CAT 2/CAT 3 ILS with One Engine Inoperative?

Answer 14

A320
CONF FULL
A321
CONF 3 or
FULL

Question 15

What are the specific limitations applicable to automatic landings in regards to engine out procedures?

Answer 15

A321
During automatic rollout with one Eng. Inop., the remaining thrust reverser can be used provided that:
- Only IDLE reverse thrust is used
- The XW does not exceed 15 Kts
A320 Sharklets:
- Only IDLE reverse thrust is used
- XW 15 Kts for Auto Rollout
XW 20 Kts without AUTO ROLLOUT

Question 16

What are the mandatory precautions that must be taken if performing an automatic landing in CAT 1 or better weather conditions (Practice LVP Approach/Autoland)?

Answer 16

1. Practice low visibility approaches and/or autoland are only permitted on runways certified for LVP, with prior ATC coordination and assurance of protection against signal disturbance. (OM-A 8.4.12).
2. The crew is aware that LOC or GS beam fluctuations, independent of aircraft systems, may occur and the PF is prepared to immediately disconnect the AP and take appropriate action, should unsatisfactory guidance occur.
3. At least CAT 2 capability is displayed on the FMA, and CAT 2/CAT 3 procedures are used.
4. Visual references are obtained at an altitude appropriate to the performed CAT 1 approach, otherwise a go-around is initiated.

Question 17

What is the aircraft approach Category? (OM-A 8.1)

Answer 17

A320: CAT C
A321: CAT D
