Question 6

What is the general limitation regarding the use of the autopilot and/or the FD during an approach in OPEN DES or DES mode?

Answer 6

The AP or FD in OPEN DES or DES mode can be used in the approach. However, its use is ONLY permitted if the FCU selected altitude is set to, or above, the higher of the two: MDA/MDH or 500 ft AGL

Question 7

What is the general limitation/precaution
regarding obstacle clearance and constraints programmed into the FMGS?

Answer 7

Obstacle clearance and adherence to airspace constraints remains the flight crew’s responsibility.

HW: 30 kt
TW: 10 kt
XW: 20 kt
A320-Sharklets
XW: 15 kt
(With Auto Rollout)
A321 CEO
HW: 30 kt (with Automatic Landing and Rollout)
TW: 10 kt
XW: 20 kt (with Automatic Landing and Rollout)
A321 NEO
HW: 15 kt
TW: 10 kt

Question 9

What is the minimum height for use of the autopilot during an ILS Approach with
CAT1 displayed on the FMA?

Answer 9

160 ft

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 authoriszed to fly a non-precision
approach in FLS mode?

Answer 11

No. FLS guidance mode is PROHIBITED for all non-precision approaches. FINAL APP shall always be selected in the MCDU PERF APPR PAGE when a non-precision approach is inserted in the F-PLN page.

Question 12

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

Answer 12

No. FCOM/PRO/SPO/PBN requires at least 1 GPS to start a RNAV approach (new PBN chart naming RNP APCH).

Question 13

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

Answer 13

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 14

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

Answer 14

100 ft

Question 15

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

Answer 15

A320
CONF FULL
A321
CONF 3 or
FULL

Question 16

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

Answer 16

A321ceo :
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 kt
A320 Sharklets:
- Only IDLE reverse thrust is used
- XW 15 kt for Auto Rollout
- XW 20 kt without AUTO ROLLOUT
A321neo :
- Only IDLE reverse thrust is used
- XW 10 kt

Question 17

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 17

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 18

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

Answer 18

A320: CAT C
A321: CAT D
