100ft AGL

Question 7

What is the minimum height for use of the autopilot during all phases other than takeoff , instrument approach or go - around ?

Answer 7

320 - 500ft AGL

321 - 900ft AGL

Question 8

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

Answer 8

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

Question 9

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

Answer 9

Obstacle clearance and adherence to airspace constraints remains the flight crews responsibility

Question 10

What is the maximum wind conditions for CAT2 or CAT 3 ILS Automatic Approach, landing and Rollout?

Answer 10

HW 30 kts
XW 20 kts
TL 10 kts

320 Sharklets 
XW  15kts ( with auto rollout )

321
HW 40 CAT 2
30 CAT 3

XW 25 CAT 2
20 CAT 3

TW 10 kts

Note : wind limitation is based on the surface wind reported by the tower. If the wind displayed on the ND exceeds the above mentioned limitations, but the tower reported wind is within limitations, then the autopilot can remain engaged. If the tower now reports a surfacewind beyond limitations only CAT 1 automatic approach without auto land can be performed
Refer to RCAM xx-9EY for EY / state limitation

Question 11

What type of approach cannot be flown using FMGS lateral and Vertical Navigation mode ( FINAL APP) ?

Answer 11

ILS , LOC and LOC B/ C

Question 12

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

Answer 12

No. Etihad policy prohibits RNAV approaches without GPS PRIMARY

Question 13

What is the prerequisite for using NAV mode in the terminal area?

Answer 13

NAV mode maybe used in the terminal area provided
GPS primary is available or
HIGH accuracy is displayed and the appropriate RNP is checked or entered on the MCDU/MFD OR
NAVAID raw data is monitored

Question 14

What is the limitation regarding the use of autopilot to perform a Non-Precision Approach if one engine is inoperative?

Answer 14

No limitation

Question 15

What is the Alert Height during a CAT 3 Fail Operation ( Dual ) ILS automatic Approach?

Answer 15

100 ft

Question 16

What is the permissible flap/slat configuration for a CAT2/CAT3 ILS with one engine inoperative ?

Answer 16

320 CONF FULL

321 CONF 3 or FULL

Question 17

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

Answer 17

A321 During automatic rollout with one engine inop the remaining thrust reverser can be used provided that :
Only IDLE reverse thrust is used
The XW does not exceed 15 Kts

320 Sharlets
Only IDLE reverse thrust used
XW 15 kts for Auto Rollout

Question 18

What are the mandatory precautions that must be taken if performing an automatic landing in CaT 1 or better weather conditions ( Practice LVP Apprach autoland ?

Answer 18

Practice low vis approach and or autoland are only permitted on runways certified for LVP, with prior ATC coordination and assurance of protection against signal disturbance.

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

At least CAT2 capability is displayed on the FMA and CaT 2/3 procedures are used

Visual reference are obtained at an altitude appropriate to the performed CAT 1 approach otherwise a go around is initiated

Question 19

What is the aircraft approach Category?

Answer 19

320 CAT C

321 CAT D
