Define “Fail Passive”

Fail Passive is when in the event of a failure, there is no significant out-of-trim condition or deviation of flight path or attitude but the landing is not completed automatically

How is “Fail Passive” capability announced on the A320?

“CAT 3 SINGLE” on the PFD

Define “Fail Operational”

Fail Operational is when in the event of a failure below alert height, the approach, flare and landing can be completed by the remaining part of the automatic system. In event of a failure, the automatic landing system will operate as a fail-passive sytem

Define “Alert Height”

Height above the runway above which a CAT III approach would be discontinued, and a missed approach initiated if a failure occurred in one of the relevant parts of the auto-land system
When a failure occurs below AH, the system ignores it and the approach can be continued

What does the implementation of LVP/SSP procedures ensure?

What is the light configuration for RETILs (Rapid Exit Taxiway Indicator Lights)?

6 Yellow lights adjacent to the centerline in a 3/2/1 pattern spaced 100m apart, the single light is 100m from the start of turn to the exit.
60m before the start of the turn the lights become alternating Yellow and Green

Can we use FLEX takeoff for a LVTO?

Study These Flashcards

No, has to be TOGA

What is the benefit of using TOGA instead of FLEX for a LVTO?

Study These Flashcards

TOGA generally results in lower takeoff speeds

What LVTO RVR is HKE currently approved for?

RVR 150 - 300m RVR depending on state. Check table

Below what altitude is the Yaw Bar displayed on take-off?

Below 30 ft RA

Define "Decision Height"

The Wheel Height above the runway by which a Go-Around must be initiated, unless adequate visual reference have been established

What DH should be used on a CAT II approach: Chart minima or HKE minima?

When a higher minima is on the chart, it should be used

If no DH is published for a CAT II/III approach on a approach chart, what minima should be used?

HKE approved minima

What are the visual requirements at DH for a CAT IIIB approach?

1 Centerline light

What are the visual requirements at DH for a CAT IIIA approach?

3 Consecutive lights Centerline of approach lights or Touchdown zone lights or Runway Centerline lights or Runway Edge lights or a combination of all these

What are the visual requirements at DH for a CAT II approach?

3 Consecutive lights Centerline of approach lights or Touchdown zone lights or Runway Centerline lights or Runway Edge lights or a combination of all these BUT It must include a lateral element of the ground pattern to establish lateral position and cross-track velocity

On a LVO approach, what is DH referenced to?

Radio Altimeter

When is the AUTOLAND red light warning triggered for LVO approaches?

Below 200 ft RA in LAND or FLARE mode

What triggers the AUTOLAND red light warning triggered for LVO approaches?

- Autopilots are lost - 1/4 dot LOC deviation above 15 ft RA - 1 dot G/S deviation above 100 ft RA - Loss of LOC signals above 15 ft RA - Loss of G/S signal above 100 ft RA - Difference between both RA:s are greater than 15 ft

When can you revert to higher minima on a LVO approach?

Only above 1000 ft

What failures shall trigger a go-around on a LVO approach?

- ILS course not displayed or incorrect - No "LAND" indication on the FMA - AUTOLAND warning light - No "FLARE" indication on the FMA - Long Flare detected

What is the HKE recommended Flap configuration for LVO approaches?

Conf FULL

How can you satisfy yourself that LVO are in force before conducting an LVO approach?

Could be on ATIS Clearance for an CAT II/III approach satisfy that

What are your first actions after a rejected T/O in LVO conditions?

Put all lights ON

Which lights should be switched off on final approach when doing an LVO approach?

STROBES TURN OFF LAND and NOSE lights

Describe PM:s actions and callouts on an LVO approach?

Below 400 ft: - Check flight path and Autoflight modes and - Call deviations Monitor: "ONE HUNDRED ABOVE" "MINIMUM" at DH Call: "FLARE" at 50-40 ft "IDLE" at 30 ft, if no auto call out "ROLL OUT" "SPOILERS" "REVERSE GREEN" "DECEL" "70 KTS"

At what height is the "RETARD" call generated on a LVO approach?

10 ft RA

Who has to be PF when conducting an Autoland?

CM 1, except in an emergency

By what altitude does the autopilot have to be disconnected, on a CAT II approach, for a manual landing?

By 80 ft

What are the HW, XW and TW limitations for a CAT III approach?

30, 20, 10

Do we need AUTOLAND on a CAT II Approach?

YES

Do we need AUTOLAND on a CAT III Approach?

YES

Do we need AUTOTHRUST on a CAT III Approach?

YES

Do we need AUTO ROLL-OUT on a CAT II Approach?

Do we need AUTO ROLL-OUT on a CAT III Approach?

YES

Can we do a manual landing from a CAT II Approach?

Yes

Can we do a manual landing from a CAT III Approach?

What is the Glideslope angle limitations for an AUTOLAND?

-2,5 to 3,15 deg

What is the maximum airport elevation for an Autoland in B-HSN?

6500 ft
