61
Q

What is the approach ban?

Can you start an approach with the RVR’s below limits?

A

An instrument approach may be commenced regardless of the reported RVR/VIS. If the reported RVR/VIS is less than the applicable minimum the approach shall not be continued:

  1. Below 1000 ft above the aerodrome; or
  2. Into the final approach segment in the case where the DA/H or MDA/H is more than 1000 ft above the aerodrome.

Where the RVR is not available, RVR values may be derived by converting the reported visibility in accordance with Part A Section 8.1.3.4.

If, after passing 1000 ft above the aerodrome, the reported RVR/VIS falls below the applicable minimum, the approach may be continued to DA/H or MDA/H.

OMA 8.4.3

62
Q

You are flying an approach in LVP’s, you have some kind of failure at 2000ft. Can you continue? When must you go around?

A

As a general rule, if a failure occurs above 1,000 ft above TDZE the approach may be continued reverting to a higher DH, providing the appropriate conditions are met.

Above 1,000 ft above TDZE: Downgrading conditions:

Downgrading from is permitted only if:

ECAM (check-list) actions are completed.
RVR is at least equal to required minima.
Briefing is amended to include relevant procedure and DH.
Decision to downgrade is completed above 1,000 ft above TDZE.

OMB

63
Q

What must you go around for below 1000ft in LVPs?

A

Below 1,000 ft above TDZE and above DH (for CAT II or CAT III SINGLE) or above AH (for CAT III DUAL).

A go-around must be performed in case of:

ALPHA FLOOR activation.
Loss of AP (cavalry charge).
Downgrading of capability (triple click).
Amber caution (single chime).
Engine failure.

OMB 2.3.18.3.1

64
Q

On an LVP approach below 1000ft explain what happens to the aircraft? (eg what happens at 800ft, 350ft, 200ft, 100ft
etc…)

A

At 350 ft RA (*).

LAND must be displayed on FMA and runway course must be checked.
If runway course is incorrect or LAND does not appear, a go-around must be performed.

LAND is displayed if LOC and GS track modes are active and at least one RA is available. These conditions need to be obtained no later than 350 ft AGL to allow a satisfactory automatic landing.

(*) Depending on terrain profile before the runway LAND mode may appear at lower height. This can be acceptable provided it has been demonstrated that automatic landing is satisfactory.

At 200 ft RA and below.
Any AUTOLAND warning requires an immediate go-around.

If visual references are sufficient and a manual landing is possible, the PF may decide to land manually.

At flare height.
If FLARE does not come up on FMA, a go-around must be performed.
If visual references are sufficient and a manual landing is possible, the PF may decide to complete the landing.

After touchdown.

In case of anti-skid or nose wheel steering failure, disconnect AP and take manual control.
If automatic roll-out control is not satisfactory, disconnect the AP immediately.

65
Q

What causes the activation of the AUTOLAND light?

A

The AUTOLAND warning flashes when:

At least one RA indicates a height below 200 ft, and
At least one AP is engaged with LAND or FLARE mode on the FMA, and
At least one of the following conditions occurs:

The LOC deviation exceeds ¼ dot and the aircraft is above 15 ft RA (the LOC scale flashes on the PFD), or

The GLIDE deviation exceeds 1 dot and the aircraft is above 100 ft RA (the GLIDE scale flashes on the PFD), or

Loss of LOC signal above 15 ft RA (the FD vertical bar flashes on the PFD), or

Loss of GLIDE signal above 100 ft RA (the FD horizontal bar flashes on the PFD), or

The difference between both RA indications is greater than 15 ft RA , or

The last autopilot disengages.

OMB 2.3.18.3.1
And (on newer models):

The FMGS detects a long flare, or
The FMGS detects an untimely Flare condition.
