What should a pilot do if a ground aid failure is announced after passing 1000 feet above the aerodrome during an approach?

If failures of ground aids are announced after passing 1 000 ft above the aerodrome, the approach could be continued at the pilot-in-command's discretion.

When must a pilot consider abandoning an approach due to ground equipment failures?

If failures of ground aids are announced before the late stage (i.e., before passing 1 000 ft above the aerodrome), their effect on the approach should be considered as described in Table 15 and, if considered necessary, the approach should be abandoned.

What is the effect of a failed ILS outer marker on an APV approach?

For APV approaches, the outer marker is not applicable, so a failed outer marker has no effect on APV landing minima.

Under what condition does a failed outer marker have no effect on an ILS approach?

A failed outer marker has no effect on an ILS approach if the required height or glide path can be checked using other means, e.g., a DME fix.

Can an NPA operation be conducted if the FAF cannot be identified due to a failed outer marker?

No, if the FAF cannot be identified (e.g., no method available for timing of descent), NPA operations cannot be conducted.

What is the effect of a failed middle marker on an ILS approach when it is used as the MAPt?

If the middle marker is used as the missed approach point (MAPt), a failed middle marker means the approach cannot be conducted (no effect unless used as MAPt, but if used, operations cannot be conducted).

What is the effect of a failed RVR assessment system on landing minima?

A failed RVR assessment system has no effect on landing minima.

If approach lights are completely failed, what landing minima should be applied?

If approach lights are completely failed, the landing minima should be as for NALS (Non-Approach Light System).

What landing minima apply when approach lights are available except the last 210 metres?

When approach lights are available except the last 210 m, the landing minima should be as for BALS (Basic Approach Light System).

What landing minima apply when approach lights are available except the last 420 metres?

When approach lights are available except the last 420 m, the landing minima should be as for IALS (Intermediate Approach Light System).

What is the effect of a failure of standby power for approach lights on landing minima?

A failure of standby power for approach lights has no effect on landing minima.

What are the landing minima for a night landing if edge lights, threshold lights, or runway end lights fail?

For night operations, if edge lights, threshold lights, or runway end lights fail, landing is not allowed.

For aeroplanes, what is the effect of failed centre line lights on landing minima if the aircraft has a flight director (F/D), HUDLS, or auto-land?

For aeroplanes, failed centre line lights have no effect on landing minima if the aircraft has a flight director (F/D), HUDLS, or auto-land; otherwise, the RVR is 750 m.

For helicopters, what is the effect of failed centre line lights on CAT I and SA CAT I approach operations?

For helicopters, failed centre line lights have no effect on CAT I and SA CAT I approach operations.

What is the effect of increased centre line light spacing to 30 metres on landing minima?

Increased centre line light spacing to 30 m has no effect on landing minima.

For aeroplanes without F/D, HUDLS, or auto-land, what is the effect of failed TDZ lights on landing minima?

For aeroplanes without F/D, HUDLS, or auto-land, failed TDZ lights require an RVR of 750 m.

What is the effect of a failed taxiway lighting system on landing minima?

A failed taxiway lighting system has no effect on landing minima.

What is the effect of a failed navaid standby transmitter on landing minima?

A failed navaid standby transmitter has no effect on landing minima.

Q: Are simultaneous failures of approach lights and runway/FATO lights allowed, and how should they be handled?

Yes, failures of approach and runway/FATO lights are acceptable at the same time, and the most demanding consequence should be applied.

ED Decision 2022/014/R

EFFECT ON LANDING MINIMA OF TEMPORARILY FAILED OR DOWNGRADED GROUND EQUIPMENT

(a) General

These instructions are intended for both pre-flight and in-flight use. It is, however, not expected that the pilot-in-command would consult such instructions after passing 1 000 ft above the aerodrome. If failures of ground aids are announced at such a late stage, the approach could be continued at the pilot-in-command’s discretion. If failures are announced before such a late stage in the approach, their effect on the approach should be considered as described in Table 15 and, if considered necessary, the approach should be abandoned.

(b) Conditions applicable to Table 15:

(1) multiple failures of runway/FATO lights other than those indicated in Table 15 should not be acceptable;

(2) failures of approach and runway/FATO lights are acceptable at the same time, and the most demanding consequence should be applied; and

(3) failures other than ILS, GLS, or MLS affect RVR only and not DH.
