1.18.1.6 Approaches in low-visibility conditions and approach and runway lighting

It was considered that this shallow approach slope could have exacerbated the previously-identified risk of visual illusion due to the lack of approach lighting and the wet runway.

Runway 15 was equipped with AN type approach lighting (see Figure 3), and did not have touchdown zone or runway centre line lighting.

8.5.1.6 Standard.—Approach lighting shall be operated at night or in daytime IMC conditions for an arriving aircraft;

RVR for non-precision approach — Nil approach light facilities

RVR for non-precision approach — Nil approach light facilities

In particular, Air Canada has established standards regarding approach and runway lighting required for approaches under such conditions.

The controller had assessed the visibility as higher than reported by the automatic weather observation system and, therefore, did not turn on the approach lighting.

If a network communication problem means a major airport cannot control the approach and runway lighting, the airport may be forced to delay or divert the flights.

Furthermore, the company has not set any requirements regarding approach or runway lighting when daytime visibility is greater than ¾ sm (RVR of 4000 feet).

Aéroports de Montréal (ADM), in consultation with NAV CANADA, reviewed their operating agreement regarding approach and runway lighting, particularly with respect to conditions for closing a runway.
