Visual Approach and AIP ENR 1.14.a(3)

[FRQ Charlie Bravo]

Hi all,

AIP ENR 1.14.a(3) states that a visual approach may be commenced when certain criteria are met including:

(3) with a flight visibility not less than 5,000M or, in the case
of a helicopter, is able to proceed under helicopter VMC,
or the aerodrome is in sight...

In the case of an aeroplane does that last part apply or is that part of the helicopter bit? i.e. can an aeroplane pilot continue with visibility of less than 5,000M but with the aerodrome in sight?

Clarification

Allow me to rephrase. Would the paragraph mean the same thing if instead of saying:

with a flight visibility not less than 5,000M or, in the case
of a helicopter, is able to proceed under helicopter VMC,
or the aerodrome is in sight

it said:

with a flight visibility not less than 5,000M or, in the case
of a helicopter, is able to proceed under helicopter VMC,
or, in the case of a helicopter, the aerodrome is in sight

or would that change the meaning altogether?

Is how i'm reading it.
Vis not less than 5,000M (or helicopter VMC) or Aerodrome in sight.

In Flight Visibility

In reality, In-Flight Visibility (IFV) would need to be taken into account. IFV is the visibilty required to maintain sight of the airport in a rate 1 turn. This is assumed to be 3000 metres. To calculate required in-flight visibilty , multiply the aircraft's manoeuvring speed in knots by 20 e.g 150 kt x 20 = 3000 metres in-flight visibilty.

In-Flight Visibility? Never heard of that one before. Is that an ICAO thing or some wierd regional rule?

IFV was used in the French Pacific Overseas Territories.
