For IFR helicopter flights, what is the minimum number of weather-permissible destination alternate aerodromes that the pilot-in-command must specify in the flight plan?

At least one weather-permissible destination alternate aerodrome must be specified in the flight plan for IFR flights, unless the conditions in (a) or (b) of NCC.OP.152 are met.

What are the specific cloud base and visibility margins above the instrument approach procedure minima required for a helicopter to omit a destination alternate under the isolated aerodrome provision?

The cloud base must be at least 120 m (400 ft) above the minimum associated with the instrument approach procedure, and visibility must be at least 1 500 m more than the minimum associated with the procedure.

Under the isolated aerodrome exception in NCC.OP.152, what time window must the current meteorological information cover for the cloud base and visibility conditions?

The meteorological conditions must exist from 2 hours before to 2 hours after the estimated time of arrival.

For a helicopter IFR flight to an isolated aerodrome, what two requirements must be met regarding the instrument approach procedure and the meteorological information to avoid specifying a destination alternate?

An instrument approach procedure must be prescribed for the aerodrome of intended landing, and available current meteorological information must indicate the specified cloud base and visibility conditions will exist from 2 hours before to 2 hours after the estimated time of arrival.

NCC.OP.152 Destination alternate aerodromes

Q: Under NCC.OP.152, what are the two meteorological conditions that must be forecast to exist for the destination aerodrome to avoid specifying a destination alternate, when an instrument approach procedure is prescribed?

The two conditions are: (1) a cloud base of at least 120 m (400 ft) above the minimum associated with the instrument approach procedure; and (2) visibility of at least 1 500 m more than the minimum associated with the procedure.

NCC.OP.152 Destination alternate aerodromes – helicopters

Regulation (EU) 2016/1199

For IFR flights, the pilot-in-command shall specify at least one weather-permissible destination alternate in the flight plan, unless:

(a) an instrument approach procedure is prescribed for the aerodrome of intended landing and the available current meteorological information indicates that the following meteorological conditions will exist from 2 hours before to 2 hours after the estimated time of arrival, or from the actual time of departure to 2 hours after the estimated time of arrival, whichever is the shorter period:

(1) a cloud base of at least 120 m (400 ft) above the minimum associated with the instrument approach procedure; and

(2) visibility of at least 1 500 m more than the minimum associated with the procedure; or

(b) the place of intended landing is isolated and:

(1) an instrument approach procedure is prescribed for the aerodrome of intended landing;

(2) available current meteorological information indicates that the following meteorological conditions will exist from 2 hours before to 2 hours after the estimated time of arrival:

(i) the cloud base is at least 120 m (400 ft) above the minimum associated with the instrument approach procedure;

(ii) visibility is at least 1 500 m more than the minimum associated with the procedure.
