What are the required ceiling and visibility minima for a helicopter to select a destination alternate aerodrome that has an instrument approach procedure (IAP), during daytime?

For an alternate aerodrome with an IAP, the ceiling must be at least 200 ft above the DH or MDH associated with the IAP, and the visibility must be at least 1 500 m by day.

If a helicopter is selecting a destination alternate aerodrome with an IAP and the DH is 500 ft, what is the minimum ceiling required?

The ceiling must be at least 200 ft above the DH, so for a DH of 500 ft, the minimum ceiling is 700 ft.

What is the minimum visibility required for a helicopter destination alternate aerodrome without an IAP during daytime?

The visibility must be at least 1 500 m by day.

For a helicopter destination alternate aerodrome with an IAP, what is the minimum visibility required at night?

The visibility must be at least 3 000 m by night.

What regulation establishes the destination alternate aerodrome planning minima for helicopters?

Regulation (EU) 2021/2237 establishes these minima.

SPO.OP.144 Destination alternate aerodrome planning minima -- helicopters

Q: For a helicopter destination alternate aerodrome without an IAP, what ceiling and visibility values must be met for night operations?

For an alternate aerodrome without an IAP, the ceiling must be at least 2 000 ft or the minimum safe IFR height, whichever is greater, and the visibility must be at least 3 000 m by night.

Q: Over what time period must current meteorological information indicate that the destination alternate aerodrome minima are met for a helicopter operation?

The meteorological information must indicate the minima are met for the period from 1 hour before until 1 hour after the estimated time of arrival, or from the actual time of departure to 1 hour after the estimated time of arrival, whichever is the shorter period.

Q: When selecting a destination alternate aerodrome without an IAP, how is the required ceiling determined?

The ceiling must be at least 2 000 ft or the minimum safe IFR height, whichever is greater.

SPO.OP.144 Destination alternate aerodrome planning minima — helicopters

Regulation (EU) 2021/2237

The operator shall only select an aerodrome as a destination alternate aerodrome if the available current meteorological information indicates, for the period from 1 hour before until 1 hour after the estimated time of arrival, or from the actual time of departure to 1 hour after the estimated time of arrival, whichever is the shorter period,

(a) for an alternate aerodrome with an IAP:

(1) a ceiling of at least 200 ft above the DH or MDH associated with the IAP; and

(2) a visibility of at least 1 500 m by day or 3 000 m by night; or

(b) for an alternate aerodrome without an IAP:

(1) a ceiling of at least 2 000 ft or the minimum safe IFR height, whichever is greater; and

(2) a visibility of at least 1 500 m by day or 3 000 m by night.
