What are the destination alternate aerodrome planning minima for an aeroplane when the available instrument approach operation has a DH of less than 250 ft?

For an alternate aerodrome with an available instrument approach operation with DH less than 250 ft, the ceiling must be at least 200 ft above the DH or MDH, and the visibility must be at least the higher of 1 500 m and 800 m above the instrument approach operation RVR/VIS minima.

If a destination alternate aerodrome has an instrument approach operation with a DH or MDH of 250 ft or more, what ceiling and visibility minima apply?

For an alternate aerodrome with an instrument approach operation with DH or MDH 250 ft or more, the ceiling must be at least 400 ft above the DH or MDH, and the visibility must be at least 3 000 m.

What are the planning minima for a destination alternate aerodrome that has no instrument approach procedure?

For an alternate aerodrome without an instrument approach procedure, the ceiling must be at least the higher of 2 000 ft and the minimum safe IFR height, and the visibility must be at least 5 000 m.

If a destination alternate aerodrome has an instrument approach with a DH of 300 ft, what is the required ceiling?

For an instrument approach operation with DH or MDH 250 ft or more, the ceiling must be at least 400 ft above the DH or MDH. Therefore, for a DH of 300 ft, the ceiling must be at least 700 ft.

What is the minimum visibility for a destination alternate aerodrome without an instrument approach procedure if the minimum safe IFR height is 1 500 ft?

For an alternate aerodrome without an instrument approach procedure, the visibility must be at least 5 000 m, regardless of the minimum safe IFR height.

For a destination alternate aerodrome with an instrument approach operation having a DH of 200 ft, what is the minimum ceiling requirement?

For an instrument approach operation with DH less than 250 ft, the ceiling must be at least 200 ft above the DH or MDH. Therefore, for a DH of 200 ft, the ceiling must be at least 400 ft.

Q: For which time period must the available current meteorological information indicate the required conditions for a destination alternate aerodrome?

The meteorological information must indicate the required conditions 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.

Regulation (EU) 2021/2237

An aerodrome shall not be specified as a destination alternate aerodrome unless 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 available instrument approach operation with DH less than 250 ft,

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

(2) a visibility of at least the higher of 1 500 m and 800 m above the instrument approach operation RVR/VIS minima; or

(b) for an alternate aerodrome with an instrument approach operation with DH or MDH 250 ft or more,

(1) a ceiling of at least 400 ft above the DH or MDH associated with the instrument approach operation; and

(2) a visibility of at least 3 000 m; or

(1) a ceiling of at least the higher of 2 000 ft and the minimum safe IFR height; and

(2) a visibility of at least 5 000 m.
