For IFR 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.

What are the two conditions that must be met for a destination alternate aerodrome to be omitted when the place of intended landing is an isolated aerodrome?

The two conditions are: (1) an instrument approach procedure is prescribed for the aerodrome of intended landing; and (2) available current meteorological information indicates that both specified 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.

For an isolated aerodrome, what cloud base and visibility minima must be forecast to exist for the period from 2 hours before to 2 hours after the estimated time of arrival?

The cloud base must be at least 300 m (1 000 ft) above the minimum associated with the instrument approach procedure, and visibility must be at least 5,5 km or 4 km more than the minimum associated with the procedure.

When evaluating whether a destination alternate aerodrome is required, what is the time window used for the meteorological information if the actual time of departure is later than 1 hour before the estimated time of arrival?

The time window is from the actual time of departure to 1 hour after the estimated time of arrival, whichever is the shorter period compared to the period from 1 hour before to 1 hour after the estimated time of arrival.

For an isolated aerodrome, what is the time window for the meteorological conditions if the actual time of departure is later than 2 hours before the estimated time of arrival?

The time window is from the actual time of departure to 2 hours after the estimated time of arrival, whichever is the shorter period compared to the period from 2 hours before to 2 hours after the estimated time of arrival.

Q: Under what meteorological condition can a pilot-in-command avoid specifying a destination alternate aerodrome for an IFR flight?

A destination alternate aerodrome is not required if the available current meteorological information indicates that, 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, the approach and landing may be made under visual meteorological conditions (VMC).

Regulation (EU) 2021/1296

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

(a) the available current meteorological information indicates that, 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, the approach and landing may be made under visual meteorological conditions (VMC); or

(b) the place of intended landing is designated as an isolated aerodrome and:

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

(2) available current meteorological information indicates that both 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:

(i) a cloud base of at least 300 m (1 000 ft) above the minimum associated with the instrument approach procedure;

(ii) visibility of at least 5,5 km or of 4 km more than the minimum associated with the procedure.
