[F1 OPS 1.297 Planning minima for IFR flights U.K.

(a)

Planning minima for a take-off alternate aerodrome. An operator shall only select an aerodrome as a take-off alternate aerodrome when the appropriate weather reports or forecasts or any combination thereof indicate that, during a period commencing one hour before and ending one hour after the estimated time of arrival at the aerodrome, the weather conditions will be at or above the applicable landing minima specified in accordance with OPS 1.225. The ceiling must be taken into account when the only approaches available are non-precision and/or circling approaches. Any limitation related to one-engine-inoperative operations must be taken into account.

(b)

Planning minima for a destination aerodrome (except isolated destination aerodromes). An operator shall only select the destination aerodrome and when:

1.

the appropriate weather reports or forecasts, or any combination thereof, indicate that, during a period commencing one hour before and ending one hour after the estimated time of arrival at the aerodrome, the weather conditions will be at or above the applicable planning minima as follows:

(i)

RVR/visibility specified in accordance with OPS 1.225; and

(ii)

For a non-precision approach or a circling approach, the ceiling at or above MDH; or

2.

two destination alternate aerodromes are selected under OPS 1.295(d).

(c)

Planning minima for a:

destination alternate aerodrome, or

isolated aerodrome, or

3 % ERA aerodrome, or

en-route alternate aerodrome required at the planning stage

An operator shall only select an aerodrome for one of those purposes when the appropriate weather reports or forecasts, or any combination thereof, indicate that, during a period commencing one hour before and ending one hour after the estimated time of arrival at the aerodrome, the weather conditions will be at or above the planning minima in Table 1 below.

Table 1
Planning minima — Destination alternate aerodrome, isolated destination aerodrome, 3 % ERA and en-route alternate aerodrome
Note 1 RVR.
Note 2 The ceiling must be at or above the MDH.
Type of approach	Planning minima
Cat II and III	Cat I (Note 1)
Cat I	Non-precision (Notes 1 and 2)
Non-precision	Non-precision (Notes 1 and 2) plus 200 ft / 1 000  m
Circling	Circling

(d)

Planning minima for an ETOPS en-route alternate aerodrome. An operator shall only select an aerodrome as an ETOPS en-route alternate aerodrome when the appropriate weather reports or forecasts, or any combination thereof, indicate that, between the anticipated time of landing until one hour after the latest possible time of landing, conditions calculated by adding the additional limits of Table 2 will exist. An operator shall include in the Operations Manual the method for determining the operating minima at the planned ETOPS en-route alternate aerodrome.
