SECTION 3 U.K. Take-off and landing conditions

Take-off and landing conditions U.K.

75.—(1) Before commencing take-off, the pilot in command—

(a) of a balloon must be satisfied that, according to the information available, the weather at the operating site or aerodrome would not prevent a safe take-off and departure;

(b) of all other aircraft must be satisfied that—

(i) according to the information available, the weather at the aerodrome or operating site and the condition of the runway or final approach and take-off area intended to be used would not prevent a safe take-off and departure; and

(ii) aerodrome operating minima notified, prescribed or otherwise designated by the relevant competent authority will be complied with.

(2) Before commencing an approach to land, the pilot in command must be satisfied that, according to the information available, the weather at the aerodrome or the operating site and the condition of the runway or final approach and take-off area intended to be used would not prevent a safe approach, landing or missed approach.

(3) If, according to the information available, an aircraft would as regards any flight be required to be flown in accordance with the Instrument Flight Rules at the aerodrome of intended landing, the pilot in command of the aircraft must select before take-off a destination alternate aerodrome unless no aerodrome suitable for that purpose is available.

Aerodrome operating minima U.K.

76.—(1) The pilot in command must use the departure and approach procedures notified, prescribed or otherwise designated by the relevant competent authority for the runway or final approach and take-off area to be used.

(2) The pilot in command may deviate from a departure route, arrival route or approach procedure—

(a) provided obstacle clearance criteria can be observed, full account is taken of the operating conditions and any air traffic control clearance is adhered to; or

(b) when being radar-vectored by an air traffic control unit.

Operating minima

(3) For flights under Instrument Flight Rules, the pilot in command must select and use aerodrome operating minima for each departure, destination and destination alternate aerodrome which—

(a) must not be lower than those notified, prescribed or otherwise designated by the relevant competent authority;

(b) when undertaking low visibility operations, have been approved by the CAA or the law of the country in which the aircraft is registered.

(4) The pilot in command may commence an instrument approach regardless of the reported runway visual range or visibility.

(5) If the reported runway visual range or visibility is less than the applicable minimum notified, prescribed or otherwise designated by the relevant competent authority, the pilot in command must not continue the approach—

(a) below 1,000 feet above the aerodrome; or

(b) into the final approach segment in the case where the decision height or the minimum descent height is more than 1,000 feet above the aerodrome.

(6) If, after passing 1,000 feet above the aerodrome, the reported runway visual range or visibility falls below the applicable minimum notified, prescribed or otherwise designated by the relevant competent authority, the pilot in command may continue the approach to the decision height or the minimum descent height.

(7) The pilot in command may continue the approach below the decision height or the minimum descent height and the landing may be completed provided that the visual reference adequate for the type of approach operation and for the intended runway is established at the decision height or the minimum descent height and is maintained.

(8) Where the runway visual range is not available, the pilot in command may derive the runway visual range values by converting the reported visibility.
