Helicopters registered in the United Kingdom – public transport operating conditions and performance requirements

128.—(1) The Secretary of State may prescribe requirements for helicopters registered in the United Kingdom which are not Part-CAT helicopters in respect of their weight and related performance and flight in specified meteorological conditions or at night.

(2) Subject to paragraph (3), a helicopter registered in the United Kingdom must not fly for the purpose of public transport unless the helicopter complies with the applicable provisions of the requirements which have been prescribed for its weight and related performance and flight in specified meteorological conditions or at night.

(3) Paragraph (2) does not apply to a flight for the sole purpose of training persons to perform duties in a helicopter.

(4) The assessment of the ability of a helicopter to comply with paragraph (2) must be based on the information as to its performance approved by the State of design and contained in the flight manual for the helicopter.

(5) In the event of the approved information in the flight manual being insufficient for that purpose the assessment must be based on additional data acceptable to the CAA.

(6) Subject to paragraph (7), a helicopter registered in the United Kingdom when flying over water for the purpose of public transport must fly at such an altitude as would enable the helicopter—

(a) if it has one engine only, in the event of the failure of that engine; or

(b) if it has more than one engine, in the event of the failure of one of those engines and with the remaining engine or engines operating within the maximum continuous power conditions specified in the certificate of airworthiness or flight manual for the helicopter,

to reach a place at which it can safely land at a height sufficient to enable it to do so.

(7) Paragraph (6) does not apply to a helicopter flying as may be necessary for the purpose of taking off or landing.
