Article 101 Aeroplane operating conditions and performance requirementsI1
United Kingdom
An aeroplane registered in the Territory must not fly for the purpose of commercial air transport unless it complies with such data as may be approved by the State of design and contained in the flight manual for the aeroplane and the specified requirements or instructions given by the Governor under article 74—
in respect of its weight and related performance;
for flight in specified meteorological conditions; and
for flight at night.
An aeroplane need not comply with paragraph (1) to the extent necessary for compliance with the terms of an approval granted to the operator under paragraph (3).
The Governor may grant to the operator of any aeroplane an approval as provided for in the specified requirements or authorising it to comply with alternative performance standards appropriate to the aeroplane and specified in the approval.
An aeroplane registered in the Territory when flying over water for the purpose of commercial air transport must fly, except as may be necessary for the purpose of take-off or landing, at such an altitude as would enable the aeroplane—
if it has one engine only, in the event of the failure of that engine; or
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 aeroplane;
to reach a place at which, from a height sufficient to enable it to do so, it can safely land unless it is flying under and in accordance with the terms of an approval granted by the Governor.
