[F1ANNEX III U.K.

SUBPART I PERFORMANCE CLASS C U.K.

OPS 1.580 En-Route — One Engine Inoperative U.K.

(a)

An operator shall ensure that the aeroplane will, in the meteorological conditions expected for the flight, in the event of any one engine becoming inoperative at any point on its route or on any planned diversion therefrom and with the other engine or engines operating within the maximum continuous power conditions specified, be capable of continuing the flight from the cruising altitude to an aerodrome where a landing can be made in accordance with OPS 1.595 or OPS 1.600 as appropriate, clearing obstacles within 9,3 km (5 nm) either side of the intended track by a vertical interval of at least:

(1)

1 000 ft when the rate of climb is zero or greater; or

(2)

2 000 ft when the rate of climb is less than zero.

(b)

The flight path shall have a positive slope at an altitude of 450 m ( 1 500 ft) above the aerodrome where the landing is assumed to be made after the failure of one engine.

(c)

For the purpose of this subparagraph the available rate of climb of the aeroplane shall be taken to be 150 ft per minute less than the gross rate of climb specified.

(d)

When showing compliance with this paragraph, an operator must increase the width margins of subparagraph (a) above to 18,5 km (10 nm) if the navigational accuracy does not meet the 95 % containment level.

(e)

Fuel jettisoning is permitted to an extent consistent with reaching the aerodrome with the required fuel reserves, if a safe procedure is used.]
