[F1 SUBPART L SINGLE-ENGINED TURBINE AEROPLANE OPERATIONS AT NIGHT OR IN INSTRUMENT METEOROLOGICAL CONDITIONS (SET-IMC) U.K.

SPA.SET-IMC.100 SET-IMC operations U.K.

In commercial air transport (CAT) operations, single-engined turbine aeroplanes shall only be operated at night or in IMC if the operator has been granted a SET-IMC approval by the competent authority.

SPA.SET-IMC.105 SET-IMC operations approval U.K.

To obtain a SET-IMC approval by the competent authority, the operator shall provide evidence that all the following conditions have been complied with:

(a)

an acceptable level of turbine engine reliability is achieved in service by the world fleet for the particular airframe-engine combination;

(b)

[F2 specific maintenance instructions and procedures to ensure the intended levels of continued airworthiness and reliability of the aeroplane and its propulsion system have been established and included in the operator's aircraft maintenance programme in accordance with Regulation (EU) No 1321/2014, including all of the following:

(1)

an engine trend monitoring programme, except for aeroplanes first issued with an individual certificate of airworthiness after 31 December 2004 that have an automatic trend monitoring system;

(2)

a propulsion and associated systems' reliability programme;]

(c)

flight crew composition and a training/checking programme for the flight crew members involved in these operations have been established;

(d)

operating procedures have been established specifying all the following:

(1)

the equipment to be carried, including its operating limitations and appropriate entries in the MEL;

(2)

the flight planning;

(3)

the normal procedures;

(4)

the contingency procedures, including procedures following a propulsion system failure, as well as forced landing procedures in all weather conditions;

(5)

the monitoring and incident reporting.

(e)

a safety risk assessment has been performed, including the determination of an acceptable risk period if an operator intends to make use of it.

Textual Amendments

F2 Substituted by Commission Implementing Regulation (EU) 2019/1387 of 1 August 2019 amending Regulation (EU) No 965/2012 as regards requirements for aeroplane landing performance calculations and the standards for assessing the runway surface conditions, update on certain aircraft safety equipment and requirements and operations without holding an extended range operational approval.

SPA.SET-IMC.110 Equipment requirements for SET-IMC operations U.K.

Aeroplanes used for SET-IMC operations shall be equipped with all the following equipment:

(a)

two separate electrical generating systems, each one capable of supplying adequate power to all essential flight instruments, navigation systems and aeroplane systems required for continued flight to the destination or alternate aerodrome;

(b)

two attitude indicators, powered from independent sources;

(c)

for passenger operations, a shoulder harness or a safety belt with a diagonal shoulder strap for each passenger seat;

(d)

airborne weather-detecting equipment;

(e)

in a pressurised aeroplane, sufficient supplemental oxygen for all occupants to allow descent, following engine failure at the maximum certificated cruising altitude, at the best range gliding speed and in the best gliding configuration, assuming the maximum cabin leak rate, until sustained cabin altitudes below 13 000 ft are reached;

(f)

an area navigation system capable of being programmed with the positions of landing sites and providing lateral guidance to the flight crew to reach those sites;

(g)

a radio altimeter;

(h)

a landing light, capable of illuminating the touchdown point on the power-off glide path from 200 ft away;

(i)

an emergency electrical supply system of sufficient capacity and endurance capable of providing power, following the failure of all generated power, to additional loads necessary for all of the following:

(1)

the essential flight and area navigation instruments during descent from maximum operating altitude after engine failure;

(2)

the means to provide for one attempt to restart the engine;

(3)

if appropriate, the extension of landing gear and flaps;

(4)

the use of the radio altimeter throughout the landing approach;

(5)

the landing light;

(6)

one pitot heater;

(7)

if installed, the electrical means to give sufficient protection against impairment of the pilot's vision for landing;

(j)

an ignition system that activates automatically, or is capable of being operated manually, for take-off, landing, and during flight, in visible moisture;

(k)

a means of continuously monitoring the power train lubrication system to detect the presence of debris associated with the imminent failure of a drivetrain component, including a flight crew compartment caution indication;

(l)

an emergency engine power control device that permits continuing operation of the engine at a sufficient power range to safely complete the flight in the event of any reasonably probable failure of the fuel control unit.]

Textual Amendments

F1 Inserted by Commission Regulation (EU) 2017/363 of 1 March 2017 amending Regulation (EU) No 965/2012 as regards the specific approval of single-engined turbine aeroplane operations at night or in instrument meteorological conditions and the approval requirements for the dangerous goods training relating to commercial specialised operations, non-commercial operations of complex motor-powered aircraft and non-commercial specialised operations of complex motor-powered aircraft.
