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

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/energy control unit.
