to prevent inadvertent operation of the manual controls; and
(d) when turned on at either the cockpit station or the cabin crew station — ensure that the interior emergency lighting remains on in the event of interruption of the aeroplane's normal electric power; and
(e) when armed at the cockpit station — ensure that the interior emergency lighting comes on in the event of interruption of the aeroplane's normal electric power; and
(f) provide the level of illumination required under this MOS for at least 10 minutes at the critical ambient conditions after an emergency landing.

37 Interior emergency lighting system — if cannot be switched off
       An interior emergency lighting system that is designed to be continuously on and cannot be switched off need not meet the requirements in paragraphs 36 (a) to (e), but must meet the requirement in paragraph 36 (f).
Note   Photoluminescent and radioluminescent light sources are examples of lighting systems that cannot be turned off.
Subdivision 2.6 Exterior emergency exit marking

38 Application — CASR 90.235 (1) (b)
       The standards set out in this Subdivision apply for paragraph 90.235 (1) (b) of CASR 1998.

39 Passenger-carrying aeroplanes
       The standards set out in this Subdivision are for a passenger-carrying large aeroplane.

40 Exterior emergency exit marking — requirements
       40.1 The following must be clearly marked on the outside of the aeroplane for each emergency exit that is capable of being opened from the outside in accordance with this Subdivision:
(a) the external means of opening the emergency exit; and
(b) on the side of the fuselage or on the exit itself — a 50 mm coloured band highlighting the exit.
       40.2 Each marking, including the coloured band, must have colour contrast that readily distinguishes it from the surrounding fuselage surface.
       40.3 For subsection 40.2, the contrast must be as follows:
(a) if the reflectance of the darker colour is 15% or less, the reflectance of the lighter colour must be at least 45%;
(b) if the reflectance of the darker colour is greater than 15%, there must be at least a 30% difference between the reflectance of the darker colour and the reflectance of the lighter colour.
       40.4 For an emergency exit that is not in the side of the fuselage, the external means of opening, including instructions if applicable, must be conspicuously marked:
(a) in red; or
(b) if the background colour is such that red would be inconspicuous — in bright chrome yellow.
       40.5 For an emergency exit that is not in the side of the fuselage, if the means of opening the exit is located on 1 side only of the fuselage, a conspicuous marking to that effect must be provided on the
