IR Implementing rule

## CS ADR-DSN.M.615 General

(a) Elevated approach lights:

(1) Elevated approach lights and their supporting structures should be frangible except that, in that portion of the approach lighting system beyond 300 m from the [threshold](https://avioverse.aero/glossary/easa/threshold):

(i) where the height of a supporting structure exceeds 12 m, the [frangibility](https://avioverse.aero/glossary/easa/frangibility) requirement should apply to the top 12 m only; and

(ii) where a supporting structure is surrounded by non-frangible objects, only that part of the structure that extends above the surrounding objects should be frangible.

(2) When an approach light fixture or supporting structure is not in itself sufficiently conspicuous, it should be suitably marked.

(b) Elevated lights:

Elevated [runway](https://avioverse.aero/glossary/easa/runway), [stopway](https://avioverse.aero/glossary/easa/stopway), and [taxiway](https://avioverse.aero/glossary/easa/taxiway) lights should be frangible. Their height should be sufficiently low to preserve clearance for propellers and for the engine pods of jet [aircraft](https://avioverse.aero/glossary/easa/aircraft).

(c) Surface lights:

(1) Light fixtures inset in the surface of runways, stopways, taxiways, and aprons should be so designed and fitted as to withstand being run over by the wheels of an aircraft without damage either to the aircraft or to the lights themselves.

(2) The temperature produced by conduction or radiation at the interface between an installed inset light and an aircraft tire should not exceed 160°C during a 10-minute period of exposure.

(d) Light intensity and control:

(1) The intensity of runway lighting should be adequate for the minimum conditions of visibility and ambient light in which use of the runway is intended, and compatible with that of the nearest section of the approach lighting system when provided.

(2) Where a high-intensity lighting system is provided, a suitable intensity control should be incorporated to allow for adjustment of the light intensity to meet the prevailing conditions. Separate intensity controls or other suitable methods should be provided to ensure that the following systems when installed, can be operated at compatible intensities:

(i) approach lighting system;

(ii) runway edge lights;

(iii) runway threshold lights;

(iv) runway end lights;

(v) runway centre line lights;

(vi) runway [touchdown zone](https://avioverse.aero/glossary/easa/touchdown-zone) lights; and

(vii) taxiway centre line lights.

(3) On the perimeter of and within the ellipse defining the main beam in CS ADR-DSN.U.940, the maximum light intensity value should not be greater than three times the minimum light intensity value measured in accordance with CS ADR-DSN.U.940.

On the perimeter of and within the rectangle defining the main beam in CS ADR-DSN.U.940, the maximum light intensity value should not be greater than three times the minimum light intensity value measured in accordance with CS ADR-DSN.U.940.
