DETAILED RECOMMENDATIONS 3.1 Landing Lights (See Table 1) 3.1.1 General Provisions 3.1.1.1 Landing lights are used primarily to provide ground reference
19、 information during final approach, touchdown, ground roll, and takeoff, and to illuminate any major obstructions in the airplanes approach glide path or on the runway at night. 3.1.1.2 It may also be used for signaling purposes in flight. The landing lights may be turned “on“ when: a. Operating wit
20、hin 10 miles of any airport, day or night b. Operating in conditions of reduced visibility, i.e., haze, dust, etc. c. Operating under special visual flight rules (VFR) conditions d. Operating where flocks of birds may be expected (coastal area, swamp lands, migratory areas, etc.) This requires that
21、all or some of the landing lights have the ability to be activated when the Landing gear and slats/flaps are retracted.

27、ht landings. As a design objective, 21.5 lux (2 ft-c) minimum at 122 m (400 ft) in front of the pilot at touchdown attitude and 5.4 lux (0.5 ft-c) minimum at 91 m (300 ft) in front of the pilot during ground roll should be provided. Lux (ft-c) levels are measured normal to the light beam. It should
28、be noted that normal approach attitudes vary between particular airplanes, depending upon speed, flap conditions, etc. In most cases, the landing attitude and taxiing attitude of the airplane are not the same; however, the landing lights should accommodate adequate light coverage for final approach,
29、 touchdown, and ground roll illumination. So, for some airplanes, it may be necessary to re-aim the landing lights, once the aircraft is on the ground. 3.1.1.6 Minimum recommended number of landing lights required for night flying are listed in Table 2.

Flight tests for certification should include an assessment to d
32、etermine adequate color discrimination for runway and taxiway signs as well as color contrasts between the pavement and surrounding environment for the proper orientation of the aircraft on runways and taxiways.3.1.1.8 Possible locations of lights are recommended as follows: a. Typical Locations of
33、Landing Lights: 1. Nose landing gear strut 2. Each side of fuselage (ahead of wing) 3. Wing/body strake (wing root) 4. Flap track fairing 5. Lower wing surface (retractable), fuselage lower surface or side (retractable), or wing leading edge 6. Nose SAE ARP693D Page 6 of 18 b. Typical Locations of R
34、unway Turnoff/Taxi Lights: 1. Nose wheel gear (steerable) 2. Nose landing gear strut 3. Wing/body strake (wing root) 4. Each side of fuselage (ahead of wing) 3.1.2 Aiming and Illuminated Areas It is recommended that adequate landing light aiming and illumination be provided to cover the following ai
35、rplane attitudes:a. Prior to touchdown, the pilot will start using the lights as he initiates the flare. The landing light shall be aimed somewhatahead of the pilots vision limit, and along the glide slope (see Figure 1). b. Before the point of touchdown is reached, the airplane is positioned in a n
36、ose up attitude and the centerline of the beam moves further down the runway relative to the pilots field of vision. At touchdown, it is desirable to provide illumination ofthe runway centerline and possible obstructions as far as 122 m (400 ft) away from the pilot (see Figure 2). c. After touchdown
37、, the nose wheel gradually drops to the ground and the airplane assumes a ground roll attitude. At this point, it is desirable to provide illumination of the runway centerline at least 91 m (300 ft) away from the pilot (see Figure 3). d. Crosswind conditions should be considered in design of landing
38、 light installations. 3.1.3 Installation and Lamp Beam Adjustment It is recommended that the landing light fixture contain provisions to allow the lamp to be adjusted properly to insure that the correct horizontal and vertical beam pattern orientation can be achieved (see Table 1) if applicable. 3.1
39、.4 Controls 3.1.4.1 Each landing light should be controlled by a separate switch reference Part 25.1383 (b) “Except when one switch is used for the lights of a multiple light installation at one location, there must be a separate switch for each light.” unless an Equivalent Safety Finding has been a
40、pproved for a single switch installation. The most common reason for separate switching is to prevent propeller flicker. 3.1.4.2 One switch may be used for the lights of a multiple light installation if these lights are all installed at one location.3.1.4.3 For retractable landing lights, it should
41、be possible to turn the light on or off without altering the position of the light fixture by providing a separate switch for controlling the motor drive circuit. This switch may allow aiming control at any position between the fully extended and the fully retracted positions. 3.1.4.4 There shall be
42、 a means to indicate to the pilots when the retractable landing lights are extended reference Part 25.1383 (c). 3.1.4.5 An automatic control switch should be provided to turn off the landing lights, when they are installed in the wheel well and when the landing gear is retracted. 3.1.4.6 An automati
43、c control switch may be provided to operate the externally mounted landing lights at dim mode when the landing gears is retracted due to their high electricity consumption and to reduce the possible heating of other components on the aircraft by the lamp. An indication shall be provided to the fligh
44、t crew that this function is activated.SAE ARP693D Page 7 of 18 3.1.4.7 Consideration should be given to provide redundant lighting control circuits and lamps to minimize the consequences of failures and improve dispatch reliability. 3.1.4.8 For rotary wing aircraft the controllable searchlight shou
45、ld be so installed that when the light is fully stowed, the plane of the lamp mounting ring will be horizontal when the aircraft is in normal, level flight. The searchlight should be of a type that can be extended not less than 120 degrees from its fully stowed position. 3.2 Runway Turnoff/Taxi Ligh
46、ts (see Table 3) 3.2.1 General Provisions 3.2.1.1 Taxi lights are used to provide illumination when the aircraft is maneuvered on the ground at night. Runway turnoff lights are used to augment the taxi lights on large multiengine jet aircraft when taxiing. The landing lights are normally switched of
47、f to conserve the lamps and to avoid blinding oncoming traffic. 3.2.1.2 Sufficient intensity and beam spread should be provided to aid the pilot in locating the following: a. Taxiways (or painted centerline) b. Runway turnoff locations c. Obstructions which might contact any parts of the aircraft Th
48、e taxiing and runway turnoff lights should provide a minimum illumination on each side of the centerline of the aircraft to 3 m (10 ft) outboard from each wingtip. 3.2.1.3 As a design objective, 21.5 lux (2 ft-c) minimum at 15.25 m (50 ft) in front and 24.5 m (80 ft) outboard of the pilot should be
49、provided for the runway turnoff light, and 54 lux (5 ft-c) minimum at 30.5 m (100 ft) in front of the pilot should be provided for the taxiing light (see Figure 4). Lux (ft-c) levels are measured normal to the light beam. There should not be a non-illuminated gap visible between the taxi and turnoff light lit areas. 3.2.1.4 On small airplanes taxi lights may not be installed. If insta
