19、64. RECOMMENDATIONS 4.1 Design Criteria 4.1.1 Warning, Caution and Advisory System Indicators should be of the legend type i.e. containing alphanumeric characters or symbols. For military aircraft, actuation of the indicator should display the warning legend. 4.1.2 For commercial aircraft, Advisory

20、System Indicators may be either the legend type or bulls-eye type, with the legend type preferred. In the event a legend type indicator is not employed, an illuminated legend should be provided adjacent to the indicator. The bulls-eye indicator, if used, should not have the movable shield or shutter

21、 for dimming, but should be tied into the regular dimming system. 4.1.3 Indicators may be either Light Indicators or Mechanical Indicators. A lighted type indicator is defined as one employing lamps as the primary method of indication. A mechanical type indicator is defined as one employing motion a

22、s the primary method of indication, such as rotating a drum or electrically opening or closing a shutter. 4.2 Legend Color 4.2.1 Warning Indicator Lights should be Aviation Red in accordance with AS25050, except where NVIS compatibility is required. Where NVIS compatibility is required, the color an

23、d NVIS Radiance of the warning indicators should be in accordance with MIL-STD-3009. The legends should be opaque on a translucent background. 4.2.2 Caution Lighted Indicators should be Aviation Yellow in accordance with AS25050, except where NVIS compatibility is required. Where NVIS compatibility

24、is required, the color and NVIS Radiance of the caution indicators should be in accordance with MIL-STD-3009. The legends should be translucent on an opaque background.4.2.3 Caution Mechanical Indicators should be Aviation Yellow in accordance with AS25050, except where NVIS compatibility is require

25、d. Where NVIS compatibility is required, the color and NVIS Radiance of the caution indicators should be in accordance with MIL-STD-3009. The legends should be opaque on a translucent background.4.2.4 For military aircraft, Advisory Lighted Indicators should be Aviation Green in accordance with AS25

26、050, except where NVIS compatibility is required. Where NVIS compatibility is required, the color and NVIS Radiance of the advisory indicators should be in accordance with MIL-STD-3009. The legends should be translucent on an opaque background. 4.2.5 For military aircraft, Advisory Mechanical Indica

27、tors should be Aviation Green in accordance with AS25050, except where NVIS compatibility is required. Where NVIS compatibility is required, the color and NVIS Radiance of the advisory indicators should be in accordance with MIL-STD-3009. The legends should be opaque on a translucent background. NOT

28、E: FAR 25.1322 however, if abbreviations are used, select them so that the information can not be misread. The use of abbreviated legends not listed in the applicable documents should be approved by the procuring activity. 5.2.2 For military aircraft, the character height on the legend plate should

29、subtend a viewing angle of not less than 20 minutes of arc when measured from the aft most point of the design eye line at a viewing distance of 28 inches. Commercial type condensed letter fonts are identified in the applicable documents, allowing a maximum number of letters in a given space and sti

30、ll having sufficient stroke width to give a good readable presentation. 5.2.3 For commercial aircraft, figures, letters and numbers should subtend not less than the following vertical angles from the design eye position of the pilot (or crewperson) who normally utilizes the displayed information: Pr

31、imary (dynamic) nomenclature should subtend no less than 20 minutes of arc (6 milliradians). Alerting (dynamic) nomenclature should subtend no less than 15 minutes of arc (4.4 milliradians). Fixed essential nomenclature should subtend no less than 12 minutes of arc (3.5 milliradians). Fixed continuo

32、usly available nomenclature - 10 minutes of arc (3 milliradians) 5.2.4 The legend lights should not appear activated because of direct sunlight impingement in the unlighted condition; however, it should be readily apparent that the light is energized under high ambient light. Contrast requirements v

33、ary, depending on whether or not readability in direct reflected specular sunlight is required. 5.2.5 The mechanical indicators should have a minimum contrast ratio of 12:1 between lettering and background area adjacent to the lettering. 5.2.6 All opaque surfaces on lighted indicators, either the le

34、ttering or the background, should be flat black in accordance with FED-STD-595, color # 37038 to obtain maximum contrast. 5.2.7 All incandescent indicators should be designed for easy lamp replacement and unless the cap is captive indexing should be provided to prevent inadvertent installation on th

35、e wrong base. 5.2.8 All incandescent indicators should be designed to use two lamps operating in parallel. LED indicators should contain the LEDs and the driver, dimming and protection circuitry required for their operation. The indication should be readable with one lamp or LED failed. However, it

36、should be readily apparent that one lamp has failed. 5.2.9 The lighting design of the indicators should be such that the ratio of the dimmest point on the indicator to the brightest point should not be more than 1 to 2.

INSTALLATION 6.1 The effect of the best designed indicating system can be destroyed by installation techniques that could defeat the purpose of the system. The pilot must be able to see and interpret the

38、information presented. 6.2 The Warning and/or Caution System Master Indicators should be installed so that the pilot can not miss seeing any indication. Preferably these indicators should be installed within the 30 degree cone of vision. 6.3 The individual indicators may be installed elsewhere in th

39、e cockpit, providing the pilot still may view them without undue effect. Every effort should be made to locate the individual warning indicators within the 30 degree cone of vision.6.4 The number of indicators in a system should be kept to a minimum consistent with airplane system complexity. Too ma

40、ny indicators can present a confused picture to the pilot and possibly create an unnecessary hazardous condition. No indications should be given to the pilot unless it is absolutely necessary for safe operation of the airplane.6.5 The complexity and space limitations of modern aircraft most often pr

41、eclude the use of a standard design for indicators. However, it is recommended that aircraft designers standardize presentations where possible to stimulate confidence among pilots. Standard design of indicating systems can be as important to safety of operation as the brightness of the indicators.
