Emergency equipment includ

15、es inflatable slides and other escape devices, life rafts, remote or supplemental survival kits, fire extinguishers, life jackets, oxygen masks, and such other items as might be used or operated in emergency conditions.2.3.2 INSTRUCTION PLACARDAny durable visual signage that requires an action from

16、either the crew, maintenance personnel, cleaning personnel or passengers (for example: Fasten Seat Belt while seated, how to operate emergency equipment).2.3.3 INFORMATION PLACARDAny durable visual signage that provides information to either the crew, maintenance personnel, cleaning personnel or pas

17、sengers (for example: Life Vest under your seat).2.3.4 FAVORABLE VIEWING CONDITIONSConditions in which placard foreground elements (words, pictures, drawings, symbols, etc.) are presented clearly and in high contrast to the background, with sufficient illumination and viewing time for recognition an

18、d comprehension. Viewing conditions are degraded if any of these factors is compromised.2.3.5 LOCATION PLACARDSignage that identifies the place of equipment stowage.2.3.6 WARNING PLACARDSignage that alerts a person to the potential for or presence of a hazard, indicating the need for additional eval

19、uation of its nature, probability, and magnitude, as well as the potential need for additional information. SAE INTERNATIONAL ARP577E Page 3 of 62.3.7 PICTORIAL PRESENTATIONInformation presented either by photograph or illustration. May be realistic or abstract.2.3.8 ABSTRACT PICTORIAL PRESENTATIONA

20、n illustration, such as a symbol, that is comprehensible only with prior instruction.2.3.9 REALISTIC PICTORIAL PRESENTATIONA pictographic illustration that is comprehensible without prior instruction (e.g., most photographs and “life-like” illustrations), and usually considered culture- and language

21、-free.2.4 Mandating and Recommending CriteriaShall: Indicates a mandatory criterion.Should: Indicates a criterion for which an alternative, including non-compliance, may be applied if it is documented and justified.3. GENERAL GUIDANCE A realistic pictorial presentation should be used whenever possib

22、le to convey information on equipment location and operation. A written word or phrase shall be used if the pictorial presentation alone is inadequate to provide effective information transfer or if the word(s) increases general comprehension of the placard. Unnecessary words should be eliminated.An

23、 abstract pictorial presentation (e.g., the picture of a red circle and slash to indicate “prohibition”) may be used if it is widely understood by the intended users.Placard letters, characters, pictures, and symbols shall appear upright to the intended user.Design, comprehension testing, and implem

24、entation of placards should be conducted in accordance with ANSI Z535 (Reference 4) or ISO 9186, (Reference 6). A success criterion of 85% correct responses is considered successful comprehension. However, standardized placards identified in Reference 4 may be implemented without furthercomprehensio

25、n testing.4. WRITTEN INSTRUCTIONSDISCLAIMER: This section is for English language only. For placards in other languages the content of this chapter should be considered as much as possible.4.1 Text shall be rendered in mixed upper and lower case type. Only the first letter of the first word in a sen

26、tence should be capitalized, since sentences with all upper case letters take longer to read. A single word or short phrase may be rendered in upper case type to provide emphasis (Reference 4, Section 2).4.2 Instructions shall be arranged so as to be followed in the correct order. Separated words an

27、d phrases shall be delimited, using numbers, arrows, bullets, etc., to indicate procedural order.4.3 Short sentences with short, easily comprehensible words should be used.4.4 Abbreviations should be avoided, except where shown via testing to be effective.SAE INTERNATIONAL ARP577E Page 4 of 64.5 For

28、 clarity, fonts of a simple form like Arial, Calibri, Times New Roman, Helvetica Medium etc. shall be used. Sans serif type fonts may be used for short words. Serif type fonts should be limited to placards having a large amount of text.4.6 An outline format should be used whenever possible for text,

29、 because of its generally improved readability over a continuous format. Examples of each type of format follow:a. Continuous Format: This hatch may be opened by lifting the cover, grabbing the handle and pulling it toward you.b. Outline Format:To open hatchLift coverGrab handlePull it toward you4.7

30、 Letters or numerals shall be rendered as follows (Reference 4, Section 2):a. no flourishes shall be used;b. critical details shall be simple and prominent;c. character features such as openings and breaks shall be readily apparent;d. stroke width-to-height for black letters on white background shal

31、l be between 1:6 and 1:8;e. letter width-to-height shall be between 1:1 and 1:5;f. numeral width-to-height shall be 3:5;g. stroke width-to-height for white letters on a black background shall be between 1:7 and 1:10.5. PICTORIAL INSTRUCTIONS5.1 Instructions should display the intended information in

32、 a realistic, rather than an abstract, manner, except where an abstract representation (e.g., symbol) has been shown via testing to be comprehended by the range of intended users. Comprehension testing of candidate pictorials and symbols should be conducted in accordance with Reference 4, section 3.

33、5.2 An instructional placard showing two or more operations shall indicate the procedural order. Numbers, arrows, letters, etc., should be used to indicate the order in which pictorial instructions are to be followed.5.3 Distortion of pictorial displays may be used to increase comprehension of the m

34、essage. For example, the color or size of an important element, such as a door handle, may be emphasized to draw a persons attention. Suchdistortion shall not degrade comprehension of the message.6. MINIMUM PICTURE AND WORD SIZEThe minimum letter height and size of, or distance between, elements of

35、a picture shall subtend at least 20 minutes of arc in favorable viewing conditions, at least 40 minutes of arc in moderate viewing conditions, and at least 50 minutes of arc in poor viewing conditions (Table 1; see Reference 4, Section 2 for more detailed information).SAE INTERNATIONAL ARP577E Page

For other viewing distances, letter heights (and distances be

37、tween elements) can be calculated for the various viewing conditions using Equation 1:(Eq. 1)7. PLACARD AND BACKGROUND COLOR COMBINATIONSForeground pictures, words, or symbols should be of a different color than the background. Some color combinations provide greater clarity than others, depending o

38、n shade, saturation, and intensity (see Table 2), as well as the color and brightness of illumination. Backgrounds with high reflectivity such as metallic silver should be avoided but if chosen it should be assured that the contrast between background and foreground color is equivalent to a non-high

39、-reflecting backround. Generally, foreground figures should be of a darker color than the background; however, a light-colored figure on a dark background (e.g., white on black) may be used where ambient background conditions favor such use or where standardized signage outside the aircraft environm

40、ent has provided general prior knowledge of the message. (see Reference 4, Section 3).Illumination of a placard shall, at a minimum, comply with the specifications in Reference 1.Table 2 - Legibility by color combinationLegibility Rating Color CombinationGood Black on White (Best)Black on YellowWhit

PLACARD PLACEMENT8.1 Location Placard Placement8.1.1 A location placard shall be placed so as to draw

42、 attention to the equipment to which it refers. 8.1.2 A location placard situated away from its associated equipment shall indicate the direction to the equipment.8.1.3 A location placard shall be placed on any equipment enclosure provided and shall be readily visible from all normal directions of a

43、pproach.8.1.4 A location placard referring to two or more types of equipment housed together should clearly identify each equipment type. The format of the placard should use informational or organizational principles that aid in understanding that there are two or more types of equipment located th

44、ere (Reference 4, Section 4).8.1.5 An interior placard should be placed to be readily visible by adults ranging in height from the 5th percentile female to the 95th percentile male (Reference 2).8.1.6 An external placard should be placed to be readily visible from positions on the ground or on ramp

45、equipment, as appropriate, by adults ranging in height from the 5th percentile female to the 95th percentile male.8.2 Instruction Placard Placement8.2.1 An instruction placard shall be placed on, or as close as is practicable to, the equipment to which it refers.8.2.2 An instruction placard shall in

46、dicate the method of operation and specify the function of the control(s) for the equipment to which it refers. 8.3 Warning Placard Placement8.3.1 A warning placard shall be provided for a (potentially) hazardous condition related to the use or misuse of equipment, as well as applicable standards an

47、d regulations, particularly with regard to use by untrained personnel. The placard should be implemented in accordance with Reference 4, sections 2, 3, and 4.8.3.2 A warning placard shall be placed such that attention is drawn to a potential hazard identified with a piece of equipment or with some p

48、ossible behavior on the part of passengers or crew that could result in injury or damage (Reference 5). 9.
