17、ent.3. REQUIREMENTS:3.1 General:Markings shall be uniform and without distortion. All letters and numerals shall be vertically oriented and shall distinctly indicate the graduation to which each applies.3.1.1 Instruments and indicators:(a) Numerals on dials of instruments whose graduations are on th
18、e perimeter of the dial shall be within the inner perimeter of the graduations. Numerals on sub-dials and dials having arc-type scales with graduations not on the perimeter of the dial may be on the outer perimeter of the graduations, unless otherwise specified by the procuring activity.(b) Numeral
19、values on fixed circular scales shall increase in a clockwise direction. On a linear scale display, numeral values shall increase from left to right on horizontal scales, and from bottom to top on vertical scales.(c) On those displays which require positive and negative indications about a zero poin
20、t, positive values shall increase in a clockwise or upward direction and negative values shall increase in a counterclockwise or downward direction, unless otherwise approved by the procuring activity.(d) Instruments and indicators presenting information to the viewer as to the current status of an
21、important control or equipment shall be clearly identified by bearing the nomenclature which indicates the function being measured rather than a specific instrument title, For example, the altimeter should be labeled “ALTITUDE” and the tachometer should be labeled “RPM”. All identification markings
22、placed on instruments and indicators shall be subject to the approval of the procuring activity.3.1.1.1 Letter and numeral design: Letters and numerals on instruments and indicators shall conform to MS33558.SAE AS18012- 4 -3.1.2 Control panels: One letter and numeral design shall be selected and use
23、d for each control panel. Where possible, this same design shall be used on all control panels in the aircrew station.3.1.2.1 Letter design: The recommended letter form is shown on figure 1. This font is available for paste-up layout work, in double the specified sizes, as Artype S-274. The letter d
24、esigns shown in MS33558 are acceptable for parts covered by this specification. The following commercial fonts having the size ratios specified herein for the classes and types of control panels covered by this specification may be used. Where there is limited panel space for the panel nomenclature,
25、 a News Gothic Condensed letter font may be used upon the approval of the procuring activity. Stroke width of engraved letters shall be the same as that of the acceptable type fonts of the same letter heights.(a) Fonts for engraving:(1) Gorton extended(2) Groton normal(3) Gorton condensed(b) Fonts f
26、or printing and other reproduction methods:(1) Airport semibold(2) Futura demibold(3) Vogue medium(4) Lining Gothic No. 66(5) Alternate Gothic No. 33.1.2.1.1 Letter spacing: There shall be approximately one stroke width space between letters within words, and one standard letter width (see 3.2.2) be
27、tween words in groups. Because letters vary in the amount of stroke occupying the left and right edge of the letter-block space, spacing that is actually unequal between the letter blocks can appear more uniform than equal spacing. The lettering within words, except for overall panel identification,
28、 shall be arranged to read horizontally from the viewers left to right. Legend or contraction shall normally be arranged to read horizontally, unless for clarity of indication or for reasons of space limitation, a vertical arrangement is necessary. Vertically arranged letters shall be of equal width
29、 to provide a pleasing effect.3.1.2.2 Numeral design: The recommended number series is shown on figure 2. This font is currently available for paste-up layout work, in double the specified sizes, as Artype S-274. Numeral designs shown in MS33558 are acceptable for parts covered by this specification
30、 The following commercial fonts having the size ratios specified herein for the classes and types of control panels covered by this specification may be used. Stroke width of engraved letters shall be the same as that of the acceptable type fonts of the same letter height.SAE AS18012- 5 -FIGURE 1.

32、roke width space between digits forming a single numerical indication.3.1.2.3 Punctuation and symbols: Punctuation marks shall not be used. Specialized symbols, such as arrows, plus or minus signs, and degree markings, shall be used only when essential to the meaning of the legend. When used, symbol
33、s shall not exceed the adjacent lettering in stroke width.3.1.2.4 Legends and contractions: Generally, ease of interpretation must be provided without an excessive number of control panel markings. Contractions shall be substituted for complete words when space limitations prohibit the use of the en
34、tire word. No fixed maximum can be placed on the number of letters in a legend for it to be spelled out. Contractions shall be subject to the approval of the procuring activity.3.1.2.5 Lines: Marginal lines around grouped control markings and underlinings shall not be used.3.1.2.6 Marking sizes: All
35、 letter and numeral measurements shall be made from the outside edges of the stroke lines for other than machine engraving on opaque surfaces. For all mechanical engraving on opaque surfaces, the dimension controlling the size of letters and numerals will be measured from centerline to centerline of
36、 the stroke. All letters and numerals shall be proportioned to provide a pleasing visual effect. When one letter or numeral is selected at the lower tolerances, the remaining letters or numerals of the control panel shall also be selected at the lower tolerance.3.1.2.7 Display-control relationship:
37、Controls associated with a display should be proximal to the display in an arrangement whereby the display unit will be visible during operation of the control. The control and display shall be linked in a manner specified in MIL-STD-203 and MIL-STD-250.3.1.2.7.1 Control knob identification: Identif
38、ication markings of control knobs shall be placed on the adjacent panel area, not on the knob itself, except as otherwise specified herein and inMIL-STD-411.SAE AS18012- 8 -3.1.2.8 Control panel identification: Words and letters used for identification of an entire panel or the portion of the panel
39、including several controls making up a functional group shall be larger than the other letter heights used. The panel-identifying legend shall be located at the top of the panel and shall be standard horizontal lettering. Markings irrelevant to the operator, such as stock numbers and aeronautical ty
40、pe designations, shall be avoided.3.1.3 Counter displays: The number of digits that can be displayed on the counter shall be obvious to the operator at all times, regardless of the momentary reading on the display.3.1.4 Toggle switches: Except where readability is compromised, the identification of
41、the switch shall be placed above the switch. Where readability is compromised, the identification shall be placed adjacent to and easily identifiable with the switch. Switch positions shall be marked in the direction of travel. For center positions, the markings shall be placed on the right of the s
42、witch for left-hand operation and on the left of the switch for right-hand operation. When the location of the equipment is indefinite, the marking of center positions shall be on the left of the switch.3.1.5 Linear swtiches: The markings associated with a linear switch shall be placed to remain vis
43、ible during hand operation of the switch.3.1.6 Thumb wheels: The identification of thumb wheel-type controls that are perpendicular to the control panel and have a part of the wheel extending above the panel shall be visible while the control is being operated.3.1.7 Pushbuttons (non-transilluminated
44、): The pushbutton shall be illuminated by means of a chamfer on the rear of the panel mounting hole through which the pushbutton protrudes.3.1.7.1 Pushbuttons (transilluminated): The top surface of transilluminated pushbuttons shall be marked with appropriate legends.3.1.8 Switch guards: Switch guar
45、ds in general do not require special markings because of their installation. Markings for the switch shall be outside the area covered by the switch guard.SAE AS18012- 9 -3.1.9 Immediate action controls: All switches, buttons, and small handles or levers shall have a striped panel background, wherea
46、s large handles or levers shall be striped on the handle or lever. The striped colors shall be alternate orange-yellow and black. The black stripes shall have a width between 1/16 and 1/4 inch, and the orange-yellow stripes shall be three times the width of the black stripe. The stripes shall be app
47、lied at a 45-degree angle from the vertical, rotated clockwise. The striping shall begin and end with an orange-yellow stripe. Background striping around a switch or button shall be not wider than 3/4 inch nor less than 1/8 inch. If one side of a switch or button has less than 1/8 inch space, no str
48、iping shall be applied to that side. Background striping around a small handle or lever shall be no wider than 1 inches nor less than 1/4 inch. For night presentation, the immediate action control striping shall appear as illuminated stripes with color identical to the orange-yellow background strip
49、ing, color #33538 (see para. 3.3.3). The illuminated stripes shall be limited to panel background striping unless otherwise specified by the procuring activity (see 6.1). The illuminates stripes shall be 1/8 inch in stroke width and shall be located in the center of the orange-yellow stripes. The color and brightness of the illuminated stripes shall be in accordance with MIL-P-7788.3.1.9.1 Nomenclature: Where nomenclature is included on the control handle or lever, or as a part of the background, the nomenclature shall be insignia white on a black background.
