The head-up display (HUD) was developed to facilitate the transition be-tween Instrument and visual flight. The use of a IUD is becoming increasinglyCommon. In spite of the existence of a Military Specification and a MilitaryStandard which are written to promote consistency and to minimize occurrence

of incompstible methods of presenting information, inconsistencies do exist.The follkwin'g tables were prepared in order to facilitate comparison betweenexisting head-up d:•.splay formats, so that In the selection of symbols for fu- i

ture heia-up displays inconsistencies will be minimized,

The tables included in this report contain data on displays found in theA-7E, F-5, F-14, F-IS, F-=IlA, CL-84, and Al-BA aircraft. Data from the Mil'•-tary Specification pertaining to head-up displays, MIL-D-.81641(AS), and the Vrelevant Military Standard, MIL-STD-8584 are included. The information in thetables was taken from the references listed. Where available, the NATOPS Man-ual (U.S. Navy) or Technical Orders (USAF) were considered the primary source.Information from secondary sources was included in the tables where it indi-cated additional functions or alternative ways of displaying the same ftnctions.

D E SCR I PT I ON OF THE TABLES

Descriptive parameters are listed at the left edge of the tsbles. Func-tions are listed across the top edge. Functions are presented alphabeticallyand are consecutively nmbered. Where there is more than one means of display-ing a fwiction for a given aircraft, additional columns are used. The functionname is the same, and the same number is used with the notation "(cont)" to in-dicate continuation of the description. Explanation of the parameters, as nec-essary, is given below. Blanks in the body of the tables indicate that theparameter is not relevant or the required iniformation was not available.

Function - In general, displays present standard aircraft or weapons in- iformation and the function names reflect this. There are two types of excep-tions. One is where a function is peculiar to an aircraft; e.g., wing sweep in

the F.-14,, The other exception concerns functions without qualifying adjectiveswhere there should be a qualifier. An example is the use of the term "ai-r-speed" without the accompanying "indicated," "true" or "calibrated." In suchcases, a separate heading without the qualifier was included in the tables.

Figure No. - Refers to the figure which shows the display elements as du-scribed in the ables. In order to limit the number of figures, references aresometiimes made to a figure shd ting a display similar to but not identical informat to the display described. For example, the number of scale graduationsor intervals may be different, but the relationships among scale marks, nu-,merals, pointers and labels are the same. It is possible to determine fromthe table entries and the figure how the display looks. Numerals in circleson the figures refer to the function nmaber in the tables. Arrows fr,•m •,•csoenci-Pled nv,,rals point to display elements which are used for the function

whose number is given. Sometimes a figure number i.% given In a table entryfor a function and the number of that ftmcti,ýn does not appear on the figure.This is either because the figure portrays only that function, the figure isself-explanatory or the relationship -.s v.or Y,.•ely •xplained in the notes forthat function. In sor cases, one of the eo•,• c•o.W,tions holds yet there isa numeral on the figure. This is due to n cnservative nature of the au-thors' approach.

Forn of Display - The components of a fuwctional display, as shown in the Icorresponding figure, were classified as sqalos (vertical, horizontal, or cir-cular), ladders, digits, letters, alphanum.irics, or symbology.

Display Label - Any letter(s) used to label the display are indicated. Tnthe corresponding figure, a single letter has been drawn to indicate the posi-.tion Gf a single letter label; two letters have been drawn to show the positionof a double letter label. In each case, the letter(s) in the actual label maydiffer from those used in the figure.

Range of Variable - The range of parameter values which may be displayedis given.

Range Displayed - The range of parameter values which is displayed at agiven time is indicated.

Direction of Increase - The direction of increasing parameter values isgiven in relationship to the appropriate scalar display. For a vertical scale,parameter values increase as one reads up the scale, down the scale, or both;for a horizontal scale, values increase as one reads to the left, to the right,or both. For a circular scale, values increase in a clockwise or a counter-clockwise direction.

Fixed Scale - "Yes" indicates the scale remains stationary; "no," thescale acts as a moving tape.

Scale Values Marked - "Yes" ti licates scale graduations are labeled withnumerals to indicate parameter vaT )s.

Scale Graduations - The change in parameter value for the smallest grad-uation on a scale is given.

Moving Reference - "Yes" indicates a reference mark clhanges its positionon the screen in some manner.

Modes - With certain exce:itions, modes are listed as named in referencesources (see mode list). In cases where the table entry does not correspondexactly to the mode list, the table entzcy wili encompass more than one modeand will contain 6-4e word Lommon to thes.e modes. The only further exceptionis the use of the word "attack" to include all modes in the A-71T' where a weaponis used.

Notes - When a functitn description has been obtained from a secondaxyreference source (reference 4 or reference 6) this is indicated by inclus!onof the source number in the "notes" section.
