In accordance with. one embodiment ofmy in.-

vention, the. panel containing. thefacsimile mapw for an airport control. desk includes a top: section of transparent materiaha middle-section contain--.

ing the runway layout and a bottom.section orback-up plate on which illuminating equipment: is mounted.

For a fuller understanding of the nature and objects of my invention, reference may be had to the following detailed description, taken in conjunction with the accompanying drawing, in which:

symbol 23, which indicates the compass points,

is also provided on the field plan 2|.

The usual airport instruments 24, such as a wind direction indicator, a wind velocity indicator, an altimeter, a thermometer and a clock may be mounted on the upright panel [6 as.

shown in Fig. 1. A desk lamp 25 may also be provided on the panel l6.

As explained hereinbefore, it is frequently nee- As. shown, the desk comprises a base 1 26 composed of a transparent material, such as plasticor glass, 2. bottom plate 21 composed of non-transparent material, preferably sheet steel,

28 may be composed of a'relatively thinmatetened together by screws or bolts 29 which-may also servelto hold the complete map panel in 1 position on the sloping section I51 fl f it is desired 1 to change the map, the two sections may be dis- .mantled'and a new miniature layout installed-.1 1 If photographic film, paper, or cloth is utilized"; a new sheet containing the revised layout may be provided; -I f the layout is painted on one of the V 1 surfaces; the paint may be removed; or anew f plate having the revised layout-painted thereon 3 maybe provided. Since both'pla'stic and steel 1 are relatively inexpensive, the provision of a new i plate-' composedof either'of these materials will nct nvmye m great expense.

1 The bottom'section or plate 21 functions as a i back-up plate for supporting the top plate 26 and 1 3 also as a mounting plate: for supportingxa plu-' rality' of lights3l 'which'indicate the operation Z and location of the various lights located onthe' f 1 runways on the airfield. As shown 'in Fig. 3, j the'plate flis provided with holes 32in which a r the lights 3'l 'ar mounted. Each light 3| isdisposed in'a receptacle 33 whichrnay be of the type 3 utilized on telephone switchboards and is remov- 1 ably attached to 'thebottom plate 21.

' V Thef'receptacle 33 is supported by meansofa cylindricalsleeve 34havi 'ng a pair of oppositely disposed cars 35, as shown in'Fig. 5. The ears as are provided with holes 36 for receiving mount:- 1 ing 'screws" 31 for attaching the sleeve 34 to the pIate ZT. A slot 38 is providedin one side of f the sleeve 5 34, thereby permitting the sleeve to 1 spring open slightly to receive the receptacle 33. In this manner the'receptacle 33 is retained in a thesleeve 34- by friction. In case it is neces- I sary tq replace the light bulb, the receptacle 33 i may be removed from the plate 21 without re 1 moving the screws 3'l'and the sleeve 34;

of the indicating lights, the plate 21 may be readily redrilled topermitthelights to be mounted in their new location.
