Panels and instruments

A big problem appeared when I tried to build the instruments as realistic as possible. Where could a normal person get in Europe exact pictures and drawings of the F-16`s instruments? I had to search for a long time and right now I do not have all the informations I would like to have. Even though, using different help and information. I was able to build the instruments quite realistic.

I had following information sources:
Based on these informations I could get relative precise data about the instruments. As the different instruments are built to be interchangeable, the size of one instrument could provide the dimensions of another. Even though some compromises had to be made, as the FLCS and the Throttle of Thrustmaster take more space and therefor panels placed near the controls have less space.

The caution- and warninglights


The "Panels"

All instruments with switches/buttons - which I will call "panels" in future, are black-painted, and manufactured from1.5mm aluminum plate disks. The labels consist of white "Rubbel" letters, which are used for labels of circuit boards etc. The necessary switches, buttons and rotary knobs do not unfortunately always resemble the originals. The rotary knobs were painted uniformly in grey (specifically ACRYL resin spray " TS32 - HAZE GREY " of the company Tamiya, available in all good model construction specialist shops). Original switches and buttons have the company EHC.



Real "Ext Lighting" panel...

...and the imitation

So far I like my panels quite good, but they still have a problem: they have not back-lighting, which is a big handicap during night flights, as far as you don't want to use any spotlight or candles inside your cockpit ;-).

Therefore I have been designing new cheap but still realistic panels. So far I have experimented with different materials like glass, plastic and now I have finally a solution that comes close to the real thing. This design has the advantage, that the panels can be mounted on a metal basis. How are these special panels built?

A black painted metall plate serves as basis for the switches to be installed. This plate is strong enough to resist even extreme handling of the switches.

Onto the metal base a 5 mm acryl panel is screwed on. This is done from the bottom. The acryl panel has the according drillings to hold the switches or required elements. The panel is painted with black enamel. The labels are done by laser-burning and have a depth of about 1 mm. Another way is to engrave the labels with a computerised engraver. There are many places where this labeling can be done.
The lighting is achieved by several LED, which are installed at the backside with a depth of about 4 mm. Lighting can be done using different LED colors (yellow, green or just white). The advantage of using LEDs is that they are cheap, do not produce heat and require low ampere. Normally about 4 LEDs would be enough to light any panel. The panels I saw, had a white light green shaded illumination. The advantage of using LEDs instead of 5V light bulbs is obvious. LEDs are cheap, do not produce heat and require only low amperes. If you have about 50 panels, these are facts to be considered.

Connection is easily made using connectors at the lower side. One connector is used to power the LEDs and another is used for powering the switches.

The panels are mounted onto the metal base using M4x4 metal screws. The original panels use bayonet screws, but they are difficult to get. By the way the drilling for fitting the panels is 9,54 mm.

The "Displays"

ADI-Display The instruments with displays (e.g. ALTO -, HSI or AOA displays) - I will call in future "displays" - consists of 3mm acrylic glass, which - with appropriate marks taken off - were painted black (color spray "black silk matt" of the company SPRAY COLOR). The displays are mockups from 1mm pasteboard, which - with prints colored and cut out - were stuck one above the other in several layers, e.g. a layer background, a layer of small pointers, a layer of large pointers, etc. Genuine instruments were too expensive for me, and are likewise connected to the computer only at immense expense.


The caution- and warninglights

ADI-Display I have been asked many times, how I have installed the warning-lights on the glare-shield. Well in some electronic shops (here in Germany Conrad-Electronik for example) have square lights of about 18 x 18 mm and 24 x 18mm (for the master caution). Normaly they are sold with 4 covers, each a different color (yellow, green ,red and white). The light bulb that is included requires 24 VDC and can be replaced by a LED. The label is made wit a CAD program and printed on plastic foil. The powering of the warning lights is done by the 32 point output modul of the EPIC card. That simple.
