Last weekend I began the building of the new panel with MCP, EFIS and radios I bought from CPFlight.
The panel is composed of a box of 64x17 cm to be positioned below the left monitor. In the upper side of the box there will be the EFIS then the MCP. At the bottom, from left to righ, XPNDR, COM, ADF VOR.
At the present the scheleton of box is completed and the elictrical components are in place. There will be one button for turning ON/OFF the electronics and a two poles switch button for upgarding the firmaware without insering the 2 dip switches in the rear side of the MCP by hand. In this way the firmaware can be upgraded without moving the panel.
At the right upper side of the front panel there is less space then I initially supposed: only a 8x6 cm little panel. I will put there the master switch, the GA and the button to switch between auto and manual setting of the VOR for the capitain.
In the first step this panel will be empty but ready for the replacement with the panel with the buttons.
For the GA button I have found at conrad a little squared button that can be reasonably used. It has no led on board and so it can't be back lighted.
The master switch is the most complex button because it has more then one led, at least a red and a yellow one for caution and warning. Till now I have found no button like that on the market. Of course it is sold by specialised web sites but it is very expansive.
The button to switch between manual and automatic VOR tuning can be one of the button (with a green led) I have already used for the light panel.
I am currently investigating the way to build the master switch and korry buttons. I subscribed to mycockpit forum and ther I have found some interesting solution. I will create a new post later with some good solution.
