Avionics

10-09-02
My mission objective for this plane is clear weather VFR flying. Unfortunately, here in the LA area, the ocean and its related humidity have a plan of their own. Very frequently we have ceilings of 3,000 to 4,000 ft. with a solid cloud layer above that is no more than 3,000 ft. thick. This is our wonderful marine layer that keeps VFR planes trapped into local patterns or grounded altogether. If you can penetrate the marine layer, you are back into clear sky flying which is the norm in the surrounding deserts (no marine layer there).

Consequently, I have designed my panel for light IFR operation. The objective here is to be able to fly IFR to VFR on top, or vice versa to deal with the marine layer. I have no desire to fly a high roll rate sport plane through extended IFR conditions - that just doesn't sound fun (or safe).

I was able to acquire a King KLN-89B moving map, IFR approach certified GPS with annunciator panel for under $2K. This should be a nice addition to the nav capabilities of the SL-30 radio. Both these nav devices will share the MD200 CDI. After much deliberation and consultation with many experienced pilots here is the panel I have decided upon.

Here is the first attempt at actually fitting all this stuff on the panel. It's a little busy, but it all fits.

The panel has been cut for all accessories except switches and breakers. I have decided not to use the EXP bus because it does not have enough circuits for my application. I'm still trying to decide whether to use combo switch/breakers, discrete switches and breakers, or switches and poly fuses.

The radio trays have been installed in the panel. The sub-panel has been cut and reinforced to accept the back of the trays. Here the radios and the EIS have been slipped in for a check fit. Now all I have to do is fill the rest of the holes and hook the wires to something.

I have test fit nearly all the panel devices that I have. I'm still waiting on my gyros. I need to make a decision on the switch type and positioning. I think I'm going to cut off the bottom of the panel left of the radios and make a removable switch sub panel that is easily lowered to allow access to the back of the switches.

Here is a pic of the panel painted and in the plane.

So I changed my mind. I sold the Apollo radios and King GPS and put in a Garmin stack with a 430 GPS. Here is this weeks final panel.
