Tip: Panel Rib relocation for EFIS installation
 

There are some very good EFIS displays out there just waiting to be installed.

On the tip-up instrument panel the F-745 rib is in the center of the left side of the panel so this rib needs to be moved to allow the installation of the EFIS screen.

My solution was basically the same as Dan's only I cut down the existing rib and modified two F745 ribs to fit on either side of the EFIS tray. (Hey, why not, they are cheep enough.)

The reason I installed two extra ribs is to limit panel vibration, which can cause instruments to fail and make them down right hard to read.

Thanks for the tip. I'm in the same boat planning a D100 install on a tip-up. Adding an extra rib is a good idea.

hmmm
 

I did not add the extra rib and nothing vibrates or moves on my panel.
I don't see the extra rib as necessary, in fact it just gets in the way
of other things you may want to add later as it take up space.

If you are concerned about vibration cut your panel out of .090
stock instead of vans .063, the extra mass will dampen vibrations better,
but then you are adding weight to the plane.

I left the left rib out completely (ahead of the sub-panel). The panel itself is .090 with a sub-frame from Affordable Panels.

A guy with a Super -7 has this setup and he has no problems. That's what inspired me.

Moved mine
 

Thanks everyone
 

It will be awhile before I'm at this stage so we'll see what happens.

Meanwhile maybe MGL avionics will come up with a slick NAV/COM to go with the new slick COMM they just advertised!
