I will probably transfer this info to another page, and make this a navigation page for the various other projects that will make up the total avionics package.

| EFIS/One CPU Installation | |||||||||||||||||||||||||||||||||||||||||||||||
| I am having Dave install the radios and displays in the panel, but that still leaves a lot for me to do on this end. First, I need to build a mounting bracket for the EFIS computer, that will reside under the front deck behind the panel. I searched the WEB of other builders and found a method I liked. I am going to build a cradle of sorts, that will hinge on the firewall, and allow me to lower the unit to remove and install cables, and remove the unit itself if necessary. | |||||||||||||||||||||||||||||||||||||||||||||||
|
|||||||||||||||||||||||||||||||||||||||||||||||
| Here is the top part of the bracket. The hinge will mount on the firewall, and the piece shown here will mount to another plate that will hold the EFIS unit | |||||||||||||||||||||||||||||||||||||||||||||||
|
|||||||||||||||||||||||||||||||||||||||||||||||
| Here are some additional pieces that will be used to make the entire bracket. I have not drilled the angle iron and side braces yet. | |||||||||||||||||||||||||||||||||||||||||||||||
|
|||||||||||||||||||||||||||||||||||||||||||||||
| Here is a closeup of the angle iron and brace. Now I have drilled them and they are clecoed in place. | |||||||||||||||||||||||||||||||||||||||||||||||
|
|||||||||||||||||||||||||||||||||||||||||||||||
| The complete assembly clecoed together without the bottom piece for the EFIS. | |||||||||||||||||||||||||||||||||||||||||||||||
|
|||||||||||||||||||||||||||||||||||||||||||||||
| Now the bottom of the EFIS CPU is set on the angle brackets to show how it will mount. The computer will set in this bracket and be secures with 4 screws. The hinge at the top will fasten to the firewall, allowing clearence for the computer box underneath the ribs. | |||||||||||||||||||||||||||||||||||||||||||||||
|
|||||||||||||||||||||||||||||||||||||||||||||||
| Jumping ahead. Here is the tray completed with the lower panel for the EFIS computer installed. The tray is hinged at the rear to attach to the firewall. The front flap is hinged so it can be out of the way when the box is removed, then rotated up to attach to the sub panel to hold the tray level. | |||||||||||||||||||||||||||||||||||||||||||||||
|
|||||||||||||||||||||||||||||||||||||||||||||||
| The rear of the tray (or FWD side it you want to look at it that way) is hinged to the firewall. I put a stiffener above the hinge to help handle the weight of the EFIS computer. | |||||||||||||||||||||||||||||||||||||||||||||||
|
|||||||||||||||||||||||||||||||||||||||||||||||
|
|||||||||||||||||||||||||||||||||||||||||||||||
| Completed in the raised or installed position. | |||||||||||||||||||||||||||||||||||||||||||||||
| Completed front view in raised leveled position. | |||||||||||||||||||||||||||||||||||||||||||||||
|
|||||||||||||||||||||||||||||||||||||||||||||||
|
|||||||||||||||||||||||||||||||||||||||||||||||
| Lowered position so that box can be removed in needed. | |||||||||||||||||||||||||||||||||||||||||||||||
| Lowered position showing easy access for cable removal, etc. | |||||||||||||||||||||||||||||||||||||||||||||||
| Now I can take the unit apart, and take it up to my avionics guy to punch the panel and install the radios. I will probably transfer this info to another page, and make this a navigation page for the various other projects that will make up the total avionics package. |
