seat occupant. Additionally, they’d be up high, nicely in the field of view, and easily referenced during flight. Similarly, I opted to position the engine-monitoring unit directly above the throttle and mixture. It seemed logical that they be placed adjacent to one another. There seemed to be plenty of space for this, and I gave it no second thought as I pasted its likeness onto my Photo- shopped panel. Finally, I positioned the attitude indicator and horizontal situation indicator (HSI) in the most prime panel real estate available—directly in my field of view, above the yoke. Though I didn’t need to retain the ana- log airspeed and turn/slip indicators, I did so. I liked the idea of airspeed and coordination being represented by relatively large shapes that phys- ically move and are thus a bit more noticeable in my peripheral vision. Several hours later, I had created an extraordinarily poor-quality representation of my dream panel. Though severely pixelated, out of alignment, and not scaled properly, it seemed the perfect arrangement. Like a kindergartener presenting their artistic creation to their par- ents, I proudly presented my dismally-Photoshopped creation to my friend Jessica Voruda at NewView Technologies, an avionics and main- tenance facility in nearby Oshkosh, Wisconsin. Ever the professional, Jessica took pity on my feeble understanding of avionics installs. Marking my mock-up with red Xs like a teacher cor- recting a student’s test, she patiently explained the limitations inher- ent in modifying old panels. And there are quite a few to contend with. As it turned out, two critical concepts had escaped me. First, many radios and avionics are quite deep, extending well into the panel to- ward the firewall. And second, some aircraft types require ample in- ternal volume within a panel to provide the inner workings sufficient freedom of movement. Jessica explained that most of the new avionics I was planning to install had to remain clear of the entire central portion of my instru- ment panel. She further explained that, inside my panel, I’ve got a large central column shaped like a T that connects the two smaller control yokes. Because of the slope of the upper cowl, there’s a minimal amount of space above this column.
Additionally, when the control yokes are pulled back, this T-column moves in unison. It is, therefore, critical that nothing impedes its range of motion. New radios and avionics, for example. As with most matters of aviation, it is entirely possible to throw money at the problem until it goes away. In my case, I could source and install a newer U-column with available conversions that would pro- vide sufficient internal clearance to clear a central radio stack. How- ever, this solution was expensive and time-consuming, and my budget was already stretched thin. So it was back to the drawing board. Armed with a quick education and better images to drag around in Photoshop, I worked on creating a layout that was compatible with my newly-learned technical con- straints. After several days and many revisions, I presented a modified plan to Jessica. After a few minor tweaks of her own, we settled on a final plan and prepared for the fun second phase—how to incorporate minor changes and introduce design elements to balance modern ca- pability with original, vintage design. This initial phase was an interesting and educational one, however. It underscored the importance of finding and selecting an avionics shop with people who possess the patience and talent to educate and work with you along the way. Working with an impersonal shop that cares more about its bottom line and schedule, you feel like a number, like you’re just along for the ride. But with shops and technicians that explain every step of the pro- cess and patiently walk you through it, the entire project becomes that much more enjoyable and educational. I’m thankful to have found such a shop and such a technician. Spending tens of thousands of dollars is stressful enough, after all, and thus far, my experience has been a lot more fun than I expected it to be. ]
