Low-Cost DIY Hangar Projects: Aircraft Cabin Dehumidifier | Aviation

When we moved east from arid northern Arizona to the very humid state of Florida, controlling corrosion on our trusty Cardinal became a full-time job.

Like so many others, we hangar the bird and treat the airplane’s wings, fuselage, and tail feathers to an internal spray corrosion treatment regimen every couple of years. I make sure to fly the airplane no less than once a week, and each time, get the engine up to operating temperature and keep it there for at least 45 minutes.

However, I wondered how I might protect our precious radio stack from the ravages of moisture and salt. 

I have had issues before with humidity and other kinds of electronic gadgets. Over the years, I found that when we left our musical instrument amplifiers idle in a humid environment, the rheostats would corrode at their contact points, resulting in a loud crackling noise when the volume was turned up or down. Thankfully, a little contact cleaner sprayed into the works, and a vigorous rotation of the volume knob usually cleared up the situation. And come to think of it, I had the same experience with the intercom volume and squelch controls on our Cessna.  

Our instrument panel contains the full spectrum of avionics history, from that 30-year-old intercom system and three light marker beacons,  to a couple of venerable King KX 155 NavComs, and more recently a digital transponder, IFR GPS, and autopilot. I noticed that each time I opened the boxes containing these new digital toys, the first thing that fell out was a little pack of silica gel commonly referred to as a desiccant. When these valuable little devices are being shipped, the manufacturers take the time to protect them from excess moisture. At this point my trusty co-owner, co-pilot, and spouse, observed that they made this kind of humidity absorbing desiccant for closets, footlockers, and even entire rooms. A trip to the hardware store was in order!

Full disclosure, what follows is not backed up by any…
