I know it is getting increasingly difficult to find novel ways of doing something different. I could be wrong but I am not aware that anyone has placed an OAT gauge here. With a flick of the switch, this Davtron unit displays either fahrenheit or celsius. My thoughts at the time were that the instrument panel was already finished and I did not want to shoehorn another gauge into it and ruin my original vision of "symmetry." I thought that noting the OAT at any given time is something only occasionally monitored. So how difficult is it to simply look over the right shoulder from time to time? I hid its remote probe deep inside the right side NACA vent.
Another feature of the fused 1/2 amp installation is that I wired it to turn on with the master switch. If I ever forget to turn the master off, the OAT gauge remains lit. In its obviously visible location, the illuminated gauge can be viewed in bright light and well away from the cockpit environment.
Placing the OAT probe deep inside the NACA vent turned out to be not such a great idea after all. Because of the probe's proximity to the firewall, it sensed engine heat and reported readings that were far too high. I recently relocated the probe well away from the engine compartment. This time I centered the probe on a rear fuselage inspection cover and gave it plenty of service loop. The OAT readings are now accurate.
