2000 Ovation Pitot Heat Question
Flying in light icing conditions near Rock Springs WY yesterday with OAT -1C I had pitot heat switched on. And the TKS in operation. Everything going fine, the protected areas were clear and ASI normal.
But after a few minutes I for some reason happened to touch the area under the panel lower edge just above my left leg. I felt a metal box or bracket that was quite warm, too warm to touch for more than a few seconds, so I guess it was at least 50-60C. I aimed some air from the left vent at the hot spot. A few minutes later and out of the clouds I turned off the pitot heat. The metal cooled off rapidly.
i took a picture of the area. It is an aluminum bracket with some electrical component bolted on the top, non-visible side. Anyone know what this is, or have a schematic for the pitot heat? Is it a thermal switch or current sensor? And should it be so hot in normal operations? The part is marked 802338-501 but that is just the metal bracket number.
