OK, why do they cover the prop?
This month's EAA calendar features an Aeronca Champ on skis. I don't fly
much in weather that is THAT cold, so.... What is with the foxy covers on the prop? -- Christopher J. Campbell World Famous Flight Instructor Port Orchard, WA If you go around beating the Bush, don't complain if you rile the animals. |

Especially if it's a wood prop, I imagine it's simply to protect the prop from the weather. Even a metal prop might have to be deiced if you don't cover it; the cover simply saves some time during preflight. Pete |

If you are just shutting down for a few hours, prop and engine covers will help keep the engine warm. George Patterson Love, n.: A form of temporary insanity afflicting the young.

My prop cover was insulated so it did more than just keep frost from forming on it. -- Dale L.

The prop is a huge heat sink that draws heat out of the engine. The covers are put on to help keep the engine warm during $100 hamburgers in the winter. This guy also had a small Honda generator running to supply his Tannis heater. OBTW they were coyote skins not fox. It is not unusual to see them used up nort in the winter eh.

It kept the prop from dissipating the heat applied to the engine by my pre-heater. That McCauley was an 82 inch heat-sink. -- Dale L.

I guess it makes sense though...the prop does have a lot of surface area, so heat flow is easy to have. On the bright side, with the engine pre-heater pumping heat through the prop, you didn't have to worry about frost. Pete |
