Re: At what cold weather temp do you stop flying?

You guys are way more resilient than I am. 35 to 40 and Sunny are my temps. I only put one heat exchanger on my exhaust sytem when I built my RV6. Food for thought for you Tailwind? builders. If you are going to fly in Winter in the north you? will want more heat. Sun helps a lot with the RV canopy.

Keith,

Interesting that you should post your question today, as the Polar Vortex has just swept into Texas.? Jeri and I spend winters in TX to avoid this cold BS!? It is 24 degrees here in Fredericksburg TX this morning, so I figure most of the native Texans are frozen solid.? Jeri and I finally put our long sleeve shirts on.? Anyway, to the point of your question....

My answer is "it depends".? If I am just wanting to go out flying for fun, I usually use 20 degrees F as my cutoff.? It's not that the airplane really would care, but I just don't enjoy the cold and getting the airplane out and back in just lets heat out of the hangar.? So I just say the heck with it if it is below 20.? However, if I have a "mission" that needs accomplishing, I will just do what I have to do.? The Super Cub has a pretty good heater, at least for the front seat, and if I tape up enough of the cowl inlets I can keep the oil temp up to around 160 or so, so I will do what I need to do.? Haven't had the Tailwind long enough to know if the cabin heat is worth a darn or not, and if I play my cards right I will never have to find out!?

I remember that I had to take a friend to pick up an airplane one time when it was about -20F, but the Piper Pacer I had at the time had an excellent heater so away we went.? He wasn't so warm on the way home in his new-to-him Skybolt though.? But that kind of mission is pretty rare for me, so I doubt I would have much reason to fly if it is that cold outside.? 20 is plenty cold enough for me!

Hope everyone has a great 2025!!

Joe

Hello All,
I am curious as to how cold it gets before you stop flying.? ? I have a really good heater in my plane and I think I have flown it down to about zero F but unless I have a specific mission,? I normally don't fly when it gets below about10 degrees F.? What do you do?? ?This is not really a post about how to start your cold engine or about preheating as I am going to assume we all preheat when it gets cold.? ? It has been cold in Wisconsin the last week or so.? I flew last Thursday and it was about 18 degrees F and all was fine other than oil temps only got to about 160 degrees.? CHTs were around the 300 degree mark.? ?
?
I have contemplated using some blue "painters tape" to partially cover the cowl inlets (would remove after each flight)? but have resisted putting any tape on my cowl.? ?I used to use duct tape on my Tripacer and have flown it to -15 F with no problems.
?
Just curious.? ?Winter flying can be very enjoyable.? Let's all have a great 2025!!
Keith
