Subject: | how cold is too cold? |
I was thinking about flying to Grand canyon (kgcn) which is about 1.5 hrs
from here. But I note that the overnight temperatures are brutal. Down to
about 0 F these days. The FBO will let me drag the plane into a heated
hangar in the morning to warm up, but will temps that low overnight do any
damage? Cracked plexiglass comes to mind. Any one have experience with
this sort of weather? Perhaps I should just wait a month or 2.

Subject: | how cold is too cold? |
Hi Tom,
I think you have one seriously babied airplane!! J This may be the
first time I=99ve ever heard zero degrees described as
=9Cbrutal=9D. J
I=99d say go =93 the Grand Canyon is gorgeous all the time
=93 even with a dusting of snow. Get started early and you can be
back home the same day and not worry about the overnight.
Being from Montana and then Minnesota =93 my airplanes sat in the
hangar on many -30 F nights without damage. Sitting outside
isn=99t much different than inside when it comes to sub-zero temps
(assuming a typical hangar). My coldest flying temperature while in
these areas was -10 F. Here in New Mexico, my RV doesn=99t
normally see temps as cold as my former planes but the occasional
sub-zero temp does occur. I=99ve not actually measured the inside
hangar temp on nights like this but I=99d bet it isn=99t
much different than the outside temp.
As far as damage goes, I can imagine the plexi might revolt if there is
a =9Chighly-stressed=9D area just waiting to crack but I
don=99t think I=99ve ever heard of this happening. Not
suggesting that I=99ve heard every possible story though.
What=99s too cold? I doubt there is a sitting still limit (within
reason). For flight; I dunno, the aspect that strikes me as the worst
for the airplane is being unable to get oil/CHT=99s up to a
reasonable temp at cruise.
Slightly different topic - I am NOT a fan of cold starts. I know the
book says they are ok but every car and airplane I=99ve owned
complain and scream in pain every time I do it to them. I like to
preheat (anything below about 35 degrees) and FBO=99s like to rape
you for them (in my opinion) and/or heated hangar space.

No, Tom, the cold won't hurt. I stored my RV6A in an unheated hangar and
just preheated the engine before flying if it got to or below 35-F and
no other problems. My now RV-12 is in the same situation, no plexi
damage, and no engine harm if pre-heated a bit.

One thing I've seen is an EFIS that literally took some time to warm up. We h
ad to run for about 15 min on the ground with the heater running before the s
creen would display anything other than a white blob in the corner. OAT was a
bout 15F and it was cold-soaked. In retrospect I'd have left a heater in the
cabin.

Subject: | how cold is too cold? |
Along the same subject=3B at what point is it necessary to pre-heat the eng
ine/oil before start-up? I have an O-320 and the plane sits out side @ HMT.
Temps drop to high 30's to mid 40's. I'm running 15-50w oil=2C and have a
strong starter/Battery. What's the preferred point at which one should warm
things up before cranking? Thanks in advance.

Subject: | how cold is too cold? |
I've been using the Reiff oil sump heaters for 10 years (Vans and ACS both
carry them). These are easy to install and work well. Anything below 40
degrees I plug them in. In a couple of hours the oil is up at 80 or so at
engine start.
Just don't leave them plugged in other than just before you plan on flying.
The moisture driven off from the now warm oil will collect on the upper,
cold part of the engine - like the cam.
