flying into snow showers without deice
I'm presuming flying IFR in light snow in a Skylane RG with no deice
equipment other that the pitot heat is OK if the temp is low enough to preclude sticking, perhaps -10c or less. This comes up as I contemplate flying to Minneapolis early next week. Just is case there could be other opinions though... |

This comes up as I contemplate flying to Minneapolis early next week. Just is case there could be other opinions though... I trained for my instrument rating downwind of Lake Ontario, New York State, during the winter of '02-'03. Most of my 17 or so hours of actual instrument conditions logged during the training were in moderate to heavy lake effect snow in temperatures from -2 to -15 degrees C. Other than a very light, white film on the leading edges, the snow never stuck to the C172 in any mass to cause concern during these, or any subsequent flights. -- Peter ----== Posted via Newsfeeds.Com - Unlimited-Uncensored-Secure Usenet News==---- http://www.newsfeeds.com The #1 Newsgroup Service in the World! 120,000+ Newsgroups ----= East and West-Coast Server Farms - Total Privacy via Encryption =---- |

If you can see then you are ok. Even heavy wet snow isn't really a problem.
Sometimes clouds can be "embeded" in the snow and they may contain ice. Mike MU-2 "Doug Carter" wrote in message om...

From my real life experience: your wings are not the main problem - but the
prop. I had 2 flights in where I had to go through light snow for landing and always the prop. was "iced" (from the spinner to half of the blades appr. - thats why the prop heating sits exactly there, if you have it ;-) - when you get out of the airplane and see it you are scared. If you have to go missed - I have my doubts that you will be able to get all the power. Now add some little ice on the wings/frame, more time in light snow, maybe even divert - I am not going to do that again.

Any ice on your prop came from flying through cloud, not snow. Snow is
already frozen and doesn't stick. Mike MU-2 "Bernd Seitter" wrote in message ... From my real life experience: your wings are not the main problem - but the prop.

I do not remember the temperatures (but it was not too cold, maybe -5C
Celcius on the ground - the ice did not melt from the prop). The cloud layers were thin (maybe 2000ft) - both flights happened in southern Germany during winter time, both alreay after sunset (quite early here in winter time ;-) No - I am not sure if the ice came from the clouds. But then I would have seen more ice pickup in the clouds on the wings, and this was really just small amount, compared to the "ice block" on the prop. I have been to similar and more heavy icing conditions, but with an appropriate equip. aircraft. There you could see the ice pick up very clearly on the radar-dome under the wing (C210) while flying - on the leading edge of the wing it is difficult to see (IMHO). On the ground I could see parts of the wings iced while the prop. was clean as it could be. Bernd "Mike Rapoport" wrote : Any ice on your prop came from flying through cloud, not snow.

A snowflake that falls into warm air (above freezing air) doesn't instantly turn to water. Parts of it may be water while other parts are frozen. This can stick to the airframe, or, particularly on certain Cessnas, quickly clog the air intake. I never had trouble in the 182 below about 25F, but I quickly clogged the air intake in heavy snow at about 32-34F once. Matt |

If it is melting then the temp is above 0Cand the water content isn't
supercooled and it won't stick. It can certainly clog the intake though. Mike MU-2 "Matt Whiting" wrote in message ...
