Flying in ther winter can be warm and comfy. Everyone has their own ideas about this. I have tried to simply bundle up and use those heated pads. This helps but does not cut it for a professional trike operation in the winter. I need to stay warm all day and keep my customers warm all day. The only solution I have found the only thing that works for me is heated clothing. Simple.
Here is an excert that I have on my web site for winter flying:
It may seem that it is cold flying in an open cockpit when it is freezing out there. It may appear that winter is not the time to go triking, microlighting, ultralighting powered hang gliding. Let me dispel these misconceptions.
Yes it is cold out there but you can use a modern state of the art heating system used my the military. It is simply heated clothing. I now use heated gloves, boots and vests. Gloves are 22 watts. Boots are 22 watts. Vests are 44 watts. That totals 88 watts of heating right near your skin to keep you warm and toasty. Imagine trying to hold an 88 watt light bulb, it would burn your hands. This 88 watts is efficiently put where you need it to stay warm.
We have the technology
and can use it. Have looked and tried other systems
and chose the Gerbing heated clothing mainly because of
the technology plus it is available at the local motorcycle shop
so it is easy to get, add or replace as necessary. Other brands
probably do a good job also. Gerbings developed Microwire™
in response to a Department of Defense contract for heated
clothing for Special Ops Forces. You will use this to stay warm
while you fly. Enough said. Here we show you how we suit up with
all the heating clothing to keep you warm.
Check out what you see while flying in the winter. Snow,
cold/crisp air - warm and tosty.
For those do it your selfers how to design your own system.
