Paul,
I really like and use Eric=92s stuff!
I last talked to Eric about 6 years ago, he hasn=92t finished his pitot hea
ter. It was self regulating by use of the PTCs and he never finished as th
ere were some issues. The FAA test is to freeze water in the pitot at 40 b
elow and see if the heat clears it within some short time set by the Feds.
He and I talked about it, I felt it would be worth it for those light snow
and drizzle days, but I don=92t fly in that anymore so I dropped the idea
also.
All the 7-10 amp ones (Dynon/Gretz etc.) in Aircraft Spruce for experimenta
ls work OK. Just 7 amps! I=92ve installed three. They do have a PTC type
circuit to limit the amps to what is required so they are somewhat reasona
ble to install. I would recommend a second alternator though.
Regards,
Bud Yerly

Subject: Re: Europa-List: Heated pitot
I downloaded this document written by Eric M. Jones describing a low energy
heated pitot tube. It was on my "to do" list but I never got around to it
.

A year or so ago I remember reading someone's account of designing his own
heated pitot tube using only v. modest amounts of electricity. I thought I
had carefully filed the article but cannot find it. Does anyone have the de
tails or know what progress has been made?
