I have a 1949 Cessna 170A. Looking to see if anyone has a way or recommendation for adding pitot heat to a certified 170A. Looking to make a nice little soft IFR bird. Also any additional recommendations for IFR equipment I’m definitely curious. Thanks in advance.

When you join the Association, you’ll have access to the Document Library which has some info on this.

Re: Pitot heat for 170A?
Very common to add the later common Cessna L shaped heated pitot. Our TIC170A members library has 337s. I don't know but wouldn't doubt Cessna may have a SB to add it to the early 172. You should probably have a 35 amp generator minimum to make it practical to use, maybe even to get past the electrical load requirement on installation.
A heated pitot is not a requirement for IFR BTW.

Re: Pitot heat for 170A?
Thank you! I appreciate the info. I went ahead and joined. I currently have a Jasco alternator in it that i think will do the trick but I’ll double check. I’ve picked up ice a lot at well below the reported freezing level a fair amount in my local area so I would rather it for practical use.

The ORIGINAL (Cessna approved) heated pitot for the 170 was the Kollsman 518B-01 (aka “sharkfin”) such as is often found on C190s and C195s.
