A heated pilot would probably have something to do with the mile-high club.

The heated pitot for the 170 was originally a Kollsman unit. The type certificate lists the pn that was originally approved. It looks like a C-190/195 unit (sort of like a re-fueling probe.)
The later, "L" type heated pitot is sometimes installed, as you have indicated, usually salvage units for cost reasons. Some sort of approval will have to be made to keep it legal, either a field approval or STC.
TIC170A has paperwork and 337's etc. available.

Here is a picture of the Kollsman unit on a 195. I've only seen it installed on 1 example of a 170. It's not very popular.

canav8---Doug,
If your question about the heated pitot was legtimate; A heated pitot tube is for deicing in weather requiring it so that pitot and static information to the instruments will, hopefully, be maintained.

My question is legitimate. If you look at 605 in the TCDS it says Heated Pilot not Pitot. I knew what they must have meant. I just happen to catch this as I am updating an Equipment list. Another interesting point is how many of the placards that need to be installed in the front view of the pilot. Of all the cockpit panel pictures I have seen on here, I have not seen that many placards that are supposed to be installed. Last page of the TCDS. Just an obscure observation. Doug

Not to appear as a smart-A...just carrying on a discussion:

There are not a lot of placards. Note 2 (a) is only one placard, normally found on the glove box.
Note 2 (b) is found in the baggae compartment.

There are several other placards required by the installation instructions of certain equipment, however. And there are several that are specified as a part of installed equipment. (Example: the flap handle on a B-model has a placard integral with the handle which lists the available settings and the admonition against slips with full flaps. Another is the fuel selector placard which describes useable fuel and use of Both tanks for T.O./Landing. Note: A common mistake is the installation of a similar, but inappropriate C-172 fuel selector placard which advises against use of Both above 5K... but that does not apply to a C-170.)

Cessna has distributed many placards that are recommended, or are a part of the installation instructions (such as the use of pitot heat below 40-F, use of strobes on ground or in fog, etc.), but those are often construed as not-required equipment, unless specified in an STC.

As for item 605, perhaps you don't have the latest Revision 54, which states "pitot". The Members page of these forums will allow a fresh download of A-799, Rev. 54.

Clearly a heated pilot refers to heated seats. That would be a nice option, and now that I see it's called for in the TCD's, I should have no problem getting that through the approval process, right? I should be able to just take the seats out of my suburban, heated seats and all, and bolt them right into the 170. I think the color will even match!

[blueldr]

Sorry Doug. I can only blame it on age. I mis-read your original entry and thought it said "pitot" instead of "pilot".

[Bruce Fenstermacher]

I just found the picture I have of the only 170 I've ever seen with a Kollsman heated pitot. I knew at sometime we'd be talking about this and took the picture specifically for this occasioin. Which explains why I couldn't find it at first.

Now it seems we're talking about heated pilot installations. Well lets see. Hold the TIC170A convention in a dry county and you'll have several heated pilots.

Hold the convention in Duluth next week and you're going to need to heat the pilots!

SEB9317r1 covers the pitot heat placard. In SEB86-5 Cessna says a "seat locked" and "fuel contamination" placard are mandatory. Before you all rush out to order your placards be aware that, since this bulls**tin is not part of an AD, the FAA does not require it to be complied with.

I bought one of those pitot tubes at a popular online auction site. It has a line for the static as well as the pressure side. Any opinions on whether to use it or stick with the static port on the side of the fuselage?

Anyone thinking about using the Kollsman pitot needs to know that there is non-standard calibration required on the airspeed indicator if the Kollsman pitot is used. It will indicate fairly accurate at low speeds but will read too high at cruise if the non-standard calibration is not done. This has caused problems for 195 owners and is why Aspen did not include the 195 on the AML for their new electronic EFIS

As luck would have it, I did have an old revision of the TCDS. All of you are correct. It has been changed to Pitot again. Thanks for making me look twice. I thru the old TCDS out. I have rev. 54. About placards though, it says on the last page that these must be installed. How can you get around not installing them. The seat lock placard is also required. What is the fuel one you are refering to? The both tanks for T/O and Landing next to the fuel selector? or is there another one that must be affixed to the panel in front of the pilot. Thanks, I have no placards whats so ever. Any help would most be appreciated. Doug

I believe the ONLY placard req'd by the TCDS (for landplanes) is as described in note 2 (a), which is on the glove box in original installations.

The other placards are merely informational, and usually installed on convenient locations such as the fuel selector. Example: Despite the dire warning.... the placard on the fuel gauge prohititing take-off below 1/4 tanks is not only not required, it is not a restriction.
