Climb performance

[dokerr]

My manual is 300 miles away from me and I need some fast and dirty information. Acft: 170A/C145. Performance: Airport elevation: 8000Ft.
GW:1850. OAT 62F. Climb performance: 0 to 250 fpm at 65mph indicated.
What should the climb performance be according to the climb charts?
Thanks, DO Kerr N1327D

Thanks for the help. dokerr

Well I'm 45 miles away from my manual. Not as far as you but it's still dificult to read.

Solution. As a TIC170A member I can download the manual from the web site and look for you.

It says all data is at gross weight of 2200lbs and a McCauley prop. The highest altitude is 7000ft which at 60F, no winds, TIAS of 79, would render 370 ftpm.

The climb chart says nearly the same for standard conditions at 7500ft and TIAS of 709 would render 370ftpm.

Hope this helps.

doker IS a TIC170A member in good standing....and the Owner's Manual is available at the Members page of this website and contains the performance data.... BUT.....
Your aircraft is also required to HAVE ON BOARD the Approved Flight Manual....which also contains the data mentioned. (The AFM is a one-page document and available from headquarters@cessna170.org for minimal copy/postage,...or you can pay Cessna $25 for the single page.)

Can we have that (the AFM) posted so people can just print it out?

As I remember it there are 3 basic AFMs. I started trying to collect clean copies of them to scan clean up and give to the webmaster for posting. In this process I actually came up with about 5 versions of the AFM. I had asked people to review their AFM and if it was clean to make me a copy and send it to me. I only received one from Eric.

At the time I got some private feed back that one couldn't just copy the AFM. That the AFM had to be designated to the specific airframe buy Cessna. Buy scanning it and allowing others to print it might be a copyright infringement. In addition to all of this there was a concern for the size of the file that would be created and have to be stored on-line and the limited usefulness to members with slow connections.

I don't know what the difference is whether you use a copy machine at headquarters to copy the document or a scanner as far as legality (both FAA and copyright) is concerned but the TIC170A is already doing that according to George.

I did clean up the '48 version I received from Eric to an acceptable usable level. I had to reproduce missing type as well as eradicate hand written notes. Looking at the finished product you can't tell what I did but it took several hours. The later AFMs I have are in worse shape than the '48 version which is one reason I put the project on hold.

Perhaps I should revisit my project. I'm now I have a '48 and at least 2 versions for the A model. I think I need a B model AFM. In any case I could use cleaner copies of any of the AFMs which would make the process MUCH easier.

So anybody have a good clean copy of their AFM that they can make a good quality copy and mail it to me pleas PM me for my address. If I get something usable I'll restart the project.

Original AFMs were designated to the airframe by N-number/serial number. Replacement AFMs were issued by Cessna frequently without any ID whatsoever (other than specific model, of course.)
There are at least 4 flight manuals and 11 supplements identified by the TCDS, if I count correctly.
It may be possible to obtain the basic AFMs without airframe-specific identification (and therefore generically applicable to some aircraft), and some of those may be available from headquarters.
I don't have one in front of me, but I don't recall a copyright problem and the FAA ( formerly CAA) only requires that it be a true copy of the genuine document.
I have some fairly clear copies, and will try to get them posted after I return to my home office. (but no promises until I determine what difficulties may exist with the webmaster on this issue.)

For what it's worth, I've uploaded a PDF copy of my 170's AFM here: http://members.iphouse.com/jkr/N4401B/AFM.pdf .
N4401B is a 1955 B-model, S/N 26745. You'll notice that this AFM is assigned to N4401B, but it's dated 1950 and 1951. It appears to be generic for a 170B with a C-145-2 engine.

Cool, thanks.

[Bruce Fenstermacher]

Thanks John

I can download it a and clean it up including eliminating your number.

Like I said I have a usable AFM for a '48. i have 2 different AFMs for an A model but they both need a lot of work and if anyone would have a good clean one i'd appreciate a copy. I know have Johns for a B model but it needs some work. Doug if you could still send me yours that would be great.

I had intended to ask people at the convention to see their AFMs and hopefully collect copies of the good ones but I totally forgot.

When I'm done I'll give them to the webmaster for the members only download section.

John can you tell me if the AFM at your site is scanned at 100% or did you reduce it?

Bruce,
The sheet I scanned is 6" x 9", and from the looks of it, I'd assume it's the original. When I print the PDF I uploaded, I get something slightly smaller than that. I've uploaded TIF files for it, so you can play with it as you like: http://members.iphouse.com/jkr/N4401B/AFM1.tif and AFM2.tif.

Best Regards,

John
