Hi:
I have a 1049H Crew operating manual but it's lacking. I need the manual for the 1049G/H with the Wright 988TC18EA1,
988TC18EA3
or 988TC18EA6 engine. I'm learning alot about the Connie from the manual I have, but the it lacks critical engine operation limits and other technical data. Any help in pointing me to a web site would be appreciated. I've been to Mach One manuals and a couple of others but can't find a manual that covers a Connie with those power plants. I think it's the Crew Operations Supplemental that has the data but I may be wrong.
Thanks,
Dave

Thanks Bill. I'm sending the guy an email to see what he has.

Hey Bill --- do you know where the data for the 972TC18DA-3 came from ? It might be easier to find a manual for this one but a search for this model drew a blank.

Hi,
Someone kindly made a C-121G manual available to the Connie Team. That had R3350-93A engines which are equivalent to the civil EA3's except that they allow an extra 1" MAP margin, probably because they had a government maintenance budget! The cruise etc charts are based on these engines.
I don't know what you already have but the DA1, DA3, EA3 and EA6 were mechanically identical, in fact an aircraft was allowed different versions fitted provided all the engines were operated at the limits for the lowest spec engine. Possibly just progressive strengthening made slightly better MAP limits possible and thus a higher power range. So the DA3 had the same TO limit as the DA1 but a higher METO limit. Then the EA3 had higher TO and METO power than the DA3 and finally the EA6 had the same TO and METO as the EA3 but a slightly higher cruise limit.
So apart from the EA6, the cruise settings for all these various versions should be identical.
If the manual from Ron Handgraaf does indeed have TWA's L1049G charts then these will be DA3's. I believe TWA's 1049H's had EA6's so if you're lucky there might be charts for these as well but you best check all that with Ron first.

Hi Bill --- Sorry for the long delay. I'm going to use your info and info from the Wright internet site which provides the military equivalent. Ron didn't have any manuals for the H, so I'm going see what Mach One has because they have numerous manuals for military connies. Thanks for all the help and with luck, I'll see what they have.
Dave
UPDATE --- I was able to find a complete flight manual that covers an EC-121D, 121H, 121Q and 121T that use the 3350-93A. The documentation for the 1049G update (Long Range Cruise Settings DA-3/EA-3) matches that in the flight manual which I think is the best I'll find for the 1049H. Of course, it also has a wealth of other data that's useful as well.

Hi Bill --- Thanks for the link. This info along with the manual I have will complete all settings for the 1049G and the H that used the same power plant. Also, this image gives me something to go on for the EA6 which I don't think I'll ever find a complete flight manual for. As for the G, you hinted earlier about upgrading that model. Is that in the works ? I also have the complete Long Range Power Chart thats more progressive for the various weights than the one provided in the update manual found on this site. If you want a copy, let me know. (actually it's PDF and I can't copy the pages, so if you desire, I'll just email the entire manual). It matches the one in the manual for the listed weights. Dave UPDATE: For those interested in obtaining the 1049G flight manual you can find it here: www.sicuropublishing.com/servlet/the-Download-Aircraft-Manuals-cln-Airframes-Manufactures-A-to-L-cln-Lockheed/CategoriesBottom of page and the title is: Lockheed EC-121 D H Q T Aircraft Flight Manual - 1968 The cruise portion starts on page 699. The manual is 1097 pages and the cost is 14.95. Well worth the 15 bucks. Dave . |

Hi Dave,
Thanks for the link but I think I've already got what I need. Volker just condensed the full version for the L1049G/H update and I think it's enough for most folks.
Wright produced about 80 of the EA6 version, 15% of the total EA3/EA6 run (source AEHS), although it seems that only about a dozen H's (no G's) were originally delivered with EA6. These were to TWA(6),KLM(3),TCA(2)and Californian Eastern(2). However it seems the DA/EA series had a maximum life of 20,000 hours so a few airlines might have used the EA6 as later replacements. Mind you, I'm not sure I can see what the attraction was as the T/O power was unchanged from the EA3 and who needed the extra cruise power ..........?

Hi Bill --- Thought you probably had the charts but was offering just in case. I was going to scan and post all four pages of the Long Range charts for anyone who might want to use them, but the chart in the manual has the auto rich sections greyed out over the figures so it's kind of hard to read. My scan made it worse. I'm still going to try to clean it up with a paint program and see if I can make it legible. I hope it's not a problem posting them on here. I do have one question about the EC121's. Same engine, same plane, different settings for same weight and same altitude for the newer models like the EC-121T. Not a piece of critical info, just curious as to why. And where in the world did you get all your knowledge about Connies --- very impressive.

I want to think Bill who provided all the information that made finding the 1049G flight manual possible. Also for providing all the info about the EA6. Thanks Bill, your help is greatly appreciated.
Happy Holidays to all:
Dave
