I was wondering if the cockpit section of the 727 was longer than that of a 737 to accommodate the flight engineers station. I am considering having an engineers station in my 737, although I know the 737 is not built with one.
Thanks for the help.

No. The nose section back to station 294.50 is identical on the 707, 727, and 737.
Agree with Michael. Its the interior configuration that is different. A couple of more inches for the FWD Galley in the 737. Take a gander over at project 727 for some good pictures. I didn't see to much on airliners.net. I wished I had that bulkhead in mine. I do plan on adding it later. Don't know If it will be for SO or for lounge chairs.
I am having trouble determining the length of the cockpit. All the measurements I have seen reference from the bulkhead back, but not sure where this bulkhead is. And measurements vary somewhat. Many people seem to stop building aft of the seats.
Thanks.
Reference to the bulkhead is where the cockpit door is. 1st link is to a builders pictures that show the 737 area. 2nd link is showing the 727 door pictures 5 & 6. Michael, correct me if I'm wrong. As far as a measurement I can't do.

A couple of very talented builders. Emillio Bettech and Joe Maldonado.
There is a post I made referencing the length of the cockpit to the cockpit door bulkhead calculated using the station references aft of the datum plane in inches converted to feet & inches.
I'll have to find it tomorrow and post it. I don't even know where to begin looking here for it.
I found the post, but I only calculated the length to the rear of the #3 window.
I'll have to recalculate for the cockpit bulkhead. I'll get it posted for you tomorrow.
Here is the copied post:
Here is a bit of information I dug out of a Boeing 727 reference guide I have.
Each station on the airframe is measured in inches aft of the datum point.
The the 727's case the datum point is 130" in front of the aircraft. This is how long the flight test probe extended out in front of the aircraft during testing. The tip of this probe is '0' inches.
The very tip of the radome is 130" back and is called station 130.
From the radom tip to the the very aft of the #3 window frame is station 259.5. If you subtract 130 from 259.5 you get 129.5" or 10'-9 1/2". This is how long this part of the cockpit section is. Each of the ribs has a station point aft of the datum plane. This only has to be subtracted from the nose datum point and converted to feet and inches to get a measurement.
This will even tell you the spacing of the ribs under the windows as each has a datum reference.
This information is near worthless without addition data from a plan view with the same station identifiers, and a front view as well, but it is interesting to me.
Incidentally, the entire cockpit section as an assembly as mated to the front half of the fuselage goes to station 348.2, just aft of the left side entry door, or 18'-2 13/64"
Many thanks
What I see in many 737 builds is the actual shell section ending at the bulkhead. The rest of the cockpit may be included to the door, but it might be square at this point.
I am becoming tempted by the 727. I like the floor plan and openess of the cockpit So far I have been working on the shell, so I haven't commited to anything. I love the concept of an engineers station and an open view from 4 comfortable seats. I can picture it with hideous 70's polyester covered seats.
BTW, I will have access to a 707 flight deck section sometime this spring. It belongs to the aviation tech program at the school where I work. The program doesn't start until September and at this time it is encased in snow and ice. They also have a DC-3 section parked right in front. I am going to go wild with photos and measurements, but unfortunately I am building now and just will rely on measurements from others.
Anyway, thanks for the help.
BTW, here is a pic as to how the things looks now. It looks quite rough. But I build rough, true up the measurements, then build it pretty. I have come a long way since my first desparate pleas for measurements.
And thanks again.
What puzzles me Orwell from that thumbnail pic, is how did you end up with a *blue* piano? Is it going to be incorporated in your build for those long over-water flights? :)

Your length of the cockpit from the tip of the radome to the interior of the cockpit bulkhead wall is 13.70833' (13-81/2")
From the front of the main instrument panel just forward of the corner of the #2L window to the aft cockpit bulhead is 8.16666' (8'-2") This measurement could be off by as much as -4" as I don't know if the MIP is mounted to the forward rib location. It's the closest rib I could estimate given the drawing and knowing where the MIP sits in relation to the #2 window.
These measurements were taken from stations 196.5 to 294.5.
