If you do not have access to the aircraft technical manuals such as SRM, MM, etc., Jane's All the World's Aircraft is an invaluable source for this type of information.
Thanks very much everyone for your help so far. I should probably clarify a little better what information is needed, and why it's needed.
We build airborne data acquisition systems which are used by civil aviation authorities (like FAA) to test and certify ground-based aircraft radio navigation aids. There are some photos of the equipment and additional information available at:
These days we are building larger systems that include a dedicated operator workstation. These bigger systems need to be built to exact dimensions in order to fit inside the cabin and attach to the available mounting points in the aircraft.
If anyone could provide some links or sources of information I would sure appreciate it.
Since you are going to need a DER to approve the installation of your equipment in US operated aircraft, you should pick one who has access to the aircraft you are targeting. I work for a DAR in Canada, and we do this sort of thing all the time, especially King Air's, Navajo's, etc., so we already have access to the info for all the aircraft you mentioned above.
It sounds like your workstation is going to get larger. Do you expect it to span the whole cabin? This would be extremely difficult to approve, as the workstation would block access to the rear exits of the aircraft, and prevent fire-fighting there, too.
Locating a DER near you would be ideal. I presume that you work with your customers, aircraft operators, to install your equipment. The operators of the aircraft should know of a few DER's that have done other certification work in the past. Looks like your systems have already been through that process - judging by your website.
I don't know many DER's at all, because that's a FAA designation, and I am in Canada, where we have DAR's (with similar powers).
If what you're really looking for is engineering input into the airworthiness (ease of obtaining an approval) of a new design, then our experience would show that a few visits to your facility could be enough for an experienced DER, and FEDEX would do the rest.
2) Poor mans source but works just as well. B/CA Buisness and Commercial Aviation Magazine. The May issue of every year has the Planning and Purchasing handbook. contain cabin heights and widths.
