As for your comment on the seats, the seat pan is adjustable to allow for different crews body lengths. Fully down the pan is very close to the cockpit floor. Fully up the gap between the top of the seat pan and the bottom of the head box can be quiet small. Having them at different heights is probably the most accurate, from my near 20 years working with seats the crews rarely raise them before they get out

 

Hi pal thanks for you interesting comment regarding the seats being adjustable, never thought of that. However for these NACES seats in the F-14D version I am on about every picture I have seen whether crew or not the seats are the same height with the bat ears/canopy breakers in the same place (good point of reference)

Perhaps the seat pan/base is adjustable but that wouldn’t affect the overall seat frame height?

 

The problem with the hobbyboss D seats (both 1/72 and 1/48) is that the seats on the whole are either too short or generally undersized. There is too much empty space between the top of the seat and the underside of the canopy. This is most noticeable with the RIO’s seat. 

 

Have a look at any built hobbyboss D tomcat (both scales) on the web and compare to real photos. The RIO would hardly be able to see left and right over the sills! 

 

See here on my build in question

Great to see you back at these Tony. The Hobbyboss F-14 was one of my first builds upon returning to the hobby a few years ago and I crewed mine up. I can't remember if I added shims under the seats or under the figures so that they didn't look like toddlers sitting at the 'big table'.

See what you mean in the photo. I would think either undersized seat or mounted too low, or both. Just a bit more info that might help. The ejection gun (The telescopic tubes you see sticking up following ejection), are bolted to brackets on or near the cockpit bulkhead in two places. the bottom bolt is fixed on the ejection gun and we get the bolt into that one first. The upper attachment bracket on the ejection gun, if its the first time the set of seats has been fitted to that airframe, is left loose. This allows for minor differences in the distance between the two brackets in the cockpit. The bolt would be fitted then the bracket on the gun would be tightened up. If the seat and guns had been out for access and were been returned to the same cockpit they should fit first time. We only take the gun out if its in the way, removal of the seat assembly is usually enough for access.

Once the gun is in, the rest of the seat, comprising the main beam, seat pan, parachute assembly (head box) and Personnel Survival Pack that forms the seat in the seat pan are fitted as one, from above, with the six slippers on the inside of the main beam assembly sliding down the rail on either side of the ejection gun until the top of the ejection gun meets the inside of the main beam assembly.

We used to fit seats in Tornado in five pieces, Ejection gun, Main Beam Assy, Seat pan, Head Box and PSP. It saved removing the canopy. Health and safety in the early 90's stopped that practice and we had to remove the canopy and remove the seat up the ejection gun as one piece. How the F-14 community did it I cant comment but been Martin Baker seats I cant imagine much difference.

In summary, the seat should always, if fitted correctly be in the same position, the headbox will always be in the same position in relation to the underside of the canopy/cockpit sills, give or take a few millimetres depending on the lower bracket in the cockpit. the only part of the seat that should vary is the Seat Pan. I don't know the length of Main Beam on an F-14's seat but if you can find that out you can see if the seat length is to scale.

Hope that waffle helps a bit more Tony and isn't to baffling!
