Hi G,
I have 20 years experience in medium helos and light aircraft but not in medium to fair size fixed wing, but I totally agree with you about what can be viewed forwards from a large-aircraft seat, not that much!
I know we started this process knowing there would be a lot of artistic licence in this, so trying to get reality AND a useable panel is just not going to work, not without a bit of compromise.
You have to remember that the He115 was a medium-sized long-range observation and torpedo bomber and not a long range heavy bomber, with that in mind, the pilot would have to have good all-round visibility and especially close to the water for torpedo dropping and seeing the target.
You can see the construction sets the cockpit canopy high up on the top of the fuselage, so that the pilot and rear gunner/radio op have a good observation platform, more as in a fighter than a bomber. In fact if you look at the Grumman Avenger TBM, the pilot sits poking up out of the cockpit, see pic, to aid the torpedoing concept, as with most torpedo dropping ac.
I've got some pics of different flying He115s, see below, they are not in the taking-off or landing stage, but level flight, and you quite clearly see the pilots are sitting quite high up in the cockpits.
I hate to see a great panel, and all your effort, go to waste, or get butchered about and so it would not look like the real thing, just to get it to work. Maybe the answer is to have a half-way house, i.e. move the panel not quite down to where I put it but much nearer, to make it more usable?
Cheers
