Engine out three times? This will be the last then, before you change the engine and HSS ? Does the Gnome still have the detuning weights on the support tube? That's not a clue, just a question because the CT58 doesn't.
The 3D Cam is the bit inside the FCU that basically controls everything the FCU does.(Other than the seat/speed select interface.) A piece of metal with various profiles and cambers machined onto it. If I had a piccie then I would post it. As 212man said previously, all done using a slide rule. No computers in those days. Engineers were real engineers then!
Now you have the facts about salaries as well. See why good old Wastelands failed to tempt many people? Doing things on the cheap, as usual!! But still ripping off the taxpayer!
