Dejavu, it ain't eye candy.
Potentially, we could have all planes have a standard 3d model - shared by every plane - and then use the icons as identifiers. Below the eye candy, there'd be the various flight models of course.
Bit melodramatic, sure

. But it does illustrate the point.
Having *realistic* measurement system in a flight sim doesn't appear to be eye candy to me. It's about pure numbers, not about something pretty to look at.
Having said that, I would be at a loss if I switched to the metric system. Am so used to the Imperial one that a climb rate of 750m/m would confuse me. Heh.
Having it in Imperial sticks out though. it's like a sore point that really detracts immersion. it's sort of like having one of those studmuffing*tt Barney Dolls right next to the gunsight.
Bit melodramatic again. Is nice to exaggerate

. No, it's extremely pleasing and overwhelmingly satisfying to exaggerate.
