Aerial platform? Ah yes! I generally shoot with either a 28 or 35 mm lens and usually run at a 500th of a second. I can get away with 250th for most shots, but occassionally a get a 'dud' at this speed. Agree you certainly need to be using a shutter speed applicable to the situation.
On a slightly different tangent, an issue directly related to shutter speed is aperture. Obvious enough. In good conditions, an ISO of 100 and a shutter speed of 1/500th will give a correct exposure of lets say f8. In dull conditons, with the same ISO and shutter speed, the correct exposure may be say f 2.8. That may be the maximum aperture of the lens. Traditionally, lenses don't give their best (read 'sharpest') performance at maximum aperture (wide open), but more towards the centre of the f-stop range. In other words, between f4 and f8 for a lens that has a range of f2.8 and f22 say. So a better result in low-light conditions may come from using a higher ISO rating EVEN if the camera can expose correctly using the lower rating.
Case in point. For my 'conventional' aerial photography, I use a medium format camera. The results I get from it using an aperture of f2.8 are noticably poorer than when I am using f4 or smaller (bigger number)
That said, I am using an Olympus C8080 on my heli rig, and after doing some tests, find there is little difference in sharpness between max aperture and several stops smaller.
Conclusion: trial whatever gear you are using to determine whether it performs better at certain settings than others.
