Okay aerial guru's: question about film size, focal length, and the jitters

Lenses & Lens Accessories - www.largeformatphotography.info
This is somewhat hard to express accurately in my question. Let me give a barnyard example: lets say that i can easily hand-hold a 50mm lens in a Cessna effectively and get clear (non camera-motion blurred) aerial images on FF digital camera. If I use a 150mm lens on a 4x5 camera, under the same conditions, can I expect the same results?

In short, does a normal-ish angle-of-view lens "shake" any more on 4x5 compared to 35mm? By "shake" I mean "create blur caused by camera/lens movement."

Givens: Pretend that both cameras are perfect and I hold them exactly the same for this little experiment; the aircraft vibration, wind, altitude, everything other than the lens and the film/sensor size are the same. Also, I am not referring to the relative motion of the target below the aircraft due to the speed of the plane.

I use 50mm for 35mm, and 150mm for 4x5 as that is what I have in real life. I dont want to argue about 'what is normal.'

I understand re: gyros and I have one. Its just that I will shoot using 3 cameras and to have a gyro on 1 gets unwieldy in the cockpit. Therefore, I am simply exploring the relationship, if any, between focal length, angle of view, film/sensor size, and image blur due to motion caused by camera-lens movement (rather than the speed of the aircraft over the target).
