Frostie Posted February 16, 2007 Posted February 16, 2007 Have'nt mentioned angles just the fact that the eye's scope is not limited, just dependant on the object being viewed ,resolution and range are totally different values.

GGTharos Posted February 16, 2007 Posted February 16, 2007 Yes, but they are also totally related :D More range = Smaller Object Smaller Object = Harder to resolve (and eventually impossible to see) which is my point. Your eye will see anything that is *big enough* and *big enough* is defined in terms of angular resolution in two dimensions, that's what I'm saying.

golfsierra2 Posted February 16, 2007 Posted February 16, 2007 Another important factor is 'movement'. If the other aircraft is right head on, only lower, the visible movement on great distances is close to zero. If it is flying abeam, you will notice the movement much earlier. kind regards, Raven....

AndyHill Posted February 16, 2007 Posted February 16, 2007 And if it's big enough and bright enough it's possible to slightly exceed the 20 mile barrier: http://www.physlink.com/Education/AskExperts/ae551.cfm _________________________________________________________________ Lock on MUST have a dynamic campaign system with multiplayer capability.

OldFrankHog Posted February 16, 2007 Posted February 16, 2007 "Your eye will see anything that is *big enough*" Exactly. So the eye doesnt have a max range. Even if the object is 20 square miles or 1 square inch....if its 100 miles away its 100 miles away. Join us today!!!
GGTharos Posted February 16, 2007 Posted February 16, 2007 Yes it does have a max range - for an object of specific size. [sIGPIC][/sIGPIC] Reminder: SAM = Speed Bump :D I used to play flight sims like you, but then I took a slammer to the knee - Yoda
Weta43 Posted February 17, 2007 Posted February 17, 2007 Quote: Yes it does have a max range - for an object of specific size. Not an absolute max range… As an object of a normally visible size gets farther away - yes it gets smaller & once it gets below the angular resolution of the eye it will be a dot. It may not disappear though. If it is radiating enough energy to cause a receptor cell to fire more frequently than the background radiation is causing all the other cell around it to fire at - you'll see it. In other words - if it's bright enough/has enough contrast against the background - you'll see it no matter how small it is, if it hasn't then at a certain point it will disappear. You need enough signal to override the noise, either from many receptors firing weakly, or one or two going nuts. (there's also the fact that atmospheric distortion - changes in air density causing random lensing/blurring mean that the image of a plane never actually gets down to the size you would calculate at long distances - just like the image of a star in the sky is not as close to a single point as it would be on the moon.
