The information is displayed. For it to be of any use, it would require a rapid refresh rate.
Now think about the bandwidth needed for several 'GPS' transponders to do this.
Or just LOOK OUT OF THE WINDOW!
I originally started this thread to see what people thought about the idea of a piece of cheap equipment that would not require any communication FROM other traffic for an a/c to know of that traffic's existence.
I would aggree that the GPS is not the answer, I think I got a bit off my original track by suggesting something to be carried by all.
What I think is needed is some form of onboard primary radar like the military "target aquisition" stuff but at an acceptable price. Something simple that will detect a chunk of aluminium heading your way, with no input from the "target". Of course this will never happen as if it were possible "someone would have done it by now". Where have I heard that before?
However as for "looking out the window", I presume you believe that I need to be advised to do this?
Perhaps I should point out that, contrary to popular belief, not all student pilots are as thick as two short planks. Whenever I fly from my local flying school I do try to get a window seat, so far I have always been successful & always in the front.
I spend the entire flight looking at the view apart from the occasional glance at those clock things.
These last remarks are not directed at you or anyone personally, but I have read "look out the window" so many times that I feel I must answer
I DO!!! But I can't see through the roof or the floor. Please don't tell me what the yoke or stick is for.
Now, why don't airline pilots do that & make the whole thing a lot easier, put CAA, NATS etc out of business?? Or is it just the poor light GA non commercial VFR pilot who has to do it, while the big boys sit doing the crossword or playing chess?
