Ok thanks for the info.
Onto the next Q, ADSB- you can see the flight id right? Can you see the flight ID if you are out of range of the ADSB ground transmitter, eg acft to acft? or is it acft to ground to acft?
Also, to what range does the TCAS display go? Say I advise traffic is 20 miles 12 o'clock, can you see this on you display. What if the Traffic will pass behind you, can you see this on your display or is it only in the 90 degree/ish arc ahead.
I am interested as it will hopefully give me a better idea on what is useful information to pass as traffic. There isn't much point advising traffic that will pass behind you if you can't see it anywhere.
As pilots, what would you want in traffic info?
I am asking as i had a discussion at work the other day when and what is appropriate and useful when we have 2 that are 5 miles apart. Of course we have a sep standard so tfc is for info only. This is not a scenario where there is a break down of Sep.
thx
