For how long werbil ?
This debate is getting really stupid............
I can not quote you exact numbers, for exactly the reason
YOU CAN NOT argue my suggestion, but I dare say the ADSB, even if they have some "outages".... will be having a much higher "UP TIME" than any of the radar heads we have had in the past or future.
FB FFS build a bridge mate and get over it......... I am starting think you are the radar salesman who is starring down the barrel of a losing battle. Get your company to start working on an ADSB system to suppliment (not totally replace) the worlds radar needs!
gee there is a novel idea!
