An Aviation Advance, Cleared For Takeoff
Some quotes from a CBS story -
I can't see any planes," said Capt. Karen Lee, a veteran 747 pilot and director of operations for the world's 9th largest airline. (That would be UPS.) Commercial jets like hers do have a little screen that warns of imminent collisions, but it's crude, and not designed for navigation.
Is she talking about TCAS ?
So who would not love ADS-B? Who could possibly object?
And the UPS trial wasn't ADS-B's only success. The FAA also tried it in Alaska, where a lot of area has no radar services, presenting a very challenging environment for pilots.
And what were the results?
"We've reduced the fatal aviation accident rate in those particular areas on the order of, like, 38 to 40 percent," Capezzuto said.
Was that a reduction in mid air colisions due to ADS-B ????
