"Being equipped with ADS-B enables NASA's Ikhana to provide much more detailed position, velocity, and altitude information about itself to air traffic controllers, airborne pilots of other ADS-B equipped aircraft flying in its vicinity, and to its pilots on the ground. Currently, only air traffic controllers can see all the aircraft in any given section of the sky."
Some of our members might like to know that Ikhana is the NASA version of the Predator, or so my addled brain tells me.
Interesting progress, but still doesn't address or solve the issue of collision-avoidance with other GA aircraft who are flying by visual separation rules.
Mike: that is the kicker. It would upset my whole day to have a Predator meet my Bonanza head-on anywhere other than on the ground. And even that would tend to irritate me.
