C-Change. I doubt anyone in the industry doubts that it CAN be done, I take issue with the "one who knows all" that this is a simple thing- a mere change of procedure and the flick of an alarm switch. One never understands what his agenda really is.....I mean, he campaigns against ADS-B, the thing which would enable many of his wants, he rabbits on incessantly about putting resources to risks, yet seems happy to throw lots of resources at whatever risk he thinks fit (this very issue for example), closes FS, yet loves all the FS-type things they have in the US, campaigns like a bull in a china shop over things he claims strangle the life out of GA (holding at air force boundaries), yet remains silent on the real costs in GA (charging regime, corporatisation of infrastructure assets, fuel tax etc). He is an enigma.
