Call me a 'Dick-ophant' or whatever childish name you want, but I don't want a subsidy to fit what may turn out to be an expensive orphan system.
I want VHS, not Beta, please.
JM / SDD: Which ADSB system is the VHS, and which is the Beta, and how do you know?
Edited to add:
First, there is at present a semi-contractual arrangement that gets the subsidy for GA. A contract is based on offer, acceptance, consideration.
Should there be an attempt to pull the subsidy, there is a distinct argument that the contract is frustrated.
Unadulterated twaddle!
