"I think you have a fundamental and dangerous misunderstanding...."

You're having a laugh, right? Taking the Mickey? Pulling my leg?

You can't possibly be standing on the 'PIC rule' to justify your position.

My comment was, is and will remain to be, in relation to TCAS as you erroneously claimed its use for traffic separation. TA's are to to be responded to as it can create a 'Lord of the Flies' effect. Like 1 driver swerving across 3 lanes of a packed LA freeway. Chaos. When you have multiple aircraft at minimum separation with hundreds of people on board each one, you don't want one idiot going rogue and creating more conflicts than he solves.

If it was a non-transponder equipped glider you wouldn't get a TA to begin with so the point is moot.
