Depends which flavour of Hawk . . .
A couple of years ago I was working on some stuff for BAe Hawk and the newest variants are being fitted with TCAS which is ported to one of the MFDs.
I informally discussed with the design team the effect of a Hawk climbing at high VS rates whilst crossing or operating within controlled airspace and warned of the potential 'bomb burst' effect of that on 'normal' airways traffic.
THEY understood then the implications, I have no idea if the info was passed on. I was the only guy on site that had actually operated TCAS!
