I'm not sure that these lhuge unwieldy organisations like Boeing & Airbus have a chief test pilot these days.
Certainly BAE Systems have a CTP - the current one's and ex RAF chap. I think the "other" captain of the A-380 is Airbus' CTP, so they should have no decision making problems there, CTP in one seat, CEO in the other...
The RAF have a CTP too, but I think he sees an aeroplane once an month...
