I've responded to it, but like all CAA and quasi-authority surveys, it already knows the correct answers and therefore has to steer you in that direction.
My PAW is not portable, having been installed in under the relevant BMAA TIL, so most of the questions do not apply.
The frequent underlining of portable makes the point, not only that they want portable responses only, but they wish to discount the best possible PAW installations, and that the sort of people who fill out surveys are not clever like them.
