+50ft, if there is no published PEC for the aircraft.

Geoff, I quite agree that the RadAlt is purely secondary reference: it is unlikely to be giving a useable value at DA, given the vast variations of height around (and outside the boundaries of) the airport. There are plenty of approaches in Australia where there is a significant fall in the land surrounding the approaches to the runways.
