I have a colleague who believes that the number in brackets after DA on a Jeppesen approach plate is the ACTUAL rad alt reading at DA/MDA. I say it is the height above the runway reference (i.e. QFE equivalent).
Approach 8-17 explains it rather nicely.
That number has nothing to do with RADALTs....your friend is dead wrong.
