Hi JimL
The FAA document may be the most concise guidance and I have to say it sounds sensible, however it is not really applicable for passing a test with a UK examiner. As 135 driver rightly says, the guidance to examiners in the UK is found in 'Standards Document 28' which states:
21.2 The candidate need not be failed if a height error of >100 feet occurs two or three times, but should be failed if any of the following occur:
Height error >200ft;
Height error >100ft sustained (& uncorrected) for an unreasonable time (normally about 15 secs);
At DH/DA, if the candidate fails to initiate the go around within 50ft of the DH/DA; or
If the candidate fails to maintain the helicopter within +50ft of the MDH/MDA at the MAPt.
Note, the requirement to
initiate the go around is the CAA's bold, not mine. Doc 28 can be found
here.

Sorry JimL, I wasn't trying to teach you to suck eggs, the quote and link were for the benefit of Windy.
