DB -
I don't know the CHC SOPs and I don't know how good their radar is (not a search radar I'm pretty sure though, that was what we had on the SK) but an IP over 10 Nm away from the intended LS is rather extreme.
We used to let down from MSA well within 5 Nm and the final trans down from 200' was at about 1.25nm.
There may well have been other factors such as radar contacts as I explained earlier that may have affected their letdown procedure.
IIRC the S-92 has the facility to mark a target on top at 1000' (or whatever the required height is) and then complete a fully automatic letdown to the hover.
As for continuing IMC below MSA, we had special dispensation to do so because of the accuracy of the radar and the crew composition (dedicated radar operator) - again I know not what the CG AOC permits.
