HC,
One error above (now corrected) made in haste after a long day, was that, in fact, in addition to the "Minimums" call based on bar-alt using the MIN bug, you get both the "One Hundred" and "Altitude" calls from the rad-alt. The latter is set using the 'RA' bug. These in effect are the AVAD functions and the MIN is an additional setting primarily used for IF approaches. MIN is normallly set to 0 for VFR, once assured. RA is normally used in the same convention as the DH bug for an AVAD, but company dependent. We will use RA set to DH-50, MDH-100 ala BHL, though flying to DA and MDA (non of that QFE nonsense!), and the MIN set to DA and MDA.
