As far as DA/DH is concerned, take whatever the approach charts (Jeppesen) tell you to use. Have you ever noticed how minimums are depicted? Like DA (H) 372' (200') on a CAT I approach. The DA is bold printed and the DH is in parenthesis for a reason. That tells you to take DA. On a CAT II approach you will find an RA. Therefore, use the radar altimeter on that one. Well, thatīs what Iīve been told to do when in doubt.
Or is the confusion basically when to use the radar altimeter instead of the baro altimeter? As before, the approach charts tell you when to use the RA. If it doesnīt say RA, use the baro altimeter.
