As a foreign operator fairly new to the USA can someone enlighten me as to whether the 50’ for a CDFA approach needs to be added to the TERPS minima for 22L of 440’ . We don’t add for RNP approaches to LNAV / VNAV minima but do add 50’ if flying to LNAV minima...neither of these appear on the associated US plates?
Short answer:
MDA/H add 50.
DA/H don't add.
Long answer:
If the minimum is a "decision" altitude you don't add the 50'. If the minimum is a "descend" altitude, but you fly using CDFA, you add the 50'. This is because while you decide to go missed on an ILS or CDFA you are still descending, while if you are level at the MDA you are not.
Don't have the plate, but hope this helps.
