Hello,
When you fly NPA as CDFA, you may use MDA/H as the DA/H with no height add-on.
(EU-OPS Operator - the minima calculated in accordance with Appendix 1 (New))
AIRBUS - Flight Operations Briefing Notes
From Non-Precision to Precision-like Approaches
The nature of the minima’s, MDA(H) or DA(H):
The MDA(H) being a minimum descent altitude, no altitude loss below the MDA(H) is allowed during the approach and go-around; this implies to either:
− Level-off at the MDA(H) - step-down / dive-and-drive technique - until visual references are acquired:
− Initiate the go-around above the MDA(H) - constant descent-angle technique - if no visual references are acquired, in order not to “duck under” the MDA(H).
This is obviously not required when the applicable minima is a DA(H), which is a decision altitude; if no visual references are acquired when reaching the DA(H), a go-around must be initiated at DA(H)
