When you fly NPA as CDFA, you may use MDA/H as the DA/H with no height add-on.
- Savi, we have been flying 'CDFA' - as in 'continuous descent final approach' now for many years - probably 20 or more since the UK airlines at least dropped the d&d technique. I think it is important to differentiate what we have been doing for years - which DOES require an addition as per the AB note you posted - from the 'New' CDFA which does not, but must be approved by the operator and regulatory authorities. Those airlines using the traditional 'CDFA' we all know still need to apply an addition of some sort as per your
"
Part 1 - minimum is MDA(H) - CDFA or non CDFA
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).
Part 2 - minimum is DA(H) - only CDFA
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)"
and your note from JAA itself says "The matter of using the MDA/H as a DA/H is progressing in the ICAO OCP and OPSP.
Until there exists a final result of the work in ICAO, it must be left to the discretion of each Authority to make decisions on the matter." so I felt your initial words (as quoted at the top) could be misleading. As always, stick to what your company tells you to do.
