Well...
I've done both the 'dive 'n drive' and the CDA.....most of my flying career was dive 'n drive. Both work fine. Of course, dive 'n drive was the only option on my own airplane....back when I owned one.
But, the past few years of my flying I did CDA. I prefer it, without question, to the dive 'n drive procedure.
Just my opinion....
But, the original topic...we did add 50 feet to the MDA and made it sort of a DH...i.e. we flew it like a precision approach. Works great.
rudderrudderrat....yes, you are quite correct. Thanks for adding that.
This is the beauty of the technology.
Personally, I loved hand-flying the approaches. (Not SOP.....but, I did it in VMC.) With the precision the Bus allows, you can really fly a nice approach using Selected Guidance and 'The Bird'. 411A....brings tears to the eyes of us old guys.
Fly safe,
