My company does not add this 50' to an MDA. In some cases, and these are the cases where the weather is on the limit, during this 50' you will see the rwy and a G/A is not necessary. If not, there is still enough margin to safely execute the G/A. I had already tons of NPA's where this was the case.
So you're saying that you initiate a G/A AT MDA and knowingly go below MDA because there is "enough saftey margin"?
