<you say level flight at the MDA is a big no no. I was just wondering what else can you do at MDA, after all the only thing you can do at MDA is fly level until you get visual or MAP. Even with a continuous descent profile you still need to level out at MDA if your still in IMC>
It's something practiced in the airlines I have worked for, but not in corporate.
NPA vertical profile is flown as per the chart, but with a corrected MDA (+50ft). There is no level segment until MAP. Company policy overides this to either go miss approach at cMDA, and carry out the missed approach procedure, or be visual and land.
One argument is that this avoids having a heavy jet manoeuvring at low level. Maybe European airspace makes this a more attractive option, for safety/congestion/noise/comfort factors
In corporate, in a light jet, we just flew along until the MAP, as per published procedure.
