Autopilot level-off at MDA
If you are doing the traditional "Dive and Drive" method on a non-precision approach with the Autopilot Coupled, i.e. VS Mode, does any plane/company require an additive to the MDA due to the tolerances of the Autopilot capture/hold capabilities?

I wouldn't think that you would have to, but I ran into a "technique" (not sure that it is driven by any credible technical data) for specific plane that has that.
Hope more chime in to see if anyone at all does it.

Every glass airplane I've flown had the ability to put in the exact MDA (or at least rounded to 10 feet) and the autopilot would level off there. So, I don't think it's a very accurate statement to say "most operators round up to the nearest 100 feet". Some do, many don't.
The other thing to consider is, in 2018, I would say that "most operators" aren't doing dive and drive approaches any longer.

The POH/AFM/Autopilot supplement will state what the limits are for the autopilot, in other words, what you can use it for. if it says you can go down to MDA or DH, you can do exactly that. If there are any quirky limitations, they'll be stated.
