I agree with CanadianAirbus Pilot..sounds like I flew Airbus for the same Airline
MOT required us to add 50 feet to the MDA, so that during a Go Around, on a coupled/selected approach we would not descend through the published MDA.. The MDA was (is?) considered a hard floor. Descend though it on a Sim ride during the Go around (with no runway in sight) and it could be a Failure, or at least an RS..
