For context, most commercial airline pilots use autoland infrequently, around 1% to 2% of landings, or less. However, during low visibility conditions (fog), autoland is sometimes mandatory to be able to land at all.<p>In manual landings, I could expect that radio altimeter interference can still disturb the altitude callouts and terrain warnings.
