Is there a “grace period” of, say, 2 kts above 250 below 10,000? Meaning you can go up to 252 kts before getting a warning.
If there’s not, I feel like there should be one because in real life ATC is not likely to ask about 1-2 kt overspeeds. Plus, if you put 250 as your speed below 10,000 it has the tendency to go to 251.
Note: The reason I’m asking is because I haven’t tested it out myself yet.
