Meaning of " Do not exceed..."

Hello IFC members, hope you all having great Day/Night.

So I had an approach tell me to not exceed certain speed.

Example : “IFB033 Do not exceed 180 knots”

My Question : So does this mean that I’ve to set my speed below/above what the approach controller told me?



“Do not exceed” measn you shouldn’t go any faster than the assigned speed.

It means don’t go faster than 180 knots. So set your speed below than 180 knots.

So what if set to 180 ( the speed that the controller set me up ) is that acceptable?

If controller tells you „Do not exeed 180kts“, the maximum speed you’re allowed to fly is 180kts, so that’s acceptable.

In other words: 180 is acceptable. 181 is not acceptable anymore.

Let me just add that even though ATC sees groundspeed, the speed commands apply to airspeed.


Yep, I know ATC only sees Ground Speed but thanks anyway :)
