ATC speed instruction

Hi all,

Quick question: When an ATC controller is instructing you to go below a certain speed is this in airspeed or groundspeed?

This is the Airspeed that they’re referring to.


Yep as deercrusher said it’s Air speed. Not to be confused with what they can see which is ground speed.

Thanks, I just saw you at LXGB I was the airbus A320 TAP landing after you ;)
