So it seems like i hear something new on this from different people i work with anytime i had asked this. Dont have any of the pubs in front of me right now and am just curious on what a pilot has to read back to you. I was pretty sure it was clearence instructions and not sure if that was it or not. When clearing an a/c to land does the pilot have to readback then? What about taxing them out to the runway? Thanks
