Is it pure error or is it runway changes that cause that?It’s probably not so much that people can’t follow the flight director as much as people entering the wrong runway in the FMS and not verifying it. You enter the wrong runway in ATL and it will make for a bad day. This was a problem at my airline like a year and half ago and we were getting a ridiculous number of PDs so much that ATL banned us from doing RNAV SIDs until we could get our act together.
