I just came across what appears to be an error in the CHINS5 STAR data for KSEA. The KSEA terminal procedures file has the waypoint SNOMY after RADDY, while the current chart lists HUMPP N47 degrees 12.56' W121 degrees 48.61' after RADDY. (SNOMY does not appear on the current chart.) This error has been in the terminal procedures file since at least cycle 0509.I do happen to have an old CHINS2 arrival chart that uses SNOMY rather than HUMPP. I don't know when the change to use HUMPP was made.Don S.

>I just came across what appears to be an error in the CHINS5>STAR data for KSEA. Hi Don.You seem to have found an error in the DAFIF data. The printed chart I has does indeed show HUMPP but the DAFIF digital data I use has SNOMY. Thanks for reporting the error. I will inform NGA of the error and have the intersection corrected in the next cycle. RegardsTerry

Thanks Terry!
