Predetermined radio calls to SOSA on 122.825 will be broadcast by West jet crews when they are inbound to Hamilton. As shown at the CAS Seminar this spring, Westjet traffic overflies the TETOS intersection (basically Plattsville) southbound and then turn east direct Hamilton. West jet pilots will make the following radio broadcast:
"Rockton Traffic WestJet XXX over Plattsville at 8000 ft, in descent landing YHM in 18 minutes".
This broadcast is meant for information only, do not respond to it. Once the tranmission has been made, they will be going back to their IFR frequency.
What this means to our operations is that you should now be looking out for 737 traffic inbound from the west to Hamilton and descending from 8000, down to about 3500 by St George.
