The FAA will discontinue the use of the dedicated Flight Watch radio frequency 122.0 MHz on September 24, a week earlier than the previously announced end date for the En Route Flight Advisory Service (EFAS) frequency.
The FAA changed the implementation date to September 24 from October 1 because all necessary preparations will be completed earlier than planned. Services provided by EFAS will continue to be offered over published Flight Service frequencies and on 122.2 MHz, the universal frequency for contacting Flight Service.
After its discontinuation, 122.0 MHz will be monitored for six months so pilots may be directed to other frequencies appropriate for their flight.
