Phraseology for SIDs and STARs

After discussion with stakeholders, it has been decided to temporarily rescind, effective 0000Z May 19th, all SID/STAR phraseology changes made on April 27th. Today’s move was made out of concern over altitude deviations we were seeing in the system and the unforeseen large increase in workload as a result. We are continuing to communicate with airlines, aircraft operators and our employees as we revert back to the phraseology rules that were in place prior to this change.​
