The excellent FAA document…. “Pilot/Controllers Procedures & Systems Integration Work Group Climb Via/Descend Via Speed Clearances Frequently Asked QuestionsPilot/Controllers Procedures & Systems Integration Work Group” ….Is no longer available online, has there been any significant change to USA climb via / descend via procedures.Specifically is this still the case…. “12 Q. What if I receive a “Cleared” or “Cleared Via” clearance; am I permitted to descend to meet any published altitudes? A. NO. Only a “Descend Via” clearance gives you the vertical authorization. The other two examples are a “lateral” clearance. Note: Compliance with published speed restrictions are required, unless canceled or modified by ATC.”
Is the removed document the same as this one?
