Changes to clearance 2.7.6.1.2

Amendments to initial clearance will be issued any

time ATC deems such action necessary to avoid

possible conflict between aircraft

If you accept a SID as part of your clearance,

comply with all specified routings, altitudes, and

specific restrictions. SIDs must be followed

regardless of weather conditions, unless a

deviation is approved by ATC

Consider SID canceled if aircraft is vectored or

cleared off SID-specified course, unless ATC

adds “expect to resume SID” or otherwise

indicates deviation is temporary

If an altitude to maintain is changed or restated,

either prior to or after departure, you can climb

immediately to that altitude unless ATC states

that altitude restrictions remain in effect. In this

event they would only be changing your

ultimate altitude. The SID path-over-the-ground

must still be followed even though a climb to

higher altitude has commenced
