CROSS (FIX) AT OR ABOVE (ALTITUDE).

CROSS (FIX) AT OR ABOVE (ALTITUDE)

Used by ATC when an altitude restriction at a specified fix is required. It does not prohibit the aircraft from crossing the fix at a higher altitude than specified; however, the higher altitude may not be one that will violate a succeeding altitude restriction or altitude assignment.
