Aircraft; Procedure
[Aircraft X] assigned the ANC8 SID climbing and making the right turn. The system initiated a Low Altitude notification. I issued a Low Altitude Alert to the pilot with an immediate right turn and climb. The pilot completed the turn/climb and entered a safer terrain environment. The ANC8 SID could include a DME arc as part of the procedure to give pilots a finite boundary not to cross. This could alleviate confusion about the wording of the departure. Some autopilots do not appear to fly the procedure in a safe manner. I believe the autopilot would better interpret a DME arc; instead of relying on the pilot to catch the footnote about required heading establishment.
A11 TRACON controller reported air carrier on ANCHO8 SID entered higher MVA resulting in low altitude alert.
