The controller may suppress the display of an E-MSAW alert from his/her control position with the application of
one of the following suppress/inhibit computer functions:
The specific alert suppression message may be used to inhibit the E-MSAW alerting display on a single flight
for a specific alert.
The indefinite alert suppression message must be used exclusively to inhibit the display of E-MSAW alerts on
aircraft known to be flying at an altitude that will activate the alert feature of one or more MIA areas
within an ARTCC.
1. The indefinite alert suppression message will remain in effect for the duration of the referenced
flight's active status within the ARTCC unless modified by controller action.
2. The indefinite alert suppression message would typically apply to military flights with clearance to
fly low-level type routes that routinely require altitudes below established minimum IFR altitudes.
The computer entry of a message suppressing or inhibiting E-MSAW alerts constitutes acknowledgment for the alert
and indicates that appropriate action has or will be taken to resolve the situation.
