5-13-2. EN ROUTE MINIMUM SAFE ALTITUDE WARNING (E-MSAW)

1. When an E-MSAW alert is displayed, immediately analyze the situation and take the appropriate action to resolve the alert.

   NOTE: Caution should be exercised when issuing a clearance to an aircraft in reaction to an E-MSAW alert to ensure that adjacent MIA areas are not a factor.

   • REFERENCE
   • FAA Order JO 7110.65, Para 2-1-6, Safety Alert.
2. 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:
   1. The specific alert suppression message may be used to inhibit the E-MSAW alerting display on a single flight for a specific alert.
   2. 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.
      • NOTE:
      • 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.
3. 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.
