NOTE: See NAS-MD-678 for the EARTS conflict suppress message.
NOTE: Special military operations where the SG function would typically apply involve those activities where military aircraft routinely operate in proximities to each other that are less than standard en route separation criteria; i.e., air refueling operations, ADC practice intercept operations, etc.
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.
NOTE: A facility directive may be published, in accordance with JO 7210.3, Paragraph 8-2-7, Waiver to Interim Altitude Requirements, deleting the interim altitude computer entry requirements of subpara 3(b).
This information must not be modified outside of the controller’s area of jurisdiction unless verbally coordinated or specified in a Letter of Agreement or Facility Directive.
Whenever Mode C altitude information is either not available or is unreliable, enter reported altitudes into the computer as follows:
NOTE: Altitude updates are required to assure maximum accuracy in applying slant range correction formulas.
The display of Mode C targets and limited data blocks is necessary for application of Merging Target Procedures. Sectors must ensure the display of Mode C targets and data blocks by entering appropriate altitude limits and display filters to include, as a minimum, the altitude stratum of the sector plus:
The use of the OK function is allowed to override sector eligibility only when one of the following conditions is met:
Do not use coast tracks in the application of either radar or nonradar separation criteria.
NOTE: The ERAM hold message allows automatic calculation and reporting of aggregate delays.
Sector controllers shall ensure the situation display accurately reflects the status of all SAAs that impact their area of control responsibility. When “SAA DOWN” is displayed in the Outage View, manually create visual indicators on the situation display to reflect changes to airspace status.
NOTE: The “SAA DOWN” message in the Outage View means that SAA status is no longer being updated. The status of each SAA at the time of the failure, whether “on” or “off”, will continue to be displayed. Status changes will not be automatically updated on the display until the outage is resolved.
