13-1-9. ACKNOWLEDGEMENT OF
AUTOMATED NOTIFICATION
a. The URET Inappropriate Altitude for Direction
of Flight (IAFDOF) feature shall be used in the
automatic mode (i.e., IAFDOF Manual shall remain
deselected) unless otherwise authorized in a facility
directive.
b. Completion of any required coordination for
IAFDOF shall be acknowledged on the ACL by
removing the IAFDOF coding.
c. Completion of appropriate coordination for an
Unsuccessful Transmission Message (UTM) shall be
acknowledged on the ACL by removing the UTM
coding.
d. Issuance of the Expect Departure Clearance
Time (EDCT) to the pilot or other control facility
shall be acknowledged on the DL by removing the
EDCT coding.
e. IAFDOF, UTM, or EDCT coding shall be
acknowledged only after the appropriate action has
been completed.
f. Send/acknowledge Host Embedded Route Text
(HERT) coding only after the appropriate clearance
has been issued to the pilot or otherwise coordinated.
Do not send/acknowledge HERT unless the sector
has track control for the flight or it has been otherwise
coordinated.
g. Remove ATC Preferred Route (APR) coding
only after the route has been checked and any
required action has been completed. Do not remove
APR coding unless the sector has track control or it
has been otherwise coordinated.
NOTEIf
coding is prematurely removed and the control of the
aircraft is transferred before completing the appropriate
action, the next sector may not receive the necessary APR
notification.
13-1-10. CURRENCY OF TRAJECTORY
INFORMATION
a. The sector team shall perform automation
entries in a timely manner.
NOTE-
1. Conflict probe accuracy requires timely updates of data
used to model each flight's trajectory. If this data is not
current, the aircraft entries and notification of probe
results for surrounding sectors and facilities, as well as the
subject sector, may be misleading.
2. Data used to model an individual aircraft's trajectory
includes route of flight, assigned and interim altitudes,
application/removal of an adapted restriction for that
flight, and aircraft type.
b. An exception to the requirement to enter or
update interim altitudes may be authorized for certain
ARTCC sectors if explicitly defined in an appropriate
facility directive.
NOTEURET
accuracy in assigning alert notification is
dependent upon entry/update of a flight's interim altitude.
13-1-11. DELAY REPORTING
a. Adhere to all applicable delay reporting
