Section 2. Procedures
8-2-1. SINGLE SITE COVERAGE STAGE A OPERATIONS
Facilities may adapt all sort boxes within 40 miles of the
antenna to that site as preferred and with the single site
indicator set to permit the use of 3 miles radar separation as
defined in FAAO JO 7110.65, Air Traffic Control, subpara
5-5-4b3, Minima. This adaptation may be used provided:
significant operational advantage will be obtained using
single site coverage. Consideration must be given to such
aspects as terminal interface, radar reliability, etc.; and
directives are issued to:
areas within 40 NM of any radar site in which the adaptation
has been modified.
3 NM separation in the modified area.
local procedural changes.
8-2-2. ADAPTED ALTIMETER SETTINGS
a current altimeter setting from the adapted reporting station
for each radar sort box or geographic area is input into the
center's computer. When an altimeter setting for an adapted
reporting station cannot be obtained, enter the altimeter
setting from the appropriate alternate reporting station.
8-2-3. ADAPTATION OF EXTERNAL ALTIMETER SETTINGS
Adaptation of altimeter settings for reporting stations
outside a facility's area is optional up to the maximum number
listed in the NAS adaptation specifications.
8-2-4. CONFLICT ALERT FUNCTION PARAMETERS
the nominal value of parameters specified in NAS Configuration
Management Documents for the CA function unless a waiver to
adjust parameter value is received from the En Route and
Oceanic Safety and Operation Support Office.
air traffic managers are authorized to inhibit the display of
CA at specified sectors.
8-2-5. MODE C INTRUDER (MCI) ALERT PARAMETERS
the nominal value of parameters specified in the NAS
Configuration Management Document for the MCI Alert function,
except the base altitude parameter, unless a waiver to adjust
parameter value is received from the En Route and
Oceanic Safety and Operations Support Office.
b. MCI Alert base
altitude must be set at any value between ground level and
5,000 feet MSL at the discretion of the facility air traffic
manager. When a facility's or sector's ground level is above
5,000 feet MSL, base altitudes may be set to 1,500 AGL. Any
instance of base altitudes above 5,000 feet MSL must be
documented and forwarded to the En Route and Oceanic Safety
and Operations Support Office through the respective Service
Area Operations Directorate.
air traffic managers are authorized to temporarily adjust the
Mode C Intruder Alert base altitude at a sector(s) when
excessive MCI alerts derogate the separation of IFR traffic.
For the purpose of this section, temporary is considered to be
of less than 4 hours duration, not necessarily continuous,
during any calendar day. The following is required when MCI
base altitude is adjusted:
each occurrence when this procedure is used on FAA Form
7230-4, including the sector and temporary altitude.
must be forwarded according to subpara b above, if it is
determined that a temporary adjustment of the MCI base
altitude does not meet the needs of the sector.
air traffic managers are authorized to inhibit the situation
display of MCI Alert at specified sectors.
8-2-6. E-MSAW ADAPTATION
that all internal airspace is adapted for E-MSAW processing.
Ensure that the altitude information adapted in the polygons
agrees with the MIA sector charts and that the automation is
adapted in accordance with the appropriate NAS Management
8-2-7. WAIVER TO INTERIM ALTITUDE
sector conditions; e.g., heavy traffic or sector complexity,
preclude meeting the requirements of FAAO JO 7110.65, Air
Traffic Control, subpara 5-14-3b, Computer Entry of Assigned
Altitude, ARTCC air traffic managers may authorize the
deletion of the requirements if an operational advantage is
gained. A facility directive must be issued with instructions
governing permissible procedures. It must contain:
where the waiver applies.
procedures if required.
instructions to input a reported altitude for non-Mode
C-equipped aircraft when it will operate at an altitude before
proceeding to the assigned altitude.
