always be available and crosschecked in the terminal environment.
7.13.3.1. Data Base Procedures.
7.13.3.1.1. Prior to flight, crews must check navigation database validity. If the
database has expired, the crew:
7.13.3.1.1.1. May continue a mission with an expired database if the
database information required for the flight can be verified with current
flip.
7.13.3.1.1.2. Shall get the database updated at the first opportunity.
7.13.3.1.1.3. May not use the database to fly procedures that require
terminal or better accuracy (i.e. terminal or approach).
7.13.4. Defining Airways
7.13.4.1. Conventional (Overlay) Airways. Appropriately certified RNAV
equipment may be used to fly conventional airways (e.g. FAA J /V routes). These
routes may be either retrieved from the aircraft database or constructed by manually
entering waypoints.
7.13.4.1.1. If within aircraft capabilities, conventional airways should be
retrieved from the aircraft database using the airway identifier.
7.13.4.1.2. If airways cannot be retrieved from the database using the airway
identifier, conventional airways may be constructed by manual entry of associated
waypoints/NAVAIDS. These waypoints/NAVAIDS should be retrieved from the
database by waypoint name if possible. Entry of all airway waypoints is not
required. At a minimum, all compulsory waypoints, all NAVAIDS, and any
waypoint associated with a change in course must be entered. If airways are
entered manually, waypoint sequence must be verified by another crewmember
on multi-crew aircraft.
7.13.4.2. RNAV Airways. RNAV airways should be retrieved in their entirety from
the database using the airway identifier. If entered manually, aircrew must ensure
that all waypoints are entered and flyby/flyover attributes are correctly entered.
7.13.5. RNAV Terminal Area Operations.
7.13.5.1. Some databases may not contain all transitions or departures from all
runways. Terminal area and instrument approach procedures must be retrieved in
their entirety from the navigation database. These procedures may not be modified or
entered manually.
7.13.5.2. Prior to commencing a terminal area or instrument approach procedure,
crews must confirm waypoint name, sequence, course, distance, and altitude
information match charted information (to include the missed approach segment).
Waypoint type (flyby vs. flyover) should also be confirmed if this information is
available.
7.13.5.3. In the event of differences between the terminal procedure chart or
approach chart and database, the published approach chart, supplemented by
