NavData®
– Jeppesen's aeronautical database to navigate the global
airspace system.
Navigation Data Display
– Display of active waypoint, bearing to
waypoint, and ground track based on active flight plan. The pilot may
also select flight plan information as a mini map (thumbnail map).
These functions are analyzed as part of the GPS WAAS functions not
the PFD functions.
Navigation Log
– Display of navigation information based on active flight
plan, including next waypoint, destination, estimated time remaining,
and fuel totalizer-based range and endurance. This function may be
deselected by a setting in the IDU configuration (limits) file. These
functions are analyzed as part of the GPS WAAS functions not the MFD
functions.
Navigation Mode Signal Output
– Conventional autopilot Navigation
mode signals are the course error output and the left-right deviation
signals. Course error output is based on the difference between the
EFIS selected course (OBS) and the actual aircraft heading. These
signals are based on the selected navigation signal (VOR, GPS).
Nondirectional
– Functions in all directions.
Noodle
– Navigation Display (ND) projected path; curving path based upon
the aircraft bank angle and groundspeed used effectively to assist in
course interception and making small adjustments to bank angle for
proper roll out.
Nanoteslas (nT)
– A unit of measurement of the strength of the magnetic
field. Earth's strongest magnetic field is located at the poles, and the
weakest field is near the equator.
Obstructions Display
– Display of obstructions identified in the embedded
obstruction database which are within 8.5 NM of the aircraft present
position. Non-threatening obstructions are displayed by color to identify
altitude relative to the aircraft’s current altitude (amber [yellow] < 2000’
below, light red < 500’ below, bright red = at or above aircraft).
Threatening obstructions, defined as those that pierce the TAWS
envelope, are identified by highlight when producing a caution and
identified by flashing highlight when producing a warning. The
database used with the obstruction functions meets the integrity
requirements of RTCA/DO-200A.
Omnibearing
– Magnetic bearing of an omni-range station.
Offset
– When referring to parallel track of an active flight plan, “offset”
implies the distance paralleling the original track. When referring to
