5L and 5R
-- The current navigation mode of the flight management
system (FMS) is displayed on 5L and 5R. In the following example,
the FMS is navigating using the global positioning system (GPS) as
the primary navigation sensor. The required accuracy of the
navigation mode for the current phase of flight is reflected in the
required navigation performance (RNP) value in nautical miles
(NM). Estimated position uncertainty (EPU) values indicates
estimated navigation accuracy of the current navigation mode.
When EPU becomes larger than RNP, UNABLE RNP is displayed
in the scratchpad. In addition, the navigation (NAV) radios are tuned
to the navaid INW (frequency 112.60). The
A
preceding the navaid
identifier indicates the radio is in autotuning.
D
6L and 6R
-- These prompts give access to the NAV 1 and NAV 2
pages. These pages list the 10 closest navaids to the aircraft.
