Paragraph Functional requirements Explanation<br />
c) The means to show the<br />
following items, either on the<br />
primary field of view of the<br />
pilots, or on a readily<br />
<strong>ac</strong>cessible page display [e.g.,<br />
on a multi-function control<br />
display unit (MCDU)]:<br />
d) The capability to execute the<br />
“direct to” function.<br />
e) The capability for automatic<br />
leg sequencing, displaying<br />
the sequence to the flight<br />
operations where the minimum flight crew is two<br />
pilots, means will be provided for the pilot not<br />
flying (PNF) the aircraft or monitoring pilot (MP)<br />
to check the desired path and the position of the<br />
aircraft relative to that path;<br />
2) A navigation database containing current<br />
navigation data officially issued for civil aviation,<br />
which can be updated in <strong>ac</strong>cordance with the<br />
aeronautical information regulation and control<br />
(AIRAC) cycle and from which ATS routes can<br />
be retrieved and loaded into the RNAV system.<br />
The stored resolution of the data must be<br />
sufficient to <strong>ac</strong>hieve negligible path definition<br />
error (PDE). The database must be protected<br />
against flight crew modification of the stored<br />
data;<br />
3) The means to display to the flight crew the<br />
period of validity of the navigation database;<br />
4) The means to retrieve and display the data<br />
stored in the navigation database relating to<br />
individual waypoints and NAVAIDs, to enable<br />
the flight crew to verify the route to be flown;<br />
and<br />
5) The capability to load on the RNAV system,<br />
from the navigation database, the complete<br />
RNAV segment of the SIDs or STARs to be<br />
flown.<br />
Note.- Due to variability in RNAV systems, this document<br />
defines the RNAV segment from the first occurrence of a named<br />
WPT, tr<strong>ac</strong>k or course up to the last occurrence of a named<br />
WPT, tr<strong>ac</strong>k or course. Legs or segments prior to the first named<br />
WPT or after the last named WPT must not be loaded from the<br />
navigation database.<br />
1) The <strong>ac</strong>tive navigation sensor type;<br />
2) The identification to the <strong>ac</strong>tive (TO) waypoint;<br />
3) The ground speed or time to the <strong>ac</strong>tive (TO)<br />
waypoint; and<br />
4) The distance and bearing to the <strong>ac</strong>tive (TO)<br />
waypoint.<br />
Note.- When the CDU/MCDU is used to support precision<br />
checks by the pilot, said CDU/MCDU must have the capability of<br />
displaying lateral deviation with a resolution of at least 0.1 NM.<br />
