+All  approach  procedures  to  be  flown must  be  retrievable  from  the  current  airborne navigation  database  supplied  by  the  equipment manufacturer  or  other  FAA−approved source. The system must be able to retrieve the procedure by name from the aircraft navigation database, not just as a manually entered series of waypoints. Manual entry of waypoints using latitude/longitude or place/bearing is not permitted for approach procedures.

+Prior to using a procedure or waypoint retrieved from the airborne navigation database, the pilot should verify the validity of the database. This verification  should  include  the  following  preflight and inflight steps:
+  - [a] Preflight:
+    - [1]  Determine the date of database issuance, and verify that the date/time of proposed use is before the expiration date/time.
+    - [2]  Verify that the database provider has  not  published  a  notice  limiting  the  use  of  the specific waypoint or procedure.
+  - [b] Inflight:
+    - [1]  Determine  that  the  waypoints and transition names coincide with names found on the procedure chart. Do not use waypoints which do not exactly match the spelling shown on published procedure charts.
+    - [2]  Determine that the waypoints are logical  in  location,  in  the  correct  order,  and  their orientation to each other is as found on the procedure chart, both laterally and vertically.
