NOTE:
When a procedure is deleted from the flight plan, the original flight plan is
correctly restored since the duplicate waypoint is only skipped and not
deleted.
Navigation databases should be current for the duration of the flight. If the
Aeronautical Information Regulation and Control (AIRAC) cycle is due to
change during the flight, operators and pilots should establish procedures
to ensure the accuracy of navigation data including suitability of
navigation facilities used to define the routes and procedures for flight.
Once acceptable means to compare aeronautical charts (new and old) to
verify navigation fixes prior to departure, electronic data have traditionally
been verified against paper products. If an amended chart is published for
the procedure, do not use the database to conduct the operation.
There may be a slight difference between the navigation information
portrayed on the chart and the primary navigation display heading.
Differences of three degrees or less may result from equipment
manufacturer’s application of magnetic variation and are operationally
acceptable.
GPS receivers do not “fail down” to lower levels of service once the
approach has been activated.
If only
appears, use the LNAV minima if the rules under which the
flight is operating allow changing the type of approach being flown after
commencing the procedure. If the lateral integrity limit is exceeded on an
LP approach, a missed approach is necessary, since the lateral alarm
limit may not be reset while the approach is active.
