XXXX Alternate Page
Each of the four alternate airports displayed on the ALTN page 1/2 has a related
XXXX ALTN page. The XXXX ALTN pages display specific data about alternate
airports, the route used for a diversion, and the conditions on which the ETA and
fuel calculations are based. All data on the page is related to the alternate airport
displayed in the page title.
Three route options to the airport can be selected:
• DIRECT TO – direct to alternate
• OFFSET – flight plan route with an offset
• OVERHEAD – flight plan route to a waypoint, then direct to alternate
The selected route option has an effect on ETA and fuel remaining. It is identified
by <SEL>. Selection of a route option for one alternate selects the same route
option for the other three alternates.
