An airport is not one of the four alternate airports if entered into the alternate
inhibit line.
One or two airports can be entered.
Alternate inhibits can be manually entered or uplinked. The inhibited airports may
be uplinked with the ALTN UPLINK or separately. If uplinked separately, the
CDU help window message ALTN INHIBIT UPLINK is displayed.
Valid entries are airports from the navigation database.
Selecting DIVERT NOW displays the route from the present position to the
selected alternate using the route displayed on the XXXX ALTN page for the
diversion airport. The details of the route can be confirmed or modified before the
diversion is executed.

• deletes all parts of the original route that are not part of the diversion
• if a descent path exists, deletes all descent constraints (the CDU help

displays are selected off of the XXXX ALTN page.
