or three digits are required to input an
altitude (that is, enter 30A and 3000A
will be displayed). Full digit entry may
be used to enter an altitude. Altitudes
less than 1000 feet are entered with a
preceding zero (that is, enter 054 and
54 feet will be displayed). Any altitude
entered greater than the transition
level is converted and displayed as

nautical miles (-99 to +99 range). If
offset is prior to the waypoint, enter
the range value and a (-) will pre-fill as
a default. Enter a (+), then the range

The FPA value field pre-fills with the
default value programmed on the VNAV
Data page if this waypoint was accessed
from the Flight Plan page. If accessed
from the NAV or Direct To page, the field
pre-fills with the DIR value. If an FPA is
manually entered, the FPA type field
changes to MAN.
To cancel the FPA, insert 0 then press
ENTER key. The field changes to dashes,

When SID's, STAR's, or approaches have altitude
constraints at waypoints on the procedure the system
automatically loads the altitude constraints on the
active flight plan. The system will not load any except
to cross altitudes on the Active Flight Plan page.
