2R AT
When AT is displayed in the line title, the
data in 2R indicates the ETA and distance to
go to the point where the crew should start
the next step climb. NOW is indicated when
this point is passed, or NONE when the
point lies past the 200 nm limit of the T/D.
Line title changes to AVAIL AT when a crew
entered waypoint altitude with an S-suffix is
in the legs that is higher than the maximum
achievable altitude at that waypoint; in this
case, 2R indicates when and where this
S-altitude can be achieved. Line title reads
TO XXX during E/O drift down, whereas
XXX is the target cruise altitude. Line title
reads TO T/D when the aircraft is within
200 nm of the T/D. Data in 2R always refer
to the respective current line title.
3R Destination ETA/FUEL
Indicates predicted ETA and fuel remaining
at the destination, based on the entered or
recommended step climb schedule. Line
title includes ICAO identifier of destination
airport. W/MOD is indicated before the
ETA display when a data modification is
present; in this case, ETA and fuel refer to
the modification.
4R OPT MAX
Indicates the current optimum altitude and
the current maximum altitude.
5R ENG OUT> or ALL ENG>
Selection of ENG OUT> causes the FMC to
change the command speed to the engineout
speed, and to lower the cruise altitude to
the current maximum engine-out altitude
if it is exceeded, in which case a drift down
will be initiated (when the MCP altitude is
reset to that lower altitude). The data are
based on one-engine-out conditions, unless
the FMC detects that two or more engines
are inoperative, in which case the data are
based on those conditions. Performance
predictions will be adjusted accordingly.
—Selection of ALL ENG> changes the
command speed to ECON speed.
6R LRC>
Shown when the command speed is not
in long range cruise (LRC) mode. Selects
LRC speed mode. LRC speed approximately
corresponds to an ECON speed at cost
index 230 under zero wind conditions.
