HOLD AT
When the HOLD function key is pushed and no holding pattern exists in the route, the LEGS page shows prompts to enter the holding fix. Enter the holding fix to show the RTE HOLD page.
Displays a prompt to enter the holding fix, a route waypoint, or present position. A waypoint is entered as the holding fix.
HOLD AT Present Position (PPOS)
Selects the airplane present position as the holding fix. Only displayed during flight when not in a holding pattern.
Modified Route Hold Status
MOD indicates that the holding fix has not been executed.
Execution changes the page title to RTE HOLD (ACT RTE HOLD if holding at PPOS).
FIX
Displays waypoint identifier of the holding fix.
Entry is propagated either automatically from the database, or from a manual entry on the HOLD AT page.
If PPOS was selected on the HOLD AT page, then the FMC assigns PPOS as the fix identifier.
Quadrant/Radial (QUAD/RADIAL)
Displays holding pattern quadrant and radial.
Entry is propagated either automatically from the database, or from a manual entry
on the HOLD AT page.
YA809, YD651 - YK104
(SB changes YA613 - YA687, YC153 - YC413)
The default holding pattern inbound course and turn direction are in small font.
Crew entered or holding patterns extracted from the database are in large font.
Valid entry is XXX (radial) or XX/XXX (quadrant/radial). Valid quadrant entry is
N, NE, E, SE, S, SW, W, NW.
Quadrant shall be determined by the resulting inbound course.

or X (turn direction).
Automatically changes QUAD/RADIAL to agree.
For a flight crew–entered holding pattern, the inbound course is initially the same
as the preceding leg to the fix.
For a flight crew–entered holding pattern, if no entry is made, the FMC assumes
right turns.
LEG TIME
Displays holding pattern leg time.
Valid entry is XXX.X. Manual entry has priority.
If no entry is made, the FMC assumes the standard times of 1.0 minute at or below
14,000 feet and 1.5 minutes above 14,000 feet.

(SB changes YA613 - YA687, YC153 - YC413)
The holding pattern will automatically be resized when climbing or descending
through 14,000 feet if the holding pattern size is not defined in the database or has
not been manually entered.
If a LEG DIST is manually entered, then dashes will be displayed.

Displays current speed and altitude (small font).
Speed or altitude constraint may be entered. Manual entries are in large font and
propagate to LEGS page.
Note: When a cruise hold exists, cruise speed changes propagate around the hold but have no effect on holding speed.

Displays computed time for next passage over holding fix.
