Line 6L INSERT. Inserts hold into the flight plan.
Line 1R TIME/DIST. Time (minutes) and leg distance of the holding pattern.
Default time is 1.0 minute at or below 14,000 ft. and 1.5 minutes above 14,000 ft.
The altitude used to determine this is the predicted altitude at the revise point when
HOLD page was accessed. For a PPOS HOLD, the aircraft altitude at the time the
FROM point was accessed is used. Either time or distance may be entered as the
leg defining parameter but not both.
NOTE: The time of a holding pattern with a default time of 1.5 minutes
will not be automatically modified to 1.0 minute when the aircraft
descends to an altitude at or below 14,000 feet. The time may be
modified on data line 1R of the holding page.
Line 2R REVERT TO STANDARD. Return to default hold parameters in
existence before alteration by the crew. REVERT TO DATABASE is displayed
when the hold parameters from the NAV database are modified and inserted by
the crew. Selecting 2R causes previously displayed data to return.
Line 3R LIMIT UTC/FUEL. Calculated values in large font are shown and pilot
entry is not allowed. Dashes displayed if value not available.
LIMIT UTC - Predicted value at which FOB is equal to LIMIT FUEL. LIMIT
FUEL - Fuel necessary to complete the flight plan with no changes to fuel
reserves. LIMIT FUEL = TRIP + RTE RSV + ALTN + FINAL.
The entry in 3R is not displayed until the holding pattern is inserted in the F-PLN.
Then it is displayed on both the F-PLN and the HOLD page. Pushing 6L
*INSERT inserts the holding pattern into the flight plan.
Line 4R ALTN/FUEL. Alternate airport and the fuel to fly from the destination
airport to the alternate airport. If there is no alternate, NONE is displayed but a
fuel entry may be entered.
Line 5R CLR ALTN. Displayed if an ALTN destination exists and the revise point
is in the primary portion of the F-PLN. Pushing 5R when the prompt is displayed
deletes the alternate destination and route legs setting ALTN fuel to zero.
FMS maximum holding airspeed is ICAO limited as follows:
• Up to 14,000 - 230 KIAS
• 14,000 to 20,000 - 240 KIAS
• 20,000 to 34,000 - 265 KIAS
• Above 34,000 - .83 Mach.
During an HM or HF hold, when localizer or VOR mode is captured, an automatic
*EXIT AT FIX button push will occur.
