defined in the same manner except for the type of terminator of the
leg. The FMS will fly each of these legs as follows:
1. HA (Hold to an altitude terminator) - The aircraft will stay in
the holding pattern until the specified altitude is reach then
sequence to next leg the next time it crosses the holding fix.
HA type holding are generally found in SIDs.
2. HF (Hold to a fix terminator) - The aircraft will sequence to
the next leg after crossing the holding fix the second time.
HF holding patterns are usually used as course reversals in
lieu of procedure turns.
3. HM (Hold to a manual terminator) - The aircraft will remain
in the holding pattern until an action is taken by the pilot to
depart. HM holding patterns are most commonly found at
missed approach holding fixes and are the only type of
holding patterns the pilot can program manually.

MANUALS AFFECTED: Universal Avionics Systems
Corporations’ Operator’s Manual, Report No. 2423sv602,

FILING INSTRUCTIONS: Insert this Temporary Change into
2423sv602, Section 5 adjacent to page 5-46.

the last paragraph under “Holding Patterns”.
Refer to the ARRIVAL Section, Approach Procedures for information
about automatic and manual holding pattern termination.

Holding Pattern Depiction on NAV and FPL Pages
Holding pattern definitions and terminators are displayed below as
they appear on NAV and FPL pages. Holding fixes are designated
as overfly waypoints on the pages. An asterisk “*” appears following
the waypoint on these pages. The letters HLD, proceeded by a turn
direction arrow and followed by the inbound course designates the
holding pattern. A “T” or “°” follows the course and indicates true or
magnetic respectively. The terminator will be depicted as an altitude
for HA legs, a waypoint name for HF legs and (HOLD) for HM legs.
The following are examples:

When a holding pattern is defined at a fix on the flight plan it may be
either armed or directly activated. If armed (ARM HOLDING) the
aircraft will continue to fly the flight plan and enter holding upon
reaching the holding fix. If directly activated (DTO HOLD) the
aircraft will proceed directly to the holding fix and commence
holding. If the fix is not on the flight plan, the hold may only be
directly activated. Once established in the pattern, the FMS will fly
the correct legs, compensating for existing wind conditions.
Estimated Time of Arrival (ETA) over the holding fix is constantly
displayed.
Holding Pattern Depiction on HOLD FIX, NAV LEG And DTO
Pages
Waypoints with holding patterns associated whether obtained from
the procedural data base or pilot defined are depicted as follows.
The “*” designates the waypoint as a fly-over waypoint while a
subsequent waypoint designating an HX leg follows with a “/H” to
indicate the hold.
