SECTION 6
PROCEDURES
6-9
1) Press the OBS Key. The missed approach
holding point (MAHP; in this case ‘SWARM’
intersection) is automatically offered as the
destination waypoint (Figure 6-21).
Figure 6-21 Missed Approach Holding Point
NOTE: In some cases, an additional hold
waypoint is added to the missed approach
sequence. This additional waypoint is used
as an aid in establishing the holding pattern,
especially where the MAP and MAHP are the
same waypoint.
2) Follow the missed approach procedures, as
published on the approach plate, for proper
climb and heading instructions. The GNS 430
guides the pilot to the holding pattern, along
the 053° radial from LYH VOR.
3) An alert message in the lower right-hand corner
of the screen recommends entry procedures for
the holding pattern (i.e., ‘HOLD DIRECT’, ‘HOLD
PARALLEL’, or ‘HOLD TEARDROP’, see Figure
6-22). When flying the holding pattern, a timer
appears on the Default NAV Page (Figure 6-23).
The timer automatically resets on the outbound
side of the hold when the aircraft is abeam the
hold waypoint. The timer again resets as the
aircraft turns inbound (within approximately
30° of the inbound course). This allows the
pilot to use standard timing (typically one
minute) to fly the inbound and outbound legs
of the hold.

4) The GNS 430 provides course guidance only
on the inbound side of the holding pattern.
When leaving the holding pattern to re-fly
the approach (or another approach) press the
PROC Key to ‘Select Approach?’ or ‘Activate
Approach?’ as previously described. Or, use the
Direct-to Key to select another destination.
