FLYING THE MISSED APPROACH

190-00181-01 Rev. G
• The CDI will guide the pilot through a DME arc.
Just keep the needle centered to fly along the arc.
When using an autopilot, the course select on the
CDI (or HSI) must be periodically updated with
the desired track (DTK).
• When crossing the missed approach point, ‘SUSP’
will appear above the OBS Key, indicating that
automatic sequencing of waypoint is suspended at
the missed approach point, and a ‘from’ indication
will appear on the CDI (or HSI).
Flying a missed approach:
1) Press the OBS Key. The next waypoint in
the approach (MAHP; in this case ‘SWARM’
intersection) is automatically offered as the
destination waypoint.
2) Follow the missed approach procedures, as
published on the approach plate, for proper
climb and heading instructions.
3) An alert message along the bottom of the
display recommends entry procedures for the
holding pattern (e.g., ‘HOLD TEARDROP’).
When flying the holding pattern, a timer
appears on the Default NAV Page. The timer
automatically resets on the outbound side of
the hold when the aircraft turns abeam the
hold waypoint. The timer again resets as the
pilot turns inbound (within approximately 30°
of the inbound course). This allows use of
standard timing (typically one minute) to fly
the inbound and outbound legs of the hold.
4) The GNS 530 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.
