The OBS Key is used to initiate the missed approach, as follows (refer to Figure 6-21 for the following steps): 1) Press the OBS Key. The missed approach holding point (MAHP; in this case 'SWARM' intersection) is automatically offered as the destination waypoint (Figure 6-22). SECTION 6 PROCEDURES 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. Figure 6-22 Missed Approach Holding Point Figure 6-23 'Hold Teardrop' Annunciation 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 GNC 420 provides guidance 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 6-23). When flying the holding pattern, a timer appears on the Default NAV Page (Figure 6-24). 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 Figure 6-24 Hold Timer 4) The GNC 420 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.) 190-00140-20 Rev. K GNC 420(A) Pilot's Guide and Reference 6-9
