5 - PROCEDURES89Approach with HoldThe OBS key is used to initiate the missed approach,as follows:1. Press the OBS key after the SUSP annunciatorappears. If you press the OBS key a secondtime, the missed approach holding point(MAHP; in this case “SWARM” intersection)is automatically offered as the destinationwaypoint.NOTE: In some cases, an additional holdwaypoint is added to the missed approachsequence. This additional waypoint is used as anaid in establishing the holding pattern—especially where the MAP and MAHP are thesame waypoint.2. Follow the missed approach procedures, aspublished on your approach plate, for properclimb and heading instructions. The 400W-series unit will guide you to the holding pattern,along the 053° radial from LYH VOR.3. An alert message in the lower right hand cornerof the screen will recommend entry proceduresfor the holding pattern (i.e., “HOLD DIRECT”,“HOLD PARALLEL”, or “HOLD TEARDROP”).As you fly the holding pattern, a timer appearson the default NAV page. The timer automati-cally resets on the outbound side of the holdwhen you are abeam the hold waypoint. Thetimer again resets as you turn inbound (withinapproximately 30° of the inbound course). Thisallows you to use standard timing (typically oneminute) to fly the inbound and outbound legsof the hold.4. The 400W-series unit will provide course guid-ance only on the inbound side of the holdingpattern. When leaving the holding patternto 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 anotherdestination.)Flying an Approach with a HoldStarting where the previous example left off,we’ll assume weather conditions resulted in a missedapproach at Lynchburg Regional. Now, you’ve decidedto divert to Farmville Regional (KFVX) instead.1. Press direct-to.2. Use the small and large right knobs to enterthe destination airport’s identifier (KFVX).
