1. APPENDIX F Troubleshooting Q amp A What is the correct missed approach procedure How do I select the missed approach holding point To comply with TSO specifications the GPS 155 will not automatically sequence to the missed approach holding point The first waypoint in the missed approach procedure will be displayed as the next approach waypoint when the pilot performs a direct to AFTER crossing the MAP which the pilot may activate when authorized All published missed approach procedures must be flown before activating navigation to the holding point To begin the missed approach procedure prior to the MAP the GPS APPR switch must be released from the ARM position to disarm the approach and begin transition of the CDI to the 1 0 nm scale To activate navigation to the first missed approach waypoint after crossing the MAP press Eg then A The GPS 155 will provide direct navigation to the holding point If you do not have direct clearance to the holding point set the GPS SEQ switch to the HOLD position until you have intercepted the inbound course to the holding point See page 68 69 for more on missed approaches How do I re select the same approach or activate a new approach after a missed approach After flying all missed approach procedures you may reactivate the same approach for another attempt from the active route page Once you have been given clearance for another attempt select the starting waypoint
