GPS Navigation
Following VOR navigation, today is dedicated to GPS navigation. Because the GPS can accurately determine one’s position in real time, and depict it on a moving map, it would seem that GPS navigation should be a walk in the park. In reality, with power comes responsibility, and the increased situational awareness offered by GPS navigation comes at a price: one must master the complexity of the Garmin GNS 430, and also make sure that GPS satellites will still provide accurate information when time comes to initiate a GPS approach. The later is achieved through a RAIM prediction, which tells the pilot whether enough satellites will be available from any given location, at any given time in the future. We logged 1.8 hours and 2 instrument approaches.
