GPS failures, stemming from external jamming, internal loose connections, or unseated units, can lead to loss of navigation, terrain awareness, and inadvertent airspace violations.
Pilots should actively mitigate risks by checking GPS NOTAMs and RAIM pre-flight, remaining vigilant for warning messages, practicing terrestrial navigation, and giving ample clearance to airspace.
Troubleshooting in-flight is limited; ensure thorough preflight inspection of avionics, utilize backups, contact ATC for assistance, and report any GPS outages or incidents promptly.
These pages often contain encouragement to pilots not to become so completely reliant on GPS that its loss constitutes no less than an emergency. GPS, both panel-mount and portable, can fail for external and internal reasons. Read about these GPS-failure events culled from ASRS reports. We hope this article will lead you to get some practice using terrestrial nav.
