Ever Check Your VOR?
We all learned about it during our initial instrument training, but that may well be the last time you actually did it. This could be a deadly problem.
We learned 14 CFR §91.171—the “VOR Check” rule—during instrument ground school. In this era of satellites and GNSS, this rule is often overlooked as VORs become just named fixes instead of navigation beacons. Even with the latest navigation equipment, however, 91.171 can rear its head from time to time.
