Ask the IFR Expert: What do I do when the avionics glitch?

Modern IFR panels are incredibly capable, but they’re still computers—and sometimes they glitch at the worst possible moment. When automation stumbles in IMC or during a high-workload phase, I fall back on a simple sequence: stabilize, simplify, and strategize. First, I make sure the airplane is under control—pitch, power, trim, or a healthy autopilot if it’s available. A stable airplane buys the time needed to think clearly.

Next, I sort out what still works. One component may hiccup while the rest of the panel is fine, so I shift my scan to the instruments and sources I can trust. I’m not trying to fix anything immediately—just separating good data from bad so I can operate confidently for the next minute or two.

Only then do I bring ATC into the loop. A simple request for vectors or a level-off is usually all it takes to create breathing room. I had this happen recently on departure when the FMS suddenly believed we were somewhere we definitely weren’t. Navigation was not possible instantly. We leveled off, stabilized the airplane, and explained the issue to ATC. They were more than willing to give us vectors while we reset the system and eventually continued on our way.

The lesson is straightforward: keep the airplane steady, identify reliable instruments, and don’t hesitate to ask ATC for help early. Time and space are often the best backups you have when the glass starts acting up.

It was his first airplane trip at age seven that made Eric decide to become a pilot. "While boarding the airplane, a flight attendant noticed my interest in the flight deck and urged me to go talk to the pilot. I give a lot of credit to that pilot for my career choice." Eric earned a bachelor’s degree in finance and went on to an airline career. He learned to fly at Sporty’s as part of the University of Cincinnati’s Professional Pilot Program, an initiative he later directed.Eric now manages Sporty’s media network including FlightTrainingCentral.com. In addition, Eric serves as a Captain in a Cincinnati-based corporate flight department.
