Everyday Partial Panel

My story involving a glass-panel failure happened with an Avidyne unit. I was at Wick, Scotland, lining up for departure, and suddenly things started failing. First the lower Garmin 430, then the upper one. The transponder quickly followed and by then the PFD looked like a demo poster for what happens when things fail. The great news was that I was on the ground-even without a radio. It turned out the number one alternator and the master control unit had failed. Whether one had caused the other was incidental at that point. In marginal weather, with no radio, only the most basic of flight instruments and no VOR or other electronic guidance? I surely wasnt taking off; being airborne and trying to land would have been harrowing. My handheld GPS had just become my new best friend; Ive double-checked its batteries ever since. Between it and my Sportys handheld nav/com (yes, I keep those batteries fresh, too), I would have had a shot at getting down in one piece. We might carry some backup radios and gadgets, but how prepared are we to deal with major system outages when in the clag? Short of the odd IPC or checkride, how often do we practice for-real panel failures? Why not use everyday flying to stay sharp on partial panel?

Key Takeaways:

• Modern aircraft, including those with glass panels, can experience significant instrument failures, highlighting the critical need for backup systems and pilot preparedness.
• Proficiency in "partial panel" flying, which involves navigating using only basic instruments like the turn needle, ball, and airspeed, is essential for pilots to safely manage in-flight instrument failures.
• Regular practice of partial panel skills, whether through covering instruments or mindful observation, is crucial for maintaining pilot precision, enhancing safety, and building confidence for real-life emergencies.
