Key Takeaways:

The author undertook an extensive and costly avionics upgrade for his aging Piper Arrow due to safety concerns and equipment failures, which resulted in a "domino effect" of component replacements and a redesigned instrument panel.
A primary challenge identified was how to effectively and safely train on the customized, complex new technology, a stark contrast to the standardized training available for airline cockpits.
Training involved manuals, online videos, and manufacturer-specific courses (some paid), leading the author to suggest a formal FAA logbook entry requirement for pilots to document proficiency with new avionics before flying in instrument conditions.

When my wife agreed to an extensive avionics upgrade to our Piper Arrow, I was pleased that she immediately understood the safety value of the endeavor despite the eye-watering cost. Based on our experience of a vacuum pump failure, an intermittent dual comm failure, and the fact that the entire system was aging, it was time for a change.

Avionics shops don’t just install a standard instrument panel template for a 54-year-old airplane. It’s a carefully thought-out strategy of integrating the new with the old, dependent almost completely on customer desire and budget. Selection and placement of the electronics is a la carte. Although the shopping process to determine the best value for our airplane was exciting, it alerted me to an interesting challenge.
