Whether for backing up a GPS navigator or serving as a primary and one-and-only radio, the digital navcomm radio is far from extinct. It could actually be making a comeback.
That’s because there have been increasing concerns of GPS signal outages, and manufacturers and avionics shops tell us that’s creating more interest in VHF navcomm installations. Honeywell even recently released a new model to replace the popular analog KX155. Last year Trig Avionics brought a fresh digital model to the market and it’s been a brisk seller.
