When Garmin went public with its Emergency Autoland system for the Piper M600 turboprop in 2019—the first of several OEM type-certified applications that followed—it was natural to ask about the possibility of retrofit installations.
At the time, Garmin was noncommittal, saying that while it would be technically possible to bring the automation to the aftermarket, it wasn’t planning to do so—yet. Turns out the engineering for a retrofit Autoland was already in progress, while working with Piper on the M600 type certification.
