Buyers who shop a new Mooney Acclaim will inevitably at least consider the Cirrus SR22 and Columbia, too. My perspective is as a CFII-my business is training pilots in technologically advanced aircraft (TAA) with a focus on Cirrus and Columbia. Here are some highlights from the right seat. Garmin vs. Avidyne: Cirrus airplanes are available with only the Avidyne Entegra while Columbias can be ordered with either the keyboard-equipped Garmin G1000 or the Entegra. By far, more owners are specifying the G1000 for the Columbia, but there are still more Avidyne Columbias flying. Which is better is a matter of personal taste. The Avidyne is simpler and easier to use, but the G1000 has more advanced capability, including interface with its own dedicated autopilot, the GFC700. Further, the Garmin has full screen reversion in the event of failures, the Avidyne doesnt.
