In other news, the C172 did actually feel quite different to fly. Compared to the Aquila it felt steadier in the turbulence, but also a bit more sluggish on the controls. I felt I had to work a bit more to maneuver it.
However, it was very cool to engage the autopilot and see how it worked to keep course and altitude. I'll have another round with the instructor next week, to work on landings (we didn't get enough time today to do many landings, and the conditions were a bit rough). Other airwork, and operation of the digital cockpit, was fine.
