Differences

Everyone remembers the first airplane they flew. But what about the second one? Chances are it was a lot like the first one, but still was different. While the make and model may have been the same, the serial and registration numbers were different, of course. Even trivial differences between the two likely was a topic of discussion with your instructor. The conversation may have included how different avionics equipment was installed, or one of them never had a working landing light, or had a prop offering better performance. In an extreme, you could have been mixing makes, models, wing position and avionics. There likely was a moment where you couldnt find that blemish on the windshield you used as a reference point, or found the throttle too stiff.

Key Takeaways:

A fatal accident involving a Cessna 172M was caused by the pilot's failure to retract wing flaps before takeoff, attributed to a lack of familiarity with the aircraft make and model.
The pilot's primary flight experience was in a Cirrus SR20, which has a different flap control system and uses a 50% flap setting for takeoff, contrasting with the Cessna 172M's requirement for flaps to be up.
The article emphasizes the critical need for comprehensive "differences training" when pilots transition to different aircraft types, ensuring understanding of varied controls, performance, and standard operating procedures like flap usage.

In my case, the second airplane I ever flew was a Piper PA-28-140, a Cherokee 140. I was still a student, having soloed in a Cessna 150. Since the 140 had something resembling a back seat, it was a big deal. After some dual and once I was out of the traffic pattern, my first thought was, “Do I remember how to land this thing?” It had only one door, much stiffer rudder pedals, Johnson bar flaps, a two-piece windshield and a small window. It also had the old-style window crank in the overhead for pitch trim. To this day, I can’t tell you which direction is nose-down, clockwise or counterclockwise.
