Ryan, Grant says to include a landing gear check in your checklist, "if you intend to continue professionally" . Why wait until someone is paying you to fly in order to learn a landing checklist the correct way? Many of the exciting airplanes in the world have retractible gear, ( certainly not all like Cub or Sukio). so why not learn to incorporate this in your thinking from the start?
I try to think of landing gear down as the main point of my checklist no matter if I am flying a fixed gear glider or a turbo Bonanza.
Having the gear down for landing is the essence of the landing procedure. There may be other things on the factory POH or checklist that are written before gear down, like some fast planes use partial flaps to slow to gear speed. However, all these other things like fuel pump on or even flaps down are nice to have, but THE ONLY ESSENTIAL ITEM IS GEAR DOWN (and confirmed down).
So as you descend for landing or as you enter the pattern for landing, think about lowering the gear above any other item.
I have twice had landing gear fail to lower and had to crank it down by hand, and once could not get a green light due to a broken wire even though the gear was safely down. 3 different planes over about 30 years.
You can walk through a landing pattern on the ground, you can use a sidewalk or a driveway as a pretend runway and think of what you'd do, and what you'd check at each part. . By the way , radio calls may be good, but planes fly just fine without even having or using radios. Don't drop the airplane in order to pick up the microphone. The gliders I fly don't have radios. Some very busy airports may have a lot of jet ifr traffic and they aren't good at looking out the window, but some other places may be very basic.
