I've got some hours in 152/172s...maybe 35 landings, but starting over since I can't find my logbook from 12 years back.
My new flight school only has Pipers for training. Any advice for someone going from a Cessna mindset to a Cherokee? I'm nervous about ground visibility for some reason.
I started in a Cessna, trained for 10 hours, and then took a forced three month break before starting training again in a Piper. I was a bit nervous about ground viz, too, before I flew the Archer, but either I just adjusted really fast or I realized I could still see plenty of the ground beneath me over the nose. I could see a lot more ground out of the front windscreen than I could in the Skyhawk, and after the first flight, ground viz wasn't even a worry.
As for landings, if you maintained good speed control on final, you could put that Hershey-bar wing Archer down exactly where you wanted it. As my CFI joked, "It has the glide profile of a brick!", and once you chopped power, it was coming down. Really good control of speed allows you to pick a soft or firm touchdown. It took me several hours to get used to the different sight picture, but once I got the seat positioning right, landings were a piece of cake, and actually were really fun because of the precision. Flying the traffic pattern was pretty much the same, but instead of looking out the side window, you look back over your shoulder. I can't say I picked any one spot on the wing to "set" the runway at during downwind, but it was pretty much 1/2 to one wing's length away. You turn base when the runway is about 45* off when you look over your shoulder. I think the traffic pattern is easier in a low wing, because you can actually see the runway when you're turning and can get a sense if you're in the right spot or not.
Maybe it was just because I had more time to get used to the airplane, but I felt like it was easier to maintain precise control of the Archer, and to make it do exactly what I wanted it to do. My recommendation is to give yourself lots of grace and make sure your CFI knows you started training in a high wing. I doubt it will make much difference since it was 12 years ago, but it just gives the instructor one more clue when they're helping you learn how to fly and land.
