At what speed to you fly the downwind leg in a 172? I just had a solo evaluation flight. I'm on instructor #3 (no drama, they just keep leaving ). He was horrified at me flying the downwind leg of the pattern at 100 kias. I was sure that instructor #2 recommended this. I remembered him saying that if you go too slowly you'll have other traffic catching up. I could have taken it up wrong though, so I had a look at some older videos, and found one where instructor #1 definitely told me to shoot for 95. Anyway, instructor #3 says if I do 100 on downwind in the checkride I'll fail. He says 80 is what I should be going for. This kind of threw me off because I had to get used to trimming differently (up on downwind, then down later). Whereas the way I was shown before, I just trimmed down a little on downwind and then I didn't have to touch it again. No big deal, I trust instructor #3 completely and I've gotten used to it now, but I just wondered what speed other people fly downwind at in a similar aircraft?
