I was thinking about this flying around on Christmas day. The topic of touch and goes is pretty contentious amount us Mooniacs, and as I was flying around I was giving it some thought. I was just out to do some landings, so why not just stay at my home drone and do some T&G's? I decided that I really wanted to practice approach and landing, i.e. slowing the aircraft down and going through all the things I have to do to transition from cruise to landing. Gotta slow the airplane down, have to get the gear out, flaps out, cowl flaps open, boost pump on, mixture and prop adjusted, and landing light on. I'm probably forgetting something as I write this. Just doing T&Gs, I don't do any of that. Granted I was at low power, normally I have a lot more slowing down to do. But in this instance I found flying between nearby airports to be really good practice. And it was Christmas so I wasn't in a hurry.
I think T&Gs are a bad idea in a complex airplane. Too damn much stuff to do in too little time, you can easily forget something important, like the gear. It's happened. But lots of folks think otherwise.
