I'm going to disagree a little with FHHuber about getting your own gear to start your engine.

It may depend on where you are and who you're flying with of course. But around here, on most days, I have multiple students I'm cycling though. If everyone was constantly moving their planes around the pits to get to my field box, it would be a royal pain. Not only that, my glow starter and such would be dead in short order. Things work a lot smoother when I can just walk from one pit to the next. On busy days in the past, my club has even had people doing "ground support" basically helping the beginners with engine starting and getting in to position and such, so the flight instuctors just fly.

With my students who are farther along (but who can handle an engine safely, etc), but not soloed yet, I'll frequently tell them "ok, you're next in line. When you see us land and taxi back, give me a few moments for debrief, then start your engine and get in to position, I'll join you on the flight line".

Now, if you have a club that has a 1-to-1 instrutor-student ratio, then this is not necessary. On the other hand, we have many more students than we do instructors, so I like to get guys as much air time as possible.
