Engine Run Ups
Everyone knows when flying piston aircraft that run up checks are important, and back at flight school I was always taught it's something you do in between engine start and takeoff (of course!). But I've seen a few places doing runups first thing in the morning, then taxiing back and shutting down, getting passengers, starting up and going straight to the runway. Subsequent flights later in the day have no runups immediately before.
Am I the only person who sees this as being a bit strange? During that next shutdown or start sequence couldn't a problem arise and subsequently go unchecked, especially in outback Australia where aircraft engines get quite a battering with heat?
Cheers!
