A few days ago I watched an FO preflight a CRJ-700. Today I sat across from an RP (student) and watched him preflight a Hornet. I think it took the RP longer!

So this got me to thinking.......how long does it take you to preflight your type of aircraft (C-152 to 747-400)? Does the time change appreciably depending on different conditions - day/night, weather, first flight of the day, etc...? Please - share your experience.
