Facility scheduling app for an airline

I need to create a simple application to manage the scheduling of aircrafts and its crew. Is anyone aware of a similar project (hotel, tennis court or others) which could serve as a launch pad? Thank you, Olivier RoR developer and Airline Pilot

Open Campground is an app scheduling campground sites. You can take a look and download it at opencampground.com. It is rails 2.3.18 so some things have changed but the central issues are about the same.
