Brian Glidewell and Lev Popov, two students in 6.171 last semester, have open-sourced the system that they wrote for East Coast Aero Club. Their system is an online community and online scheduler for a group of about 500 pilots and 30 aircraft. Details on how to download are available at http://www.eastcoastaeroclub.com.
It was almost unusable right after launch, an illustration of the unavoidable hazards of software development. In response to user feedback, Brian and Lev changed less than one percent of the code and now it seems to do most of the things that we need. The whole thing is Ruby on Rails/PostgreSQL and should be easy for other flight schools to adopt.
I tried to get a look at the system in operation on the East Coast Aero site, but couldn’t find any way to see the schedule. I was curious about it because my employer also has a custom web-based FBO scheduling application:
