US federal aviation regulations

Cited answers on 14 CFR Part 135

Ask in plain English. Every answer quotes the regulation it came from, with the section number, so you can check it against the source yourself.

Two kinds of question

  • Compliance “How much rest is required before a pilot can be assigned flight time?”
  • Compliance “Do the flight-time limits apply to a two-pilot unscheduled operation?”
  • Manual currency “Which parts of my General Operations Manual are out of date?”

Anything outside those two is politely declined — this is a narrow tool on purpose. More about how it works.

What we record while FC135.ai is in testing

  • Your email address
  • Every question you ask
  • Every answer we return, with its citations and cost

Administrators can read all of it. Attach a manual and we also record its file name and the text of its title page; the manual itself is deleted when you sign out.

You can erase your account whenever you like. That is permanent and ends your access — we keep only your email address, so the closure holds, and your usage total, which is a billing record. Operational logs are kept for troubleshooting. Full privacy notice.
