IMPORTANT
This app is an educational reference and planning aid. It is not a scheduling system, a legal opinion, or a replacement for your certificate holder's policies, AIMS/company operations, or the Federal Aviation Regulations. Table C values are representative (commonly cited Class 1 rest-facility values); §117.17 has per-class variants. The pilot in command remains responsible for all duty, rest, and flight-time compliance. Always verify against current company guidance and the FAR.
