Try the lookahead →Every duty period, every rest gap, every on-call window — encoded against the actual chief counsel interpretations, not just the FAR text. When the engine says LEGAL, you have the citations to back it.
See the engine →DOs and chief pilots get the full fleet/schedule/compliance view on the web. Pilots get the mobile app for duty logging and lookahead. Same data, two surfaces, one bill per operator certificate.
View pricing →We started Blocktime after one too many midnight calls asking the chief pilot whether the next morning's trip was legal. The math isn't hard — but the interpretations are, the rolling windows are tedious, and the spreadsheets break.
Blocktime encodes the math. We encode the interpretations the FAA actually enforces — Converse, Whitlow, Dewitt, Masterson — so the answer comes with the citation you'd want in front of a POI.
