K4 Tools

Fuel, Rest, Duty & Flt Calcs

Free

K4 Tools helps flight crews complete inflight fuel and time checks quickly and accurately — with calculators built around your current flight plan. Highlights: • Magic Scanner: Use the iPhone camera on support models to scan the FMS Position Report and auto-fill required fields. • Duty/Rest Calculator: See Max Duty End, Latest Legal Takeoff, and required rest based on crew size, sequence, and consent — with live remaining duty. • Crew Rest: Share break schedules and keep track visually on the crew break Timeline. • Fuel Checks: Verify pre‑flight fuel upload accuracy across multiple receipts. • Pre-flight weather verification via calculated ETA's at Departure, Destination, Alternate, and ETP Airports. • iPhone + iPad: Optimized for both portrait and landscape use on iPad — including mounted flight-deck configurations.. Limits and warnings appear when operational or contractual thresholds are approached or likely to be exceeded, so you can take corrective action early. Planned updates: - B777 flight plan support for both standard and ETOPS plans. - Crew Rest Alarms automatically set for selected break period. - Custom Crew Rest break lengths
