Simple FDP & Off-Block Planner

$3.99 · Designed for iPad. Not verified for macOS.

Calculate FDP, plan off-block times, and tailor duty settings in one clear place. Plan flight duty with clear times and controls. Simple FTL Calculator helps flight crew and operations teams estimate maximum flight duty periods (FDP) and plan target off-block times. • Calculate an FDP end time from report time, crew type, and sectors. • See split-duty break duration and extension. • Work back from an FDP end time to a target off-block time. • Adjust duty timing and use custom FDP tables for your operation. • Save inputs and results for the next time you open the app. • Use light or dark mode, even offline. Built-in tables and custom settings are planning aids. Check each result against your operator’s approved procedures and the rules that apply to your flight. Questions or suggestions?

Saved FDP and Target Off Block results now restore more reliably. Settings changes prompt recalculation, Target inputs receive clearer validation, and custom FDP table edits check time bands and values. This update also improves compatibility with current iOS and iPadOS versions.
