Catch a bad crosswind or leg-time assumption before engine start. E6B Pilot Flight Computer helps student pilots, CFIs, and other manual-planning pilots turn runway wind checks, wind previews, and nav-log cards into a faster preflight and teaching workflow without opening a full EFB. Use the free core to: - check runway crosswind plus headwind or tailwind components from manual wind and runway inputs - check density altitude from pressure altitude and outside air temperature before opening aircraft performance tables - preview wind correction angle, heading, and groundspeed from true course, true airspeed, wind-from direction, and wind speed - keep the workflow fully offline with no account, ads, or live EFB scope Unlock Nav-Log Cards to: - turn a wind leg into a full nav-log card with heading, groundspeed, leg time, and fuel required before reserves - save, pin, and reload local training or preflight cards on iPhone or iPad - share a plain-language training summary for debrief, lesson handoff, or planning notes - unlock the full student-pilot and CFI drill-card library for repeat runway, wind, and leg-time practice Why pilots keep it: - catch a runway-component or leg-time mistake before engine start - practice manual E6B thinking without rebuilding the same math in notes, spreadsheets, or browser calculators - hand off a clean training or debrief card instead of rewriting numbers - stay focused on one review-safe manual planning job instead of a broad aviation suite Important: Results are planning and training references only. Always verify runway choice, performance, fuel reserves, and operational decisions with your POH or AFM, current conditions, and pilot judgment. This app is not FAA-approved avionics and does not provide navigation, live weather, charts, flight-plan filing, or aircraft integration.
