PilotGuard brings the FAA's Flight Risk Assessment Tool (FRAT) and PAVE framework to your iPhone and iPad — so every flight starts with a clear, structured go/no-go decision. HOW IT WORKS Enter your departure and arrival airports plus your estimated time of departure. PilotGuard instantly fetches live METAR and TAF data from NOAA and pre-fills your weather questions automatically. Answer the remaining questions across the four PAVE categories — Pilot, Aircraft, enVironment, and External Pressures — and get a risk score in seconds. LIVE WEATHER, BUILT IN No manual lookups. PilotGuard pulls real-time METAR and TAF for both your departure and arrival airports and maps the conditions directly to your assessment. Departure weather, en-route forecast, winds, and time of flight are all pre-filled based on what's actually happening outside. PERSONAL MINIMUMS Set your own limits — maximum crosswind, headwind, and tailwind, minimum runway length, VFR ceiling and visibility, and fuel reserves. PilotGuard checks every flight against your minimums and flags violations clearly in your results, so you're always flying within your personal envelope. RUNWAY ANALYSIS Select your departure and arrival runways and PilotGuard calculates the exact crosswind and tailwind components based on current winds — not just total wind speed. Includes density altitude so you know what your aircraft is actually performing against. FAA-SOURCED RISK MITIGATIONS When any PAVE category scores Moderate or High, PilotGuard surfaces FAA-sourced antidotes specific to that risk area — practical mitigations, not generic advice. FLIGHT HISTORY Every completed assessment is saved to your history. Review past flights, see how conditions compared to your minimums, and track your risk trends over time. BUILT FOR GENERAL AVIATION PILOTS PilotGuard is designed for student pilots building decision-making habits and experienced pilots who want a structured pre-flight discipline. It follows the same 18-question FRAT methodology recommended by the FAA, organized across the four PAVE categories. No account required. No subscription. Your data stays on your device.
