Methodology

• We connect to different ADSB aggregators for flight data
• We continually expand ADSB coverage by adding more aggregators
• Some aggregators provide origin and destination airports for us
• When origin and destination aren't available we locate the nearest airport to the first spotting for origin, last spotting for destination
• We collect aircraft registration data from FAA, Transport Canada, France's DGAC, and ADSB Exchange
• We rely on high quality airport location data available publicly
• We provide "kg CO2e emissions saved" calculation for fixed wing aircraft comparable to C172, and multiply flight duration x 88kg. When our duration figures are incorrect they tend to be smaller than actual, not larger, so this is a useful minimum, actual is likely higher.
• We don't yet attempt to provide calcs for EVTol, partially because most EVTol flight today is mostly certification work
• However, once they do begin flying non - certifications we are considering comparing against the Bell 407
• Charger locations are accurate as per January 31, 2025, but we do not have an ability to update charger status automatically - please do not use this as a charger planning tool
• For route planning we calculate headwind and tailwind from public weather data services. Current conditions at airports come from NOAA's Aviation Weather Center (METAR and TAF). Forecast winds aloft come from Open-Meteo, whose data is made available under the Creative Commons Attribution 4.0 licence (CC BY 4.0). We use winds at your selected cruising altitude rather than surface wind, because wind a few thousand feet up is typically several times stronger than at ground level and from a noticeably different direction — planning on surface wind would overstate how far you can fly into a headwind.
• Our database contains information from ADSB.lol (among other ADSB networks), which is made available here under the Open Database License (ODbL).
