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
• Our database contains information from ADSB.lol (among other ADSB networks), which is made available here under the Open Database License (ODbL).
