Features
Read full description

Surface Ops is a free situational-awareness tool for anyone interested in airport surface operations β€” pilots, students, ramp staff, plane spotters, and the general public β€” with optional licensed features for professional airport ground-operations teams. Free for everyone, at every US airport: β€’ Airport diagrams (runways, taxiways, aprons, hotspots) β€’ GPS-based ownship position on the airport surface β€’ METAR, TAF, and D-ATIS weather β€’ Live ADS-B traffic from a uAvionix skyAlert receiver (a separately-purchased consumer accessory) β€’ Runway-incursion alerts: CHECK RUNWAY, TRAFFIC RUNWAY, CHECK FINAL, TRAFFIC FINAL and Aircraft Emergency Alerts β€’ Visual highlighting of the runway under alert β€’ Offline operation once an airport diagram is cached (weather requires internet) Optional licensed feature, at participating airports: Airports that contract with uAvionix for the professional toolset can issue a one-time activation code to their authorized vehicle operators, which adds the FlightLine ADS-B network traffic feed from the airport's ground-based receivers, no per-vehicle hardware required. No in-app purchase. The app and all consumer-facing features are free. Licensed airports pay uAvionix directly; the end-user operator never pays anything inside the app. What Surface Ops is NOT: β€’ Not a certified safety system β€’ Not a substitute for ATC instructions or established ground-movement procedures β€’ Not a primary means of collision avoidance β€” visual scanning and radio communication remain primary Privacy Surface Ops collects only what's needed to operate: your activation code, a per-device licensing identifier, andβ€”with your permissionβ€”your GPS location to display your position on the airport map. Location data stays on the device; we do not transmit it to our servers. No analytics, no advertising SDKs, no tracking.
