SurfaceOps by uAvionix vs MachCrit Pilot Logbook

Surface Ops is a free situational-awareness tool for anyone interested in airport surface operations — pilots, students, ramp staff, plane spotters, and the general public — with optional licensed features for professional airport ground-operations teams. Free for everyone, at every US airport: • Airport diagrams (runways, taxiways, aprons, hotspots) • GPS-based ownship position on the airport surface • METAR, TAF, and D-ATIS weather • Live ADS-B traffic from a uAvionix skyAlert receiver (a separately-purchased consumer accessory) • Runway-incursion alerts: CHECK RUNWAY, TRAFFIC RUNWAY, CHECK FINAL, TRAFFIC FINAL and Aircraft Emergency Alerts • Visual highlighting of the runway under alert • 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: • Not a certified safety system • Not a substitute for ATC instructions or established ground-movement procedures • Not a primary means of collision avoidance — 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, and—with your permission—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.
