SurfaceOps by uAvionix
Read full descriptionHide 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, andβwith your permissionβyour 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.

Verdict
The clearest difference is in-app purchases: SurfaceOps by uAvionix at none against Stellaris's 2. SurfaceOps by uAvionix also leads on device support (3 vs 1) and iOS requirement (15.0 vs 26.1). Stellaris's advantage is update cadence (every 4 days vs every 2 weeks). On price and ads there is nothing between them.
