SurfaceOps by uAvionix vs ZoneGlider

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.

Timezone math sucks. You know how it goes. Someone says "4pm my time", and now you're counting on your fingers, opening a converter in another tab, and getting it wrong by an hour anyway because one of you moved the clocks last weekend. ZoneGlider puts your cities where they actually are on the planet, and lets you drag the daylight across them. Move it forward and 4pm Wednesday in Brisbane becomes 11pm Tuesday in Los Angeles, so you read the answer off the screen instead of working it out. DRAGGING TIME AROUND Drag anywhere on the screen. A screen width is twelve hours. Push it gently and it creeps along; throw it and it covers days, because the gearing follows your hand rather than the other way round. WHO'S AWAKE, WITHOUT GUESSING Every city gets a 24-hour track on one shared axis, so the rows line up instead of each telling its own private story. Flip to the Availability lens and those tracks turn into flat bands: awake, and asleep. You set your hours and theirs. "Can I call them right now" becomes a colour instead of a calculation, which is the entire point.
