Operating over a localized Bluetooth Low Energy (BLE) mesh network, it keeps events flying smoothly by securely syncing flight-line queues, schedule updates, and real-time "On Deck" pilot alerts completely independent of cell service or Wi-Fi. Built for both pilots and race directors, the app features smart local notification syncing, an interactive gesture-driven safety onboarding flow, and a pro-grade RF deconfliction tool that runs advanced V-pattern heat algorithms to instantly eliminate signal interference across mixed Analog, HDZero, Walksnail, and DJI video systems.
