The new flight screen (lib/ui/fly/fly_screen.dart) is built from layers.
Each readout listens to its own telemetry sub-model, so a 10 Hz tick only
repaints what changed. It adds a status bar with a status chip and tip
marquee, a smart battery bar with land/RTH markers, a camera info strip,
an attitude ball, an H/D/VS/HS/VPS strip, and a minimap that swaps places
with the video when tapped. The HUD is laid out in design pixels and
scaled to phone or tablet inside the safe area.
What the HUD shows depends on the product: dual or multi battery bars,
SSD status, a thermal spot reading, a master/slave RC badge, and Wi-Fi
bars in place of RC/HD. The bridges now report the data for these: the
camera's ssd/thermal groups and the RC's master/slave mode.
The old FlightControlPage can still be opened from Settings > About >
Classic flight screen until the P3 safety flows land. The same tab also
gets a toggle for the performance overlay.

The GO 4-style HUD needs far more live data than the bridge sent, and
pushing every SDK callback straight to Dart would rebuild the screen
dozens of times a second. This is the telemetry foundation (plan P1).
On the Kotlin side, every source now writes into a TelemetryHub that
emits one telemetry event per tick: flight-controller state, gimbal and
vision at up to 10 Hz, battery, links, RC, storage and camera settings
folded in at up to 2 Hz. Each event carries the full latest snapshot, so
a consumer that drops packets never loses a slow group. New bridges
cover batteries (every pack, cell voltages, warning thresholds), link
quality and RC battery, diagnostics, and obstacle sensing per sensor.
KeyBridge adds generic getKey/setKey/listenKey over KeyManager for the
settings rows to come. The flight controller also gains smart-RTH
confirmation and simulator start/stop.
On the Dart side, FlightModel now owns one ChangeNotifier per subsystem
(aircraft, battery, links, camera, gimbal, vision, alerts, mission), so
a HUD widget can listen to just the one it draws. TelemetryReducer
routes events into them, only notifies groups that changed, and gives
FlightModel one notification per tick. Flat getters keep the existing
screens working. Diagnostics become graded, de-duplicated alerts.
Settings > About > Telemetry inspector shows every field live and can
start the simulator.
Battery no longer arrives as its own event, so the API Server reads the
percentage from the telemetry snapshot (the old event is still accepted).
