  1. Flight Mode & Status: Located top-left. Displays current state (e.g., AUTO). Displays also the state of Safety or Arming.
  2. Speed Tape: Shows Indicated Airspeed (IAS). Long boxed areas represent stall speeds; checkered areas indicate overspeed limits. Units are selectable.
  3. Altitude Tape: Displays current altitude. Units can be m/s or feet.
  4. Artificial Horizon (AHI): Central attitude indicator. Features a pitch ladder (horizontal lines) and a fixed aircraft symbol to show relative pitch and roll.
  5. Bank / Roll Scale: Displays the current roll angle. The moving triangle (pointer) indicates degrees of bank.
  6. Slip/Skid Indicator: Small bar below the bank pointer.
  7. Heading Indicator: A compass rose showing degrees (e.g., 165).
  8. Battery & Power Status: Top-right. Shows Voltage (V), Power (W), and Throttle percentage. Blinks during low-voltage, faster during critical voltage.
  9. GPS / RTK Status: Bottom-left. Displays fix type (e.g., RTKFLT) and satellite count (e.g., 18), flashes in case of GNSS loss.
  10. Wind Indicator: Shows wind speed and an arrow representing direction relative to the current heading.
  11. Rangefinder Altitude: Displays precise distance to ground if a Radar,LiDAR or sonar sensor is active.
  12. Home Indicator: Indicates distance and bearing back to the launch/home point.

Detailed Feature Descriptions

  • Target Bugs: Visual markers on the tape indicate set cruise speeds or target altitudes.

2. Navigation Display (Active Flight Plan)

When a navigation is active, the following elements appear:

  • 14: Flight Director (FD): Crosshair or bar symbols on the AHI guiding the pilot to the target path.
  • Waypoint Info: Bearing and distance to the next waypoint are displayed as overlays.

3. Connection & Safety Alerts

  • MAVLink Status: If the data link is interrupted, a prominent “MAVLink lost” warning appears in the lower right with a disconnection timer.
  • App Status: Similar warning for the mobile/tablet application connection.

4. Hardware Monitoring

  • 15: Device Battery: The UI includes icons for the battery level of both the Rokid Glasses and the connected telemetry phone/tablet.
