Interface Overview

  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

1. Speed & Altitude Tapes

The tapes are dynamic vertical scales.

  • 13: Ground Speed (GS): Displayed numerically above the speed tape.
  • 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

  • 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.

Privacy Policy for MAVLinkPFD

Last Updated: March 17, 2026

1. Overview

MAVLinkPFD (the “App”) is designed to function as a Primary Flight Display using the MAVLink protocol. We value your privacy and believe that your flight data belongs to you. This policy explains our stance on data collection and privacy.

2. Information Collection and Use

MAVLinkPFD does not collect, store, or transmit any personal information or flight data.

  • No Personal Data: We do not collect names, email addresses, or contact information.
  • No Flight Tracking: The App processes MAVLink data packets locally on your device to display flight telemetry. This data is never recorded by the App or sent to the App author or any third party.
  • No Location Tracking: While the App may display GPS coordinates provided by your flight controller, it does not track or store your location history.
  • No External Transmission: The App does not communicate with any external servers. All data processing happens entirely “on the edge” (locally on your device).

3. Permissions

The App may request certain permissions (such as Bluetooth or Network access) solely to facilitate the connection to your MAVLink-enabled hardware (e.g., telemetry radios or flight controllers). These permissions are used strictly for real-time display purposes.

4. Third-Party Services

The App does not use third-party analytics, advertising networks, or tracking SDKs (Software Development Kits). There are no “hidden” cookies or trackers.

5. Data Security

Because we do not collect or store any data, there is no risk of your personal information being compromised from our systems. Your flight data stays within your local hardware environment.

6. Changes to This Policy

We may update this Privacy Policy from time to time. Any changes will be reflected by the “Last Updated” date at the top of this page.
