Smart Flight Features

Go Home

The Go Home function can be enabled when good GPS signal is available. To manually activate the Go Home process, press and hold the Go Home Button  for 3 seconds on the remote controller to send the Go Home command to the aircraft. Once the aircraft receives this command, it will return automatically and land at the present home point.

According to the new design, the aircraft is able to detect and avoid obstacles on its flight path using Forward Vision System. Normally the remote controller’s function will be disabled temporarily while the aircraft returns to the home point, but you can still regain control of the aircraft by pressing the Pause Button  on the remote controller if the Forward Vision System is disabled during this period.


IMPORTANT

  • When the Go Home function is activated, for safety reasons, if the aircraft is hovering at the altitude lower than 30 meters, it will ascend to an altitude of 30 meters above the home point before starting to return. You can adjust the Go Home altitude in the app.
  • If the Go Home function is activated within 10 meters radius from the home point, the aircraft will land automatically in-place from its current altitude.

    Failsafe

    The Failsafe function is designed to help EVO automatically return home or land onsite when necessary.

    Communication Lost

    Failsafe will be triggered 3 seconds after the communication between your aircraft and remote controller gets lost.

    If GPS is available when activating the Failsafe function, the aircraft will start the Go Home procedure automatically, otherwise it will land onsite. When the remote controller signal comes back, you can still press the Pause Button  to regain control of the aircraft.

    Low Aircraft Battery Level

    Failsafe will also be activated if you meet one of the following low battery conditions.

    A. Your aircraft battery constantly calculates the required battery level for the aircraft to return to the home point from its current location. When the battery level reaches the minimum level required for the aircraft to return to the home point, a notice displayed on the Autel Explorer™ app will prompt you, Failsafe will be activated and your aircraft will automatically return home to protect itself. You can regain control of the aircraft by pressing the Pause Button  during the Go Home process.

    B. Anytime your aircraft’s remaining battery level reaches 25% (Low Battery Warning), Failsafe will be activated and your aircraft will automatically return home. If you regain control during this process, the aircraft will automatically land onsite when the remaining battery reaches 15% (Critically Low Battery Warning). In this case, you may press the Pause Button  to stop the aircraft landing and command it to fly away from the current location for a safe landing in case of an emergency.


     NOTE

    • If the aircraft is only within 50m away (horizontal distance) from the home point when your aircraft battery level reaches 25% (Low Battery Warning), the aircraft will not perform the Go Home procedure.
    • If GPS is unavailable when Failsafe is activated at Low Battery Warning, Go Home procedure will not be executed. In this case, the aircraft will land automatically when the remaining battery level reaches 15% (Critically Low Battery Warning).

    Landing Features

    Landing Protection

    When the aircraft arrives at the above of the home point, Landing Protection functionality will detect ground conditions during the landing descent. The aircraft will land automatically if the ground is level and flat, otherwise it will hover in-place to wait the next command.

    Accurate Landing

    EVO will scan and match the terrain features if Accurate Landing function is active, it will land as close as possible to the take-off point once the current terrain matches take-off point terrain.


     IMPORTANT

    • The aircraft records the take-off point as the default home point, Accurate Landing is only working when the home point is not refreshed during the flight.
    • Make sure there are no changes of your take-off point when the aircraft is ready to land.
    • Choose a distinctive terrain as your take-off point. • Choose a spot on the ground that is well lit to take off and land your aircraft.


     NOTE

    • Landing Protection and Accurate Landing can be enabled via Autel Explorer™ app, the instructions are available in the App Manual.

    Starpoint™ Positioning System

    The Starpoint™ Positioning System installed on EVO, functions through Binocular Cameras and two Ultrasonic Sensors on the bottom of the aircraft. The sensors identify the current height of the aircraft through ultrasound, and the camera obtains location information through image analysis. With the help of the Starpoint™ Positioning System, the aircraft can hover in place more precisely when flying indoors or in other environments where the GPS signal is unavailable.


     NOTE

    • The StarpointTM Positioning System is activated by default when the aircraft is powered on.
    • The StarpointTM Positioning System works both in GPS and ATTI modes and is only valid when the aircraft is between 0.5m and 10m above the surface.

    Forward Vision System and Rear Avoidance Sensors

    The Forward Vision System installed on the front of the aircraft using image data to detect the distance between the aircraft and obstacles. The aircraft will brake by itself when obstacles are detected in front.

    At the same time, infrared sensors located on the rear of the aircraft are also capable of measuring the heat being emitted by an object and detecting motion, which will help the aircraft avoid obstacles in a different way.


     TIPS 

    • Always keep the binocular camera lens clean for a clear view.
    • Do not use other 40KHz ultrasonic devices nearby when the StarpointTM Positioning System is activated.

     IMPORTANT

    The performance of the Starpoint™ Positioning System and Forward Vision System are affected by the brightness and texture of the surface over which the aircraft is flying. The ultrasonic sensors may not function accurately above sound-absorbing materials. Please try to avoid the following situations:

    • Flying over a monochrome surface (e.g. pure black, white, or red) or a highly reflective surface (e.g. water, transparent surfaces).
    • Flying over extremely dark or bright surfaces, or in an area where the lighting changes frequently.
    • Flying over surfaces with unclear patterns or texture, or highly repeating patterns or texture (e.g. tiles with the same design).
    • Flying over surfaces (e.g. thick carpet) that can absorb or deflect sound waves.
    • Flying at a high speed: Over 8m/s at a 2-meter height, or over 4m/s at a 1-meter height.
    • Flying over moving surfaces or objects
