7.13 Flight Fly View

When the RPA has to be flown, you need to go to fly view. This is the area from where the flights are managed and tracked. The flight fly view has various options displayed on the left drawer as below.

Once clicked on Take-Off, the ARM and takeoff commands are sent to RPA. RPA will do the basic pre-flight check and do the takeoff if everything is proper.

The land button enables you to make the RPA land. Once it is clicked, the RPA will stop by slowing down the flying and start coming back to the point given to the land. This button will be enabled only if a flight has already taken off. If the take-off command is not given then this button will remain in disabled mode.

Return to Land (RTL) is used for an emergency landing at home. The device will find the shortest distance to land at home. If the rally points are added to the plan, then the device will check the minimum distance between either the home or rally point for landing. The device will select a minimum distance for a safe landing.

The pause command will give pause instructions to the RPA. Under this condition, the RPA will pause at the point it is flying. It will go into 'hovering' mode at the given location. Once the pause is active then the RPA will enable resume action.

The resume command will give operation resume instructions to the RPA. Under this condition, the RPA will resume the flight from the point where it was paused.

6) Live Details

Few parameters of the performance of RPA has shown on the Flyview screen. The important one is the heading position of the RPA. Using the magnetometer, the AeroGCS will show the live heading position of the heading of RPA. Similarly, the AeroGCS will show the value of the battery available. Based on the status of the remaining power of the battery, the AeroGCS will showcase the usage and remaining power in the battery.

AeroGCS shows the position of the drone using navigation parameters like longitude and latitude. These readings are taken from navigation equipment like GPS. Altitude is also shown as the positioning parameter of RPA. The altitude value is driven by the barometer of the flight controller hardware.

The AeroGCS shows nearly real-time values of the Inertial Measurement Unit (IMU) to show the self-position of RPA.

The speed of the drone and wind speed are also displayed continuously on the flyview.

The status of the battery is displayed as the voltage and current.

Vibrations on the drone are displayed with X, Y, and Z coordinate values.

HDOP: The term "horizontal dilution of precision" (HDOP) is used to describe the strength of the geometry, or satellite configuration, in use at the time and its effect on the accuracy of the data collected by a GNSS receiver. It is used to determine the relative accuracy of horizontal position. HDOP is a measure of accuracy in a 2-D position (e.g., latitude and longitude), whereas VDOP is a measure of accuracy in a 1-D position (height). Typically, HDOP values range between 1 and 2.

RSSI: RSSI stands for Received Signal Strength Indicator, and it essentially measures the quality of communication between a radio transmitter and receiver pair. When converted from PWM, the RSSI value normally has a range of 3.7V to 0V (100% to 0%). Even if it is not a percentage but a voltage that is displayed, you can still get a good idea of what the RSSI level is.

7) Live Tracking

The AeroGCS continuously tracks the live position of the RPA. It gets the latest coordinates of RPA position and then AeroGCS shows the current position of the RPA on the mission plan. Whatever distance the RPA has covered, it will show the distance covered with heading direction of the RPA. If there is a latency between the AeroGCS and RPA then AeroGCS will show the position with latency.

AeroGCS KEA 2.3 version added a few more features on the fly view window as shown in the following image.

  • Name of Project and Plan: It shows the name of project and plan associated with the flight on the top left-hand corner

  • Distance measured: It shows the distance measured during the flight

    • between the home position and waypoint

    • between the two waypoints also

  • Status text messages on flyview: It shows detailed instructions, status and actions performed during flight such as "Arming Motors", "Disarming Motors", "Mission 11 WP", etc. as shown in the above image.

  • Mode change on flyview through list: The drone can be operated in various modes as discussed in section 6.6 of the same manual. These modes can be changed during the flight by just clicking on the modes options and arrow present as shown in the following image. The selected mode will be applicable to the flight. It will reflect the actions performed during the flight.

Select the proper flight mode to make the flight safe and secure. The "Mode Change" functionality is applicable to any flight type.
