Flying Multi-Battery Missions

Creating Big Maps Using Multiple Batteries

The best part of Map Pilot is its ability to help mappers estimate and optimize the flight path required to map a given area. Even when this area will require more than one battery to complete, Map Pilot will estimate the number of batteries required and keep track of where each battery leaves off.

Changing Batteries

After the aircraft lands, power it down normally, swap the battery and power it back up normally. As soon as the camera preview window has live video in it again, the aircraft is ready to manually takeoff and upload the remainder of the flight.

 

Mission Estimates

When planning a mission, the requirement for multiple batteries is denoted in the Flight Plan Statistics pullout (top left) and also on the map shown by the alternating white and grey flight paths. The image below shows a flight plan which will require 4 batteries.

 

Mission Planning only takes the Battery Maximum Flight Duration setting into account. Battery Timer settings from 11 to 18 minutes will be reflected in the estimated flight duration and flight path estimations. Battery Limited operation simply reflects a battery duration of 24 minutes which is longer than any DJI aircraft can currently fly (aside from the Matrice with two batteries). Estimates for Battery Limited operation will be less accurate than the Battery Timer settings.

There are three things that can bring an aircraft home to swap out a battery:

  • Battery Timer Running Out
  • Battery Running Out of Power
  • Return to Home Buttons

Any time the aircraft lands, there will be a message that states the Flight N is complete where N is the count of total flights.

 

Battery Timers

A Battery Timer of 11 to 18 minutes will send the aircraft home when the aircraft has been in the air for the nominated amount of time. This can be useful for cases where you know that conditions will limit your battery duration and you want to have a really accurate count of required batteries.

The pilot will know more about the state of their batteries than Map Pilot will and can use Battery Timers to share this information with the app.

 

Return To Home Buttons

At any time during flight, the user can either push the "Go Home" button in the Flight Control pullout (top right) or the Return to Home button on the remote control. This will drop an Abandonment Point and the aircraft will return home.

Remember to set you Return to Home height appropriately in the DJI Go app.

 

Battery Power Triggered Return To Home

The smart batteries in the Phantom 3 and Inspire 1 drones know how much power it will take them to get home. When the aircraft realizes that it is further away than it has power to get home, it will immediately head for home and draw a Abandonment Point on the Map Pilot map.

We have tested this extensively and have had no problems with it. Remember that the aircraft's distance to home power requirement will likely be wrong in the case of a stiff headwind so keep that in mind. 

 

Abandonment Point 

Abandonment Points are the blue dots that get drawn any time the aircraft leaves its intended flight path to head for home. After going home and getting a new battery, it will proceed back to the blue point and continue on with the mission.

    What happen if we need to close everything including the app, drone,... for example in case of raining? How can we resume the flight mission?

    You can restart the partially finished mission as long as you haven't cleared it.

    This is huge! Wow, testing today.

    It is not possible to draw a bit more complete study shape. It always give much bigger study area.

    What do you do when it does not want to resume to the Abandonment Point (blue dot)?
