How to Use
Identify Need for Battery Swap
The PHX can perform a battery swap whenever the user feels it is an appropriate time.
The recommended time for a battery swap is when the battery remaining is between 30% and 25%. This gives the PHX time to land and have enough power in reserve incase the landing needs to be aborted or adjusted.
Note the Waypoint
Best practice for multi-battery PHX flights is to maintain awareness of flight progress. Specifically, which waypoint or transect the drone is at when it departs from the flight plan to land for the battery swap. This allows the pilot to know where the drone should be returning to after the battery has been changed. This helps ensure that all the data for the field is collected and no images are missed.
Flight progress (red flight path lines) are not persistent. They will disappear once the aircraft is powered off. They will not reappear when the aircraft is powered back on.
Tip
If multi-battery missions are often being flown it may be useful to enable the mission item index telemetry value.
Use RTL
Use the RTL button on the left-hand side of the Fly screen to command the aircraft to land.
Use Post-Flight Menu
Once the aircraft has detected that it has landed it will automatically disarm. Once the aircraft disarms the post-flight menu will appear on the right hand side of the screen.
Use the menu to adjust the flight plan accordingly.
This menu will display three options for what to do with the flight plan:
Remove Plan From Vehicle
This will remove the current flight plan from the aircraft.
This is NOT recommended for a battery swap.
Leave Plan On Vehicle
This will leave the flight plan that is currently on the aircraft as it is currently planned.
Resume Mission from Waypoint X
This will update the flight plan that is currently on the aircraft so that it starts one waypoint before the last waypoint the aircraft was headed towards. It will also remove any of the previously completed waypoints and shorten the total flight plan size.
Remove Used Battery
Go to the aircrafts location and remove the discharged battery. Then recover the aircraft.
If the battery is removed before the post-flight menu is used it will not become available and the flight plan that was on the aircraft will persist.
