Emergency Low Battery

Emergency Low Battery is defined as total battery percentage under 5% and means the UAS is in danger of not having enough remaining endurance to safely land in place (Land).

Automated Failsafe: From the factory your IF800 Tomcat has an Emergency Low Battery failsafe enabled that will automatically initiate an auto Land in Place flight mode at 5% battery, regardless if the aircraft was in a manual or automated flight mode prior to this. The Pilot can switch the flight mode out of Landing mode after the failsafe was initiated, however the aircraft will not automatically enter this failsafe again. If in doubt, manually land the aircraft as quickly as possible.

When the aircraft is in RTL, the pilot can manually adjust horizontal position while the aircraft automatically lowers its altitude.

Flying with Emergency Low Battery level: The Pilot in Command’s main objective needs to be safely landing the aircraft as quickly as possible to prevent loss of control. Use the onboard cameras to find the nearest clear open space and land immediately. Recovering your aircraft from an inconvenient location is always better than recovering a crashed aircraft.

Automated flight modes may use slower velocity setpoints than the aircrafts max speed. If in doubt, switch to manual Position Hold flight mode to land faster.
