Time log

This windows shows current uptime as

registered by the autopilot. This is the time that

has passed since the power-on of the autopilot.

This time is always positive and it is

monotonically increasing. This time counter only

resets at autopilot power-on, so it is an

appropriate way to detect power supply

problems should they arise.

Take-Off time shows how much time has passed since the last U-See detected

automatic take-off phase.

This means that this time won't be accurate if:

• The flight is started in manual or semi-manual modes.

• The take-off occurred while the current U-See instance was not running.

• Control handover has occurred and a different UAV is being monitored.

Pre-Flight Menu

The tools on Pre-Flight drop down menu have to be used before the flight starts, with the

UAV on the Runway, with communication with the U-Ground and with GPS signal.

Safety Warning

It is very recommended to set the manual mode and keep the throttle on

the joystick to minimum while adjusting the pre-flight parameters to

minimize injury risk to persons around the UAV in case the operator makes

a mistake.

It is also very recommendable to keep engines or motors turned off until the UAV is

ready for flight.
