as ‘Out of working area’ or ‘High wind’³³.
Note: The most important status and warning messages are repro-
duced in the Status Panel in the Map Area, and thus remain visible
even when the Sidebar is hidden.
• Autonomy: The battery level displays the current charge and voltage of
the battery. As the battery’s charge level decreases, the voltage decreases
as well. A fully charged battery has a voltage of 12.6 V and is fully dis-
charged when it reaches about 9 V³⁴.
This section also displays the total time in flight, the straight-line distance
to the Home waypoint, the estimated time required to return to the Home
waypoint (based on estimated wind strength) and the quality of the radio
data link between the ground modem and the drone. The strength and
direction of the wind estimated by the drone is displayed with an arrow.
Caution: Lithium polymer batteries are chemical devices whose per-
formance depends on a number of parameters, including tempera-
ture, lifetime, number of cycles, mechanical integrity, etc. Estimating
the remaining capacity of a battery can thus be tricky and the dis-
played value may occasionally be inaccurate. It is the operator’s re-
sponsibility to monitor battery voltage and flight time in addition to
the battery level to make sure that endurance is sufficient to com-
plete the mission.
• Flight data: This section includes additional information that may be use-
ful during the flight, including ground speed and height, altitude Above
Mean Sea Level (AMSL) and the absolute position detected by the GPS on-
board the eBee.
