N
: The red error message does not disappear, even when the battery voltage is 10.2 V or
OTE
higher again.
1
In case of the yellow warning message, issue the LAND command.
Note: The yellow warning can also appear during turns but as long as the voltage
recovers to 10.2 V or higher, there is no need to issue the LAND command.
2
If the flight continues and the indicator turns red, issue the LAND or FTS command
depending on the location of your landing point.
3
If you did not issue any command and the battery voltage drops below 9.6 V, the motor is
automatically powered off. The throttle will go to 100% and the X100 will lose height. The
X100 will glide to the ground while following its flight path. If the situation is too critical,
issue the LAND or FTS command depending on the landing location.
23.1.7
Handle a low battery warning during flight (9.6 V)
If the battery voltage (MPBat) drops below 9.6 V in flight, the motor of the X100 is shut down.
The aircraft will glide to the ground while following its flight path.
23.1.8
Handle a communication link failure during flight
Scenario:
The communication link between the GCS and the X100 is disconnected. The LINK status bar
field in Horizon turns red.
N
: The downtime counter always takes in account the total communication downtime
OTE
during the flight. It also takes in account the uptime during the flight.
1
An automatic fail-safe mechanism is triggered when the communication time-out has
expired (Advanced Setting in Quickfield). The X100 autopilot will self-issue the HOME
command.
2
If the communication between the X100 and the GCS is restored before the take-off posi-
tion is reached, the aircraft resumes its flight. Keep an eye on the battery voltage, make
sure that it is enough to complete the flight.
3
If the communication between the X100 and the GCS is not restored before the take-off
position is reached, the aircraft lands following the landing circuit.
N
: When the communication link is down, the time-out counter will count down per second.
OTE
When the link is restored before the landing procedure is started, the time-out counter
increases again per second, with a maximum value equal to the value set in Quickfield.
Example for a communication time-out value of 60 s:
●
The communication link is lost for 50 s; the time-out counter will have 10 s left.
●
The communication link is restored for 20 s; the time-out counter will have 30 s left.
●
The communication link is disconnected again for 15 s; the time-out counter will have 15 s
left.
●
The communication link is permanently restored; the time-out counter will reach 60 s
again.
