YACS Control Switch
In the event of a failure in the control system, the
YACS control switch enables the operator to switch
the control to manual mode, similar to piloted air-
craft. Normally, this is kept "ON".
If the control system fails despite its various built-in
safety features, calmly turn this switch OFF and
land the helicopter at a safe location in manual
mode.
When the YACS control switch is OFF, the buzzer in
the transmitter will emit a "beep-beep" sound to
inform the operator that control is in manual mode.
Turning
the
switches to manual mode. Do not confuse
with other switches while operating.
GPS Control Switch
The GPS control switch is used for switching
between the following modes: A
⇔
SG. (See page 4-13.)
Before turning ON the GPS control switch, make
sure that the outer lights of the GPS indicator are
illuminated. If the GPS indicator lights are OFF or
flashing, the GPS control flight mode cannot be
used even when the GPS control switch is turned
ON.
Moreover, in the situations described below, first
turn OFF the switch, then turn it back ON. Other-
wise, the GPS control flight mode cannot be used.
• GPS control communication has been interrupted
because the helicopter has landed.
• The GPS control switch was ON even before
takeoff.
• GPS control has been interrupted due to poor
GPS signal reception.
• GPS control has been interrupted because it has
been set to manual mode.
