Multiple FU91 installation
The operation of each lever is identical to above description of a single lever.
Activating one FU91 will deactivate the one that was previously active.
FU91 and S9 connected to the same autopilot
It is recommended not to have both S9 and FU91 in operational condition at the
same time. This may create confusion and inadvertent operation. The main rules
are:
• Always put the S9 lever to locked position after use .
• Always switch the FU91 to OFF after use.
