Switching OFF the Master switch (ALT/BAT) will lead to total
failure of all electronic and electric equipment. Also affected
from this are - if installed - the attitude gyro (artificial horizon)
and the directional gyro.
However, by switching the Emergency switch ON (only
installed in the IFR model), the emergency battery will supply
power to the attitude gyro (artificial horizon) and the flood
light.
In case of extreme smoke development, the front canopy may
be unlatched during flight. This allows it to partially open, in
order to improve ventilation. The canopy will remain open in
this position. Flight characteristics will not be affected
significantly.
