Emergency procedures
BPRS
Please refer to Appendix (9-2) for information about the use of Ballistic Parachute Rescue
System during emergency.
Battery failure
With two battery packs on board the battery system is automatically redundant. A failure of one
battery pack will be displayed on EPSI570 as a warning and the system will automatically switch
to a single-battery mode, enabling continuation of flight. Land as soon as practical and have the
battery system verified by authorised personnel.
WARNING! Single battery operation is considered an emergency situation in which the
maximum power output must be kept below 35 kW! Plan actions and maneuvers accordingly.

Powertrain components overtemperature
Continuous monitoring and a careful management (power setting) of powertrain components tem-
perature is essential for flight safety. Motor, power controller and battery temperatures are displayed
on the EPSI570 screen in the form of vertical bar-type indicators. Temperature ranges (normal, cau-
tion, warning) are indicated beside each vertical bar. Please see Section 2 - Limitations - Motor instru-
ment markings - for applicable temperature range values.
