SECTION 5 CONFORMANCE
5.1 DISPATCH VERIFICATION AND IN-FLIGHT MONITORING
The main ship battery typically serves two primary purposes: engine start and emergency backup
power.
Engine Start: In order to attempt an engine start, the user should verify that the FAULT signal is
not active. It is also recommended that the battery be fully pre-heated (HEATING signal not
active) for an engine start. If used, the pre-programmed Engine Start indicator can also be used
to verify that the battery is ready to start an engine.
Dispatch for Emergency Backup Power: If the aircraft has a minimum backup power requirement
for loss of aircraft electrical generation in emergency operation, the user may need to verify
battery capacity prior to flight. This can be done in various ways, possibly including an SOC
verification or verifying the Minimum Capacity indicator. Check with the aircraft operating
requirements for specific procedures. Once battery capacity is verified as sufficient, the battery is
ready for dispatch.
During flight, the battery is capable of providing a number of status indications and health
monitoring information to the cockpit or crew through its communication outputs (see Section 4.4).
In-Flight Monitoring: Typically, all annunciations from the unit should be inactive during flight.
However, the HEATING signal may be observed depending on the temperature of the unit and
does not represent a hazard or loss of function. An indication of the FAULT signal or
independent monitoring of the RTD sensors could require action or degraded function. Consult
your aircraft flight manual for details.
5.2 INSTRUCTIONS FOR CONTINUED AIRWORTHINESS
No periodic scheduled maintenance is necessary for continued airworthiness of the TBX series
Advanced Lithium-ion Batteries. If the battery is stored for more than six (6) months, refer to
Section 5.4.2 for charging instructions. If the unit fails to perform to specifications, the unit must be
removed and serviced by True Blue Power or their authorized designee.
True Blue Power will have, on occasion, the need to update the software of the TBX series
Advanced Lithium-ion Batteries to improve and/or enhance functionality or performance.
With the TBX Battery’s easy field-upgrade option, the unit does not have to be returned to the
factory, and in most cases, may not have to be removed from its installation.
Software updates are typically communicated to the public via Service Bulletins issued by True
Blue Power and can be found on the product website
www.truebluepowerusa.com
. Refer to
Section 5.3 for updating the TBX series Advanced Lithium-ion Battery software.
