10 Internal Battery Operation
10.1 General
The internal battery consists of a rechargeable battery system with
automatic recharge, self-test, and power switching capability. The internal
battery capacity will provide approximately 2 hours of operation at
standard temperatures and 30 minutes (minimum) of operational capacity
over the operational temperature range.
10.2 Battery Transition Logic
The battery is tested, enabled, and disabled based on airspeed and
aircraft bus voltage.
10.2.1 Power-On Self-Test (Pre-Flight)
On powerup, the battery charge status will show “TEST” in amber. During
this process, an internal load is being applied to the battery to determine
general capacity capability. If the battery fails this self-test, the charge
status field will show “FAIL” in red, and no battery capability will be
available.
Figure 30- Battery Test Indicators
If the battery status shows “FAIL”, departure into actual or
planned IFR conditions must not be performed.
