3.2.3
Substitution of Rate-Of-Turn Indicator
The KI 300 may be eligible to replace the Rate-Of-Turn Indicator in certain applications. Refer to FAA AC
91-75 for additional details.
3.2.4
Battery Operation
The battery sub-system in the KI 300 is designed to fulfill the needs of an independent power source per
14 CFR 23.1353(h). Considerations are as follows:
Automatic transition to battery will occur if the externally supplied power drops below
approximately 7 VDC.
A load-test is performed on each power-on cycle - a faulted battery indication will be shown if
this test fails.
Battery operational time is highly dependent on the ambient operating temperature and
backlight intensity settings. See the specifications section in this document for minimum
guaranteed operating time under different conditions.
Reference the KI 300 Pilots Guide (PN 89000004-201) for additional details on battery operation.
3.2.5
Functional Dependencies
The KI 300 is not sensitive to external magnetic fields. Altitude indication requires correct static
pressure. Airspeed indication requires both correct pitot and correct static pressure. Slip indication has
no functional dependencies.
3.2.6
