7.24 EMC TEST PROCEDURE
NOTE: This test must be conducted with the aircraft engines operating and rotors turning
(100% rotor speed at flat pitch).
For additional guidance on conducting EMC testing, refer to AC 43.13-1B Chapter 11, Section
8.
With the ST3400H in normal operation, evaluate all of the aircraft equipment for proper
operation to ensure that there is no interference from the ST3400H. Evaluate each equipment
item for spurious operation; i.e unexpected needle deflection, unexpected changes in data, or
other erroneous operation. Additional space is provided for equipment not listed.

7.25 AUDIO TEST
NOTE: This test must be conducted with the aircraft engines operating and rotors turning
(100% rotor speed at flat pitch).
NOTE: Aural alerts for situations requiring immediate action by the flight crew should
have priority in situations where conditions for multiple alerts may occur. Older aircraft
audio system architectures may not prioritize aural alerts for multiple alerting systems. If
such is the case, an aural prioritization scheme may not be available. However, if
simultaneous alerts can be given, then the alerts must be understandable and
distinguishable.
