- With these limitations, however, it is still possible to obtain acoustic information useful in analyzing several aspects of the aircraft, including engine speed, propeller rotational speed, rotor speed, transmission operation, hydraulic pump operation, and ground speed. This information may be recorded on the cockpit area microphone channel. While it is possible to analyze the sounds and make accurate calculations, it is not usually possible to determine precise location of an acoustic source using the cockpit area microphone recording, because it is a single source recording. It is also not possible to determine, for instance, which engine failed in an engine failure – the recording would simply show a signal reducing in frequency, but it is not possible to determine from the recording if it is the left, right or center engine.
