Gen 1 Incident Recorder Design Parameters

•Design Features

-Records nine engine and aircraft parameters.

-Records basic engine and aircraft information for approximately the last 1 1/2 hours of engine operation.

-Begins recording when the start initiates.

-Stops recording after engine shutdown or 5 minutes after Weight on Wheels (WOW) is true (On ground).

•Data is collected in “Buckets” to indicate parameter range

-

-

-

i.e. The N1 speed was between 75 and 80% maximum speed. This allowed data to fit into available memory.

Medium to High Fidelity data.

•Data Resolution

-Data is collected at increasing intervals from the end of the data stream starting at one second intervals.

-This allowed for the most recent data to have the highest fidelity while maximizing the data stream available for download.
