P/N Engine Recorder Reading

The P/N Engine Recorder Reading window allows users to view/enter an engine recorder's measurements. This information is compiled into transactions that affect Rotor Wing Aircraft tracking formulas. Recorders can be moved from one engine to another and the data can be reset to '0' (this data is automatically reset to '0' after passing '10000'). The data from this window generates transaction numbers which can be used by the formulas created in the Formulas window.

This window is security-controlled via Technical Records/ Update/ P/N Engine Recorder Reading. For more information refer to the Security Explorer via the System Administration Training Manual.

The following information/options are available in this window:

Low Cycle Fatigue2 (LCF2)

The thermal cycles that measure the number of times an engine experiences reduced mechanical stress. Depending on manufacturer specifications, this may be limited to the amount of time the NG (Gas Producer Cycles) exceeds a certain percentage.

Recorder Index

Measures increases or decreases in temperature per minute based on specific temperature ranges.

Engine Operating Hours

The amount of hours an engine is running. Depending on manufacturer specifications, this may be limited to the amount of time the NG (Gas Producer Cycles) exceeds a certain percentage.
