Federal Aviation Administration, DOT Pt. 121, App. M The recorded values must meet the designated range, resolution and accuracy requirements during static and dynamic conditions. Dynamic condition means the parameter is experiencing change at the maximum rate attainable, including the maximum rate of reversal. All data recorded must be correlated in time to within one second. Parameters Range Accuracy (sensor input) Seconds per sampling interval 63. Engine warning each engine over temp. 64. Engine warning each engine oil pressure low. 65. Engine warning each engine over speed. 66. Yaw Trim Surface Position.
