PURPOSE:To facilitate the production of a hard copy while heightening the reliability of a maintenance data by measuring and memorizing continuation time at each level of fatigue accelerating stress employing an IC electronic equipment such as CPU, EAROM, ROM and RAM. CONSTITUTION:An accelerometer I detects acceleration given an aircraft during the flight and an acceleration data processed and discriminated with a CPU 11 is sent to an electrically erasable and writable memory EAROM 12 to be memorized. A time pulse generation module 21 mainly composed of a quartz oscillator outputs a clock signal to the CPU 11 through an interface circuit 10 to provide exact time information and the signal is memorized into the EAROM 12 together with the processed acceleration data. A data collector III inputs various data transmitted in a multiplex fashion to corresponding counting display elements 16 to be displayed while sending them to a printer 17 for printing out to obtain a hard copy. |
