PURPOSE:To make an instrument panel inexpensive and compact, by the constitution wherein the contents of starting inspection and periodic change parts that must be replaced can be instructed, and the items of the contents of the starting inspection, the parts to be replaced, and the like are checked. CONSTITUTION:When a main switch 4 is turned ON, starting inspection items are given to a crew by audio signal, which is synthesized by a synthesizer 17. When the starting of an engine 2 is detected by an engine rotation sensor 3, a counter 15 starts the integration of the time of usage of periodic change parts. A CPU 12 always compares the standard time of usage of each periodic change part at the time of actual usage of each periodic change part that is sequentially integrated in an RAM14. When the time of actual usage exceeds the standard time of usage, the part to be replaced is displayed on a display device 21 by a driver 16. A specified instruction sentence is formed by an ROM18 and the synthesizer 17 and announced through a speaker 23, and the part to be changed is given to the crew. The integrated time for the part in the RAM14 becomes zero by a reset switch 19, and the time of usage for the newly replaced part is integrated. |
