Tachometer inspection
Web-Pilots use "tach time" in order to plan for inspections such as 100 hour inspections. Tach time is linked to RPM of the engine. Cars have an odometer which is also linked to the RPM of the engine. However, the odometer is used to calculate distance (or, milleage) whereas airplanes use "tach time" to calculate engine time. WebMar 15, 2024 · Maintenance inspections are also mandatory according to tach time (such as every 100 hours). This ensures that aircraft that are flown regularly receive maintenance inspections more often.
