Hey folks,
I suspect my airplane may have one 2500 RPM tach and one 2300 RPM tach installed and I am wondering which is right. Both tachs have been replaced multiple times in my airplane's life, and any documentation for what came from the factory is long gone by now. Does anyone here have any specific knowledge? (1977 Seneca II)
For those that do not know what I am talking about, I'm referring to the RPM at which the Tachometer's hourmeter odometer counts accurate to real time. I am NOT referring to markings on the face of the instrument.
Any thoughts are appreciated.
Thanks!
