Will a Hobbs work?
I need to keep track of actual flying time of a Motor Glider. The Tach is absolutely no use since it only records engine hours and even those inacurately so when the aircrfta is gliding, there is no record of airtime. I am guessing that a Hobbs would also be connected to the engine oil pressure system by way of a switch. Is it possible to fit a hobbs directly say off of the electrical system so that a more accurate record of actual flying time is able to be recorded? Can anyone explain how a Hobbs actually works?
Any ideas would be most welcome and as the glider is on a CofA would a licensed engineer have to fit it?
