I thought I once saw a Hobbs flight time meter in the TBM, but searching everywhere I cannot see one. The real plane has one above the circuit breaker panel. Also no dedicated avionics master switch, but I don’t think it exists in the real bird. Thoughts? Thanks!

You can find the hours for each individual plane (including community folder aircraft) in you local cahce folder (…8bbwe\LocalCache\SimObjects for MS version) For steam it will be in roaming (mine is in \Users\XXXXX\AppData\Roaming\Microsoft Flight Simulator\SimObjects\ ). Select the plane in there to see it's state.CFG file which contains flight and hobbs hours.
