Hello,
I'm sorry, did not work also.
Maybe it is the saved "cold and dark" status I created saving a aircraft-status from a "cold and dark" cessna.

A workaround is another saved aircraft-status with engine/pwr OFF but avionics ON.

It seems that the avionics OFF status is something like an undefined status that doesn't work for the F-104.

Anyway, a great plane and thanks for reply.

Greetings from the 104G homeland  ;)
