Pre-takeoff checklist
Is the GTX 327 serial output sufficient to proved altitude data to a GPS or does this need to come directly from the encoder? I currently have a Narco AR850 encoder which doesn't have a serial interface. I was wondering whether it needs to be replace it with, something like a Trans Call with RS232 or will the GTX pass along the altitude from the Narco in serial format as the Trans Cal does?
