Heliduck - thanks. If what you say is true, I am going to scold Eurocopter Maintenance (they have a venerable guru who knows EVERYTHING about 350's) and 2 other large-ish maintenance organisations who also didn't know about this. Then I am going to tell the solution to half a dozen professional pilots I consulted including 2 with well over 10,000 hours about this. To think I could have spent thousands replacing the TQ meter!!
Where is the transducer?
Thanks again - I love the internet, PPRUNE and your reply.
