Cool pic, thanks..
I wish vibration sensors(and chip detectors) were standard on jets...
Had a bearing go out on a Citation...picked up the vibration before the passengers felt anything, and the shut down was a low impact event...but a vibration sensor(and chip detector) might have detected the failure early, saving LOTS of money on the repairs....

Hat's off to the test pilot guys...seems that is a great job finding those limits and numbers, efficiencies...ect..
