Bonjour Sierra,
Voici un élément de réponse trouvé sur le site suivant:
http://avia.russian.ee/theory/bell-407/cockpit.html
The engine instruments are arranged in two vertical rows just to the left of the flight instruments, with the three most important ones right next to the airspeed indicator and dual tachometer.
At the top is the torquemeter, which indicates directly how much power is being supplied to the rotor. This is your primary power setting instrument, and is affected directly by movement of the collective.
Next down is MGT, which stands for Measured Gas Temperature—the temperature of the stream of hot gas in the engine. While the torquemeter is your power setting instrument, MGT is your power limiting instrument: at higher temperatures and/or altitudes, you may reach limiting engine temperature before you have obtained all the torque you might like. In this case, you'll just have to be content with what power (torque) you can obtain. You'll notice a couple of red markings beyond the redline. The first, at 843 degrees, is a start limit; you should abort an engine start if MGT goes above this mark for more than a couple of seconds. The second, at 905 degrees, is an absolute limit beyond which any engine operation will be recorded immediately as an exceedance.
Désolé pour la version anglaise :?
