Osprey engines shut off after takeoff

Robert,

This is a feature, not a bug - and its described in the product manual, FAQs and description:

My engines die mid flight!
This is in fact a feature, not a bug. As described in the aircraft manual: "Engines can afford high RPM (> 98% Ng) for a maximum period of 60 seconds continuously. Any longer and the engines will be damaged and shut down. This simulates the real counterpart, which can stand limited amounts of time at high RPM. Engine limitations can be deactivated by switching “Flight Reality” to EASY on the CDU.". Visual queues have been recently added: Interm power on your PFD will blink red to alert the pilot flying of potential damage to the engine. If this indicator blinks red for more than a few seconds, the engines will fail due to overstress.

Please refer to the manual, available here: https://uploads-ssl.webflow.com/630171340347ba4f0fff8279/6428e8a969d01c0e3216c3f9_MS Osprey MV22 - Manual.pdf
Pages 10 and 16

As mentioned above, this occurs when the flight mode is set to "HARD". It can be deactivated by setting it to "EASY" mode on the CDU.
