Derated temperature
WebAug 16, 2024 · It can be done by limiting the applied voltage to around 50% below the rated voltage. This type of derating is called voltage derating. The other derating method is to limit the temperature to 15℃ below the maximum rated operating temperature; this method is called temperature derating. Ceramic Capacitor Derating Voltage WebMay 5, 2009 · I don't know about derated thrust (derated thrust and assumed temperature are two different things. You can use derated thrust without using assumed temperature). If we're talking about thrust reduction using assumed temperature (Airbus calls it FLEXIBLE TAKEOFF THRUST), it can only be used if the aircraft weight is lower than its maximum ...
