MCT vs Max Cruise Thrust
 

Hi , just wondering if anyone can enlighten me on the following point , taking into consideration I fly a Beechjet ......or if the below holds good for all jet aircraft ?

BELOW STATEMENT TO BE CONSIDERED AT FL410 :

1.Why is it that the Max continous thrust ( 103.2% n1 ) as per the MCT chart is less than the Max Cruise Thrust permitted ( 104.0% n1) ??

The above is causing me confusion , as Max continuos in my mind means THE MAXIMUM CONTINOUS THRUST that can be produced by the engine ..... therefore it should be higher than the Max Cruise thrust !!!!

Thanks in advace , all relevant replies welcomed.

On my aircraft, the MCT is also different than Max Cruise. It depends on the agreement with the engine manufacturer/overhauler as to what value is used continuously during cruise situations.

In other words, it's a warranty issue. MCT is allowed anytime, but not as a continuous value for cruise.

..... with all engines, with an engine out you can use MCT all day long.
