Im puzzled by the term "climb thrust" while reading a book, for an airliner to climb, throttle would be set to a specific climb thrust, when it gets higher, air is less dense, the thrust producing by the engines should be less. (Coz im flying a warrior and trying to appply same principles to a turbofan engine) Now, what Im asking is, do the engines actually spin faster to produce same "climb thrust" as lower altitude or just let it decrease?
And during a climb, IAS would be kept the same but TAS is increasing, is it becasue you can fly faster when LESS DRAG is experienced even though your engines are giving less thrust/same thrust?
I really dont get the idea when you can fly faster with less thrust but I also doubt that the engines will keep up the thrust while climbing coz there must be an end that the engines cant work any harder.
correct me if im wrong......
