737 pmdg overwork

[Lidan 0]

Hello, everybody I have a big problem with the 737 I fly the 900 er engine overworked at cruising and climbing at cruising I get 95% of trust with only 58 zfw end 13 tons of fuel I tried everything I checked thousand times with tutorials. I don’t do nothing wrong, but I can’t solve it please help me.

The first question would be, how high are you trying to climb?  On the cruise page of the FMC you'll see two altitudes listed: optimum and max.  You really don't want to climb much above optimum.  You likely will not be able to climb above max.

It's probably me, but what exactly is the problem ?

Got any screenshots or videos pointing out your issue, as I'm sensing this probably comes down to misunderstanding the 737

I’m flying optimal conditions always and do an Econ climb

Not just you - I had the same response...lol

Oh, I think I get it?

High engine thrust setting at cruise - are you sure the gear, flaps and or spoilers aren't deployed? Thrust (using autothrottle and VNAV or FLT LVL Change) will always be high during climb. If you are using a really high cost index, or set a high cruise mach setting you will see high thrust. I think I've only ever seen around 90% in cruise, and it's usually more like 80% - 85%. Thrust required to cruise at a given speed will also vary depending on altitude.

I’m climbing and cruising Econ mode and do takeoff and climb derate when the aircraft switch from TO trust to CLB it starts from something around 94% and after 20,000 feet is very close to 100 sometimes it’s past 100% and that cruising between 96 to 94 and not like you said 80% to 90% it’s can be a problem in the throttle quadrant of logitech

Just a suggestion, but why don't you ask this question over at the PMDG forum?

Why not?

With 94% - 96% thrust in cruise at what altitude and mach value are you cruising?

[threexgreen 3,152]

Thrust around 100% during climb is normal. If thrust is 95-ish% during cruise and you're maintaining speed you're probably going very fast or flying close to max altitude, maybe a combination of that or even very high headwinds. If you put in a high CI you will still be fast in cruise even if you're flying at ECON cruise for that CI.

Need more info; screenshots of the relevant FMC pages and displays would be helpful to spot if something is off in the setup.

But what altitude are you climbing to, compared to optimum and max?  It's not about the conditions you're climbing in, but what altitude you're trying to reach, reference your weight and speed.
