QualityWings 757 - flight dynamics

Recommended Posts

Hi,

I am used to fly the PMDG 737-800 and like the immersive and realistic aircraft. 

I now got the Quality Wings 757. Easy to install (just for once for FSX), and it feels kinda realistic. As in the real world, the 757 is slightly overpowered. 

But there are two things that I wondered on how realistic that is in respect of its behavior: 

1. After startup, the aircraft moves upon parking brake release in IDLE power? It's a plane that was fully loaded with cargo and fuel. 

2. When adding thrust during takeoff, the plane would take-off by itself without pilot intervention and that isnt at overspeed, but pretty close to v1/vr. 

Would be great, if anybody could comment on that.  

Cheers,

On RR engines rated at about 43,000 lbs of thrust when fully loaded, it will start moving after brake release on a level ramp (no incline) after about 20 seconds at idle.
The 2nd scenario you described is related to a wrong elevator trim setting calculation (out-of-trim situation). 
Many of us loved flying that airplane, it was/is a Ferrari,  unfortunately, passenger-wise comfort leaves nothing to be desired.

Thanks so much for your insights! Much appreciated. So it is quite realistic what i experienced. 

The over-engineering of the engines was quite obvious given how quickly I went to overspeed. Needs careful handling! 

Im not an expert and not claim to be one, but it seems to me that this "overdrive" has benefits like a higher safety margin and shorter runways lengths needed, but isnt the downside a high fuel consumption? What was the intentiion behind it? In comparison, the PMDG 737-8 is pretty lame. 🙂

It never was meant to be a study level representation of the 757, but it was fun to fly as long as you stayed ahead of it and didn't rely too much on the autopilot.
