Fokker60 > Flight Dynamic Test

Our products feature a 'Art of Machine' philosophy, so we are not only specially great on precise Modeling, but also strong in Flight Dynamic. We try our best to input the real data on flight dynamic files, then being the intensive flight dynamic test. A real Fokker 60 pilot said that the PAOB Fokker 60 is quite realistic!


I am pleased to say that taxiing, climbing, cruising, and landing are very smooth and the flight dynamics feel right. It’s one of the better aircraft I’ve flown in terms of dynamics. Nothing is exaggerated, such as excessive climb rates or impossible speed reduction, as I’ve seen in some turboprop aircraft add-ons. This is accomplished by utilizing the Engine Rating computer they’ve included. Engaging the AP is smooth and not jerky when first engaged.
