Hello,
What is FDS going to be doing about the Props on the Dash 8, as an extensive P3D and FSX User of the Dash 8, I understand the Prop Settings of “Start and Feather” and the Props 800 and 1000.
Does anyone know if the props will just be at 1000 all of the time or a button to change the condition leavers?
Thanks
So the propellers aren’t of automatic variable pitch?
Nobody will know until the release.
What does this even mean. Prop, variable pitch and so on. Why does the Dash-8 have two throttles?
Sorry this is reviving an old post, however I couldn’t find the answer elsewhere and with todays incident in EHAM I’m interested in the DASH-8
The propeller on the Dash-8 can change the angle it cuts into the air. See Understanding Variable Pitch Propellers - Hartzell Propeller (vid) for more, but as a summary, the fixed-blade prop (prop cannot change the angle it cuts into the air) is more inefficient than a variable pitch prop as it must be optimised for all stages of flight while the variable pitch one can change to suit the conditions.
In the event of a engine failure, this prop is now causing huge amounts of drag as it is angled against the flow of air. This can be solved by “feathering” the props to turn them towards the direction of the incoming air, thus reducing drag and allowing a turboprop with a double engine failure to glide further. Tuninter Flight 1153 - Wikipedia this was a ATR72 that would have possibly made it to safety if the pilots had remembered to feather the prop.
If I remember correctly Rolls is developing a variable pitch turbofan where the blades on the N1 fan can be changed but I might be wrong.
