Winter / Focus / Fuel/Electric.

[Bob Pastorello]

If anyone is running MS Flight Sim 2000 or later, you can do the prop pitch change at low throttle, and watch the VSI.  I think it is a "real physics" simulation of pitch moments caused by drag and lift changes...

    John, 

    If you want to see a dramatic difference in drag of the windmilling prop in a full scale Cessna, try this.  Use an aircraft with a constant speed prop, set up for best glide speed with the power off.  When you have this done with the engine at idle, note the number on the VSI.  Then pull the prop all the way out, you will see a pitch up and a smaller number on the VSI.  This gives the effect of a feathered prop in a single.  We are also taught that in multiengine aircraft that if you can't feather the prop of the dead engine, it provides a lot of drag on the dead engine side and in a real engine out situation it will really hurt you.

    See ya,
