Third, if we roll to a stop and leave the props in feather, there is a chance that our hot exhaust gases will not be blown safely away, but may negatively impact the nacelle and nose paint, oil temperature, as well as cause overheating of the nose-mounted avionics boxes. Remember to push those prop levers forward when stopped.
This in-and-out of feathering while taxiing is especially useful is we have found that our dead band is too small – N1 is picking up too early – yet the mechanic has not yet had time to adjust it properly. It is easy to taxi without residual thrust, no matter how messed up our rigging is, by using the feathering technique.
Also, remember this useful “trick.” When starting to taxi, if the airplane does not begin to roll when the brakes are released, try a quick in-and-out feathering instead of an application of power. Isn’t that cool?! The momentary bigger bite of air is just what was needed to make the plane begin to roll, yet with zero chance of blade erosion.
