Thanks all...sorry for the late reply..being away for a while. I never noticed reduction in taxi speed with use of props from full fine to feather. However, a few new captains seem to want to feather the engine every chance they get...maybe to impress a few pax!!!!
Gets abit irritating especially when all they seem to do is play around with prop pitch while taxiing. Only reason they give when questioned about the procedure is "it slows the aircraft down"!!!! Well...i for one dont see no change in taxi speed!! And then one comes up with "as soon as I feather the engine and apply brakes, the aircraft does slow down"!!! Well.. damn that...who would have ever thought applying brakes would slow an aircraft down!! Feel like throwing the SOPs book at their face!!!
ANyway...thanks again for your help.
