Is this the same Army that put out thousands of "Tactical Instrument Rated" pilots during a period of unpleasantness in the Southeastern part of Asia? The same Army that spent countless hours of valuable training time teaching the figure eight tactical instrument approach that was dead certain to cause veritigo and/or disorientation over,around, near, an NDB or Field radion transmitter? The same Army that lost hundreds of helicopters to weather related accidents and killed a swoop of people as a result of those policies invented by MGEN Tolson of 1st Air Cav fame and later a bigwig in the NCARNG?
Who got to ride home in the center seat of a pickup truck one afternoon because a young Army warrant officer would not violate regulations and fly a UH-1 from Charlotte to Raleigh IFR.....that same Army? (Was a proud holder of one of those wonderful TAC tickets.....and could not miss the opporunity to make a point....a Standard ticket would have prevented that problem....) We started getting Instrument school slots immediately after that as I recall.
There is something to the study...but I dare say 60 knots is a tad high.....also different aircraft will handle better if configured with stability augmentation than the old Huey...god bless her!
