While the spacing scheduling profiles are shown in an exemplary manner in FIG 5, as previously described, the variable and real time spacing schedule provided by the FADEC enables {TAIL ~ the most efficient propeller configuration} throughout the entire flight regime within noise constraint envelopes and the spacing can be continually optimized in flight for all certified airspeeds and {HEAD ~ flight trajectory angles}
