While the spacing scheduling profiles are shown in {HEAD ~ an exemplary manner} in FIG 5, as previously described, the variable and real time spacing schedule provided by {TAIL ~ the FADEC} enables 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 flight trajectory angles
