A number of ideas we have long taken for granted are going out the window. For instance, no more Utility and Acrobatic categories. No more 6,000- and 12,500-pound weight cutoffs. Instead, the Normal category — the only survivor of the old trio — will be divided into four levels by the number of passengers carried, respectively zero to one, two to six, seven to nine and 10 to 19. Two performance levels are proposed, based on maximum cruising speed; the break is at 250 kcas or Mach 0.6. A special place is reserved for “simple” airplanes, defined as VFR-only Level 1 airplanes, under 45 kcas stalling speed (and under 250 kcas cruise, though the simple class seems to be intended for LSA-type airplanes, not some as-yet-undesigned device that stalls at 44 knots and cruises at 249). The type of propulsion is no longer a factor.
