instantly stall break aircraft attitude exit/recovery behavior indicators However its much harder explain demonstrate its difficult ascertain judge spectator person flying airplane best signs true spin descent path recovery spin aircraft descends vertical path nearly intersects CG aircraft spiral dive CC describes muchlarger-diameter corkscrew path spiral dive recovery will instant controls

aircraft should raise slightly flat spin should develop Some airplanes will flat-spin extremely shallow nose-down attitudes rate fuselage will much flatter attitude normal spin descent rate will noticeably less flat spin normal spin certain aircraft flat spin can made flatter releasing possibly reversing elevator and/or adding bit throttle Others may recover fall back normal spin control changes Only flight testing will tell certain what airplane will first attempts flat spin dont wait too long initiate recovery Its easy get mesmerized maneuver allow room recovery After few turns flat
