This invention relates to a tandem or multi-winged aircraft wherein a primary wing system is so designed and equipped that it is capable of being actuated in a manner to bring about a shift in the neutral point of the craft relative to its center of gravity and wherein a secondary wing system located ahead of the primary one and movable fore and aft relative to the latter is deployed and angled during its excursion so as to effectively counteract the neutral point shift that would be brought about by deploying the primary wing system alone thereby maintaining the neutral point at approximately its former location in at least both the cruise mode as well as the high-lift mode preferred for landing and take-off.
