Which characteristic best describes "transverse stability"?

Transverse stability, commonly referred to as lateral stability, primarily concerns an aircraft's ability to maintain balance during rolling motion. This characteristic is vital for the aircraft's behavior during maneuvers that involve lateral control. When an aircraft is subjected to external forces or disturbances that cause it to roll, transverse stability will determine how effectively it can return to a level flight position without excessive intervention from the pilot.

For instance, when an aircraft begins to roll due to turbulence, strong transverse stability enables it to resist that rolling motion and naturally return to a wings-level attitude. This is achieved through the design of the aircraft, including the placement and size of the wings and the distribution of weight. Hence, transverse stability is crucial for flight safety and control, especially in conditions that may induce rolling moments. It ensures that pilots can manage their aircraft more efficiently, particularly during turns or in response to gusts of wind.
