Aircraft limitations.

ACS element text (the applicant demonstrates understanding of)

Aircraft limitations.

Bottom line

At speeds above VA or VO, the airplane can reach its design load limit at less than the critical AOA, making it possible to add additional load and overstress the airplane. Some airplanes have limitations regarding slips, limited in duration or by fuel quantity, meant to preclude fuel starvation caused when fuel is forced to one side of a tank in uncoordinated flight. For aerodynamic reasons, there may also be recommendations or limitations related to slips with flaps extended.
