Manuevering Speed
VA is defined for evaluating aircraft structural design. At or below this speed, Boeing aircraft are capable of sustaining a single input to any set of control surfaces to their maximum available authority. These control surface inputs are to be in one axis and do not include control input reversal or oscillatory inputs.
Even at speeds below VA, transport category aircraft should be flown judicioulsy, avoaiding full or abrupt control movements.
Turbulence Penetration Speed can be used as a rough approximation for VA

Icing Caution
Do not rely on airframe visual icing cues to turn engine anti-ice on. Delaying the use of engine anti-ice until ice buildup is visible from the flightdeck may result in severe engine damage.
Engine Anti-Ice
Engine anti-ice must be on during all ground and flight operations when icing conditions exist or are anticipated, except during climb and cruise when the temperatue is below -40 Degrees Celsius SAT. Engine anti-ice must be on prior to and during descent in all Icing Conditions, including temperatures below -40 Degrees Celsius SAT.
