In icing conditions, a roll upset can happen even when you don’t see ice or feel the typical stall cues. Ice contamination can be hidden on leading edges or control surfaces, or one wing can accumulate more ice than the other, creating an asymmetric condition that produces an abrupt roll or a loss of roll authority. You might not get the usual signs like visible ice buildup or buffet, yet the airplane can roll unexpectedly.

That’s why this statement is correct: you must stay prepared for roll disturbances that aren’t preceded by the familiar ice-visible cues or stall sensations. Monitor flight instruments and airplane behavior closely, and follow approved procedures to restore wings-level flight and reduce icing effects, rather than relying on appearance or expected stall symptoms alone.
