← TechnologyDuring steep descent in icing conditions, which outcome occurs when horizontal stabilizer effectiveness significantly decreases?
A)Pilot-induced oscillation greatly increases✓
B)Lift-induced drag becomes insignificant
C)Engine flameout becomes more likely
D)Airspeed indication is significantly dampened
💡 Explanation
Pilot-induced oscillation increases because **runaway trim** occurs when horizontal stabilizer icing decreases pitch control effectiveness, causing pilots to overcorrect. Therefore, overcorrection worsens oscillation rather than stabilizing it; the effect is exacerbated in steep descents.
