Which instability during aircraft landing increases due to ground effect?

💡 Explanation

Pilot induced oscillation susceptibility increases because ground effect alters airflow, reducing the damping of pitch oscillations; therefore, even minor pilot corrections amplify these oscillations, rather than stabilizing controls because altitude is decreased.
