← TechnologyWhich mechanism precipitates a 'hard landing' when aircraft landing gear fails to fully extend?
A)Airflow stall about the wing
B)Elevator control surface lockup
C)Ground effect disruption increases
D)Impact force exceeds strut damping✓
💡 Explanation
A 'hard landing' occurs because insufficient landing gear extension results in greatly reduced or absent shock absorption. The impact force exceeds the *damping capacity* of the shortened or absent strut; therefore excessive force is transmitted; rather than dissipated in controlled compression.
