← TechnologyWhich mechanism causes increased landing distance when an aircraft encounters a tailwind?
A)Increased ground speed requirement✓
B)Decreased lift-to-drag ratio
C)Elevated engine thrust reduction
D)Reduced aerodynamic braking effectiveness
💡 Explanation
A tailwind increases the aircraft's ground speed during landing due to vector addition. This requires a higher velocity to achieve lift-off, therefore more runway is used. Thus, the increased ground speed requirement extends landing distance, rather than changes in lift or braking under normal operation.
