← TechnologyDuring an aircraft landing with deactivated spoilers, which consequence results from the delayed deployment of reverse thrust?
A)Increased ground roll distance✓
B)Decreased airframe stress
C)Enhanced elevator authority
D)Reduced engine wear rate
💡 Explanation
Increased ground roll occurs because delayed reverse thrust reduces the deceleration, diminishing the retarding force. The *ground friction coefficient* remains the primary slowing mechanism; therefore, roll distance increases rather than decreasing stress from braking or impacting engine component wear.
