LOPI affects warnings during which phase?

• A. From 400 feet AGL to 50 knots on landing rollout or 30 seconds after touchdown
• B. From 80 knots to 400 feet AGL on takeoff
• C. From touchdown to taxi
• D. Only during approach

Answer: (A)

LOPI warnings are tied to the most critical moment when navigation data must be trusted near the ground. The system activates these warnings from 400 feet AGL down to the end of the landing rollout, specifically until you reach 50 knots on rollout or up to 30 seconds after touchdown. This window covers the final approach, flare, and early rollout when proximity to the surface and reduced airspeed make accurate position information essential and when pilots are transitioning to ground operations. Outside this interval, the risk emphasis decreases, so the warnings are not needed as actively. In short, the warnings are focused on the late approach through the initial landing rollout, not on takeoff, nor only during approach, nor after touchdown.
