When is LAND INHIBIT active?

The LAND INHIBIT function is specifically related to the aircraft's autoland capability and is designed to prevent unwanted system responses in critical phases of landing. It becomes active from 800 feet AGL (Above Ground Level) to 80 knots during the landing roll.

This specific range is important because it ensures that the autoland system remains engaged during the most crucial moments of the landing sequence while also providing pilots with the opportunity to take manual control of the aircraft as it approaches the ground. Once the aircraft descends below 800 feet AGL, the system limits automated interventions to allow pilots to have a greater control when they are closer to the ground and the speed is reducing.

In this context, other options indicate different altitudes or phases, yet they do not align with the specific operational parameters of the LAND INHIBIT function, which is uniquely designed for the range from 800 feet to 80 knots, making B the accurate choice.
