Final answer:
At 30 feet Radio Altitude, the flight control laws transition to landing mode; this is to prepare the aircraft for a safe touchdown and is part of the flare maneuver.
Step-by-step explanation:
In the context of flight control laws, when an aircraft is on approach for landing and enters flare mode, a specific sequence of events is triggered to safely touch down the aircraft. At 30 feet Radio Altitude (RA), the correct answer is C) The flight control laws transition to landing mode.
This transition is designed to soften the landing by adjusting the flight controls for the flare maneuver. The autopilot does not take over; it is usually already engaged if used for an auto-land scenario. Likewise, the aircraft does not inherently pitch up, and the landing gear should already be deployed well before reaching 30 ft RA by standard procedures.
The flight path of a commercial airliner follows strict Federal Aviation Administration regulations, ensuring safe operational distances between aircraft at all times, somewhat analogous to the prescribed quantum mechanical behaviors of electrons around a nucleus.
