Which of the following best describes the flare mode?

The flare mode is an essential part of the airplane's autoland system designed to ensure a smooth touchdown. When the aircraft reaches 30 feet above the ground, the flare mode automatically reduces the pitch of the airplane, helping to ensure that the aircraft descends at the optimal angle and rate for landing. This action significantly aids in controlling the landing profile, ultimately contributing to a safer and more stable landing.

The mention of engaging at 100 feet above the ground pertains to the approach phase rather than the flare phase itself. While the flare is critical, it specifically activates at a lower altitude. The implication that it eliminates the need for the pilot to flare oversimplifies the role of the pilot during landing; pilots still play a crucial role even with automated systems. Finally, availability in direct law refers to another aspect of flight control modes and does not pertain directly to the flare function, which operates under the autoland capability.
