In the case of alternate law due to multiple system failures, which characteristic is true?

In alternate law, the aircraft transitions from normal law to a more basic level of flight envelope protection due to multiple system failures. One of the notable characteristics of alternate law is that the flare mode, which assists the pilot during landing by helping to control pitch during flare, is indeed not available. This is because alternate law is a simplified control mode that does not provide the same level of automatic protections or assistance that are available in normal law.

Understanding why the flare mode is absent underlines the limitations of alternate law—while the aircraft can still be flown and controlled, it requires more pilot input and care, especially during critical phases like landing. The absence of the flare mode signifies reduced capabilities in terms of automated pitch control during landing.

The other characteristics mentioned highlight differences in the performance and operational behavior of the aircraft in alternate law compared to normal law. For instance, in alternate law, the control commands are different; they focus on maintaining a basic level of control but do not include all the protective features pilots might expect in normal law.
