Final answer:
The query pertains to the existence of Roll Alternate Law in fly-by-wire aircraft control systems. Roll Alternate Law is a degraded mode that offers manual roll control to pilots without full bank angle protection.
Step-by-step explanation:
The subject of this question revolves around flight control laws specific to aircraft flight control systems. In modern fly-by-wire systems, such as those found in Airbus aircraft, there are different laws that dictate how the aircraft responds to pilot inputs. One of these laws is indeed the Roll Alternate Law. This law comes into effect when there's a failure that degrades the normal law without compromising the aircraft's safety. During roll alternate law, protections such as bank angle protection are lost, but the pilot can still control the aircraft's roll movement manually. It acts as a middle ground between the normal and direct laws, offering more manual control than normal law but with some level of automated protection remaining.
Yes, there is a roll alternate law in flight control systems.
The roll alternate law is a mode of operation in the flight control system of an aircraft. In this mode, the aircraft's roll control is partially or entirely dependent on the pilot's inputs rather than being fully automated.
This mode is employed in certain situations, such as when there is a failure or degradation in the primary flight control system. The roll alternate law allows the pilot to retain some level of control over the aircraft's roll movements, ensuring safer flight operations.
