Yes, an airplane can be stalled in alternate law due to the reduction or loss of flight control protections that prevent stalling under normal law conditions. Pilots must manual fly with increased caution in alternate law.
Can an airplane be stalled in alternate law? When an aircraft is in 'alternate law', it refers to an alternate set of flight control laws that become active when specific systems failures occur.
In normal law, the flight control systems of modern fly-by-wire aircraft, such as those from Airbus, incorporate protections against stalling.
However, in alternate law, some of these protections may be lost or degraded.
As a result, it is indeed possible for an airplane to enter a stall under alternate law if the pilot fails to maintain adequate airspeed. It's important for pilots to be aware of the aircraft's state and to fly manually with greater caution if they find themselves in alternate law.
Just as the Federal Aviation Administration strictly controls the flight path of commercial airliners, pilots must control their aircraft's airspeed and adhere to operational limits to ensure safety.
