Line 44:
The flight mode of ''normal law'' provides five types of protection: pitch attitude, load factor limitations, high speed, high-[[angle of attack|AOA]] and [[bank angle]]. ''Flight mode'' is operational from take-off, until shortly before the aircraft lands, around 100 feet above ground level. It can be lost prematurely as a result of pilot commands or system failures. Loss of ''normal law'' as a result of a system failure results in ''alternate law 1'' or ''2''.<ref name="urlAirbus Flight Control Laws">{{cite web |url=http://www.airbusdriver.net/airbus_fltlaws.htm |title=Airbus Flight Control Laws }}</ref>
Unlike conventional controls, in ''normal law'' vertical side stick movement corresponds to a load factor proportional to stick deflection independent of aircraft speed. When the stick is neutral and the load factor is 1g, the aircraft remains in level flight without the pilot changing the elevator trim. Horizontal side stick movement commands a roll rate, and the aircraft maintains a proper pitch angle once a turn has been established, up to 33° bank. The system prevents further trim up when the [[angle of attack]] is excessive, the load factor exceeds 1.3g, or when the bank angle exceeds 33°.{{Citation needed|date=October 2013}}
Alpha protection (α-Prot) prevents stalling and guards against the effects of windshear. The protection engages when the angle of attack is between α-Prot and α-Max and limits the angle of attack commanded by the pilot's sidestick or, if autopilot is engaged, it disengages the autopilot.{{Citation needed|date=October 2013}}
