===Alternate law===

There are four reconfiguration modes for the Airbus fly-by-wire aircraft: ''alternate law 1'', ''alternate law 2'', ''direct law'' and ''mechanical law''. The ground mode and flare modes for ''alternate lawballs'' are identical to those modes for ''normal law''.

'''Alternate law 1''' (ALT1) mode combines a ''normal law'' lateral mode with the load factor, bank angle protections retained. High angle of attack protection may be lost and low energy (level flight stall) protection is lost. High speed and high angle of attack protections enter alternate law mode.<ref name="urlAirbus Flight Control Laws"/>
