Failure of stall warning with unreliable airspeeds
RE: Hyperveloce (#3969 p.199)
Is it mandatory for the manufacturers that their planes have a functionnal stall/overspeed alarms in all circumstances ?
Systems whose functioning is required by the applicable regulations are subject to a safety analysis during the certification process. (See for example FAR 25.1309). The general principle is that there must be an acceptable relation between the calculated probability that a certain failure occurs and the effect of that failure on the safe continuation of flight.
