Do these unreliable airspeeds sims sound different stall (false) alarms at one point ? Do these sims implement "surprises" (different sequences of failures of the Pitots, static ports, whatever) or are they scenarii known in advance and prepared beforehand ?
1. Simulation of Stall Alarms are always to be considerd as "true" (reliable AOA Probe)
2. More or less the scenario is based on "surprises".
