Thanks for your reply, CONFiture. Sorry if my question was ill-considered. However, in minute 2:10 speeds became inconsistent, and FCPCs reconfigured to ALT 2 law, therefore low speed stability was operative.
In twelve out of thirteen cases of erroneous airspeed discussed in BEA Interim Report No.2, the airplane switched to alternate law. In one case, this switch was temporary. Nine cases of triggering of the stall warning were observed.
Apparently "low speed stability" was never activated in these events, and I would like to understand in what conditions it would be.
