Micro,

Aerocat et al. Alternative action for alerts might be plausible, but any situation where the alert or warning questions your judgement does not warrant further use of judgement.

A favourite reference Celebrating TAWS ‘Saves’: But lessons still to be learnt.
Note all of the incidents, but particularly # 7, re the crew’s judgement of flying level or re-establishing a safe approach path.

framer, I recall a simulator trial at an operators conference where pilots were expecting a Pull Up warning; the purpose was to evaluate differences in procedure application and timing. The scenario was at min effective timing for the equipment – no pre alerting (yes it can happen, see incident #8)
Half of the pilots did not survive the encounter. The deviance was divided equally between a late/slow reaction or less attitude/speed trade than required/available.
