It is somewhat ironic that in this thread “Computers in the cockpit and safety of aviation” where the general tenor is that computers are contributing to current safety problems, that it is suggested that more computation is required (GPS # 104).
Perhaps apart from a very few (extremely rare) incidents involving multiple system failure, where either detection of preceding errors or recognition of previous incidents should have prevented the occurrence, there should be no need for further computational additions.
Why attempt to use GPS with a total speed failure when there are perfectly adequate procedures (Pitch / Power) to temporarily cope with situation until a more suitable solution can be found.
What happens to rule 1 – fly the aircraft, while you fumble with the GPS, switch to speed mode, etc, etc. This ‘computer’ is just as likely to be distracting as the failure.
No, no more computers; just fly the aircraft, deal with the situation and control the human tendency to generate fear from the latest, loudest, brightest failure by understanding the basis of certification, the availability of systems backups, and procedures required to manage these.
But foremost remember manage ‘yourself’, minimise surprise / stress, and fly the aircraft not the computer.
