GS is a pretty foolproof way of avoiding calamity in serious confusing UAS situations with multiple distractions.
So is applying the memory items and/or NNCs laid down by the manufacturer.
If AF447 had maintained 450 kts and not changed pitch and power we wouldn’t be having the tenth anniversary this week of 300+ deaths.
If AF447 had simply not changed pitch or power, with no reference to GS at all, the same would still be true.
It’s quite true that GS has its uses - the ‘Reference GS’ we used to use on approach in Boeings, and the similar GS Mini in the Airbus are good examples. But I don’t agree that GS is the infallible all-purpose solution you seem to believe it is, nor can you justify using it instead of the manufacturer’s procedures.
While the two major errors you’ve made so far in your justifications can be dismissed as mere typos or because it was late or something, the fact is you still made them, at zero kts, 1 G, and without the pressure of “sudden chaotic UAS + SHAKER + MULTIPLE WARNING”. It’s not really a great advertisement for what you’re trying to sell.
