Is Boeing too conservative in selecting the lower figure of 80 knots compared to 100 knots of Airbus?
80 knots has been proven as as effective A/S by Boeing (and MDC products) for an efficent A/S for cross check. I do not see this as a conservative limit as 80 kts is plenty of pitot pressure. If a pitot tube is clogged by degridation or outside influences such as a muddober nest it would certainly show prior to 80 kts.
Seems to me that airbus loves to sell their products closer to their limitations to make the ignorant number crunchers that rule the skies happy.
