stall warning
The ancient Greek.
The stall warning discontinued when the speed was BELOW 60 Kts. How in blazes do you fly a large jet at 35000 ft at a speed of 60 Kts ?? At that height the speed has to be above 270 Kts. The stall warning is of no use to the pilot below 60 Kts when your plane should be at 272 Kts IAS at 35,000 ft, and 0.80 mach speed. The normal speed was 0.82 M and they slowed to 0.80 because of the turbulence. Flying into CBs close to the "coffin corner" is nuts. Remember too that the 'plane rose to 38,000 ft which meant they had no room for error.
