CONF iture
where is it that quote from Sully :
"I choose to start the APU to remain in Norma law" ?
Now that I provided NTSB statement in this regard how about you providing Sully's statement, not your opinion about
Sully did not start the APU to remain in normal law, but to secure some redundancy for electric and hydraulic, and have a chance to achieve an engine restart.?
I suggest you read about G-YMMM B777 London crash.The last moments of Hudson landing are very similar to this B777 crash where ice crystals restricted thrust in last 500ft of the approach. There speed dropped to stretch the glide. As the B777 reached the stall warning speed when the pilot pushed the control forward it landed short at VS of 1400ft/mt. As compared to this at Hudson airbus touched down at 750ft/mt. because the normal law alpha prot prevented further drop in speed as would have happened in direct law.
