Machinbird;
Thanks, I don't disagree frankly. I'm just trying to find something outside the box to figure out why someone would point an A330 15deg NU and keep it there at FL350+ and these papers got me thinking. I've flown the aircraft at altitude and I must say it was pretty responsive in pitch and roll in Normal Law. I've always doubted the notion that the airplane was slow and 'slushy' to respond to the stick at altitude and that a bit of PIO or inadvertent backstick while controlling roll resulted in an "accidental" climb that continued to 38,000ft but I'm outa ideas!
