Mother of god, a 1-9g landing.......printer must have been spewing its guts out after that. That's an almighty wallop.
My memory of the 321 was it was a curse when heavy. Trying to select flap 1 in gusty weather and heavy with a green dot of 221 kts and close to the limit speed..... Also remember crap roll control.
Flying by numbers will eventually end in tears and chopping the power early on a heavy 321 will definitely. As per previous I used a flat flare, sometimes I chopped the power right down to the šeck with loads of retard retard stuff and I never flew plus 5....plus 7 ish for me.
