https://www.ntsb.gov/investigations/...ts/AAR0404.pdf is the NTSB AA 587 report. Pages 72-93, 121-149, 153-156 and 159-160 cover the AAMP training and recommendations. Segments from the training material is included with several references to rudder input along with "smoothly." Memory is a funny thing - page 72 says the Safety Board reviewed rudder inputs in the VMS in August 2002. I recall being told about watching those simulations by an observer. I thought it had occurred back in December 2001/January 2002. Either there were two VMS exercises or I spoke with the individual after the August 2002 tests.
