The rotorcraft manual was written by a Jeppesen tech writer, Dan Mowrey. Dan was conscientious but I doubt if he’d ever previously seen a gyro; however, he reached out to the gyro community for assistance and Dr. Bill Clem, a Dominator pilot who lived nearby, responded by almost camping out in Dan’s office during the manual’s preparation.
Jeppesen’s mandate from the FAA was “don’t offend anyone” which caused them not to address incorrect thrustlines.
I participated in several conference calls with Dan and others but thrustline was a taboo subject as a result of RAF Canada’s input.
