Another point to consider is the considerable increase in drag that occurs in a real fan stop
You're not wrong there. I remember my Complex endorsement training, practicing glides. Trim for best glide and we were still coming down at 1500'per minute. The instructor pulled the prop and we settled out at 500 or so 'per minute.
Its also worth remembering this if practicing glide approaches. I know of an incident, student and instructor glide approach in an Arrow. Prop was back, gliding in just nicely until the pre-landing check on short final of 'prop forward'. The aircraft landed so heavily that it nearly poked the wheels through the wing...the topside of the wing had two upward dents in it and had to be taken off for repair at great cost. Still, says something about the landing gear doesn't it
