Revising Cyclic and Collective
it being a few years since I did the last revision, and some new ideas have popped up, I'm asking for suggestions for the next revision. Plasesend me a pm, and your ideas will be considered.

It's been a while since I read your books Shawn, so I can't remember what there was about performance planning, especially for light pistons since this seems to crop up a lot in accidents along with IIMC.

also been a while since I read the book. Not sure my comments will be applicable
A lot of aerodynamic studies and modeling has moved to quad copters and new concept like the Racer, Raiders,
Also a lot has changed with the cockpit, even low cost (bell 505) get dual garmin and integrated performance calculations and other helicopter-only features in there
Also composite it used to be reserved to a fenestron shell now it is the whole aircraft
Also slanted fenestron of the H160 how does that affect longitudinal stability do you get more noze down on ptich up?
The ethernal question of the pedal work with the fenestron like the Cabri has been discussed a lot
underslung vertical stabilizers seem to be hot these days too
just ideas

As per Crab’s suggestion, an accessible guide to why awareness of performance limitations might help to prevent a lot of R44 accidents. Maybe something along the lines of checking power assurance margins and identifying traps that can be avoided for those who enjoy a good read, but struggle with due flight planning diligence.

Downwash
Shawn
I dont think you talk much about downwash and how it varies with mass/rotor area/height/wind velocity. Info like how fast the downwash will be/where the peaks of speed with be, the shape of the downwash stream tube, formation of vortex, depth of the downwash flow IGE. I've seen some academic papers on it but your take on it would be great.
