Version 2.7 Avialable
Version 2.7 Summary of Changes
Overall, this version primarily continues to tweak Vne discussion. If you’ve looked at the previous couple of editions, you can see how this has evolved over the past couple of months. I hope there is now zero.zero ambiguity regarding this very small end of the airspeed band as it applies to RV-types for the purpose of familiarization and training: only exceed Vno with caution, treat Vne as TAS at all altitudes, and do not exceed Vne under any circumstances. There are some other minor changes for readability and a few hyperlinks have been added or corrected.
Special shout-out to Kevin Horton and my buddy Dave Evans for (patiently) helping properly edit the discussion and keeping me coloring inside the lines.

Changes/additions are in red font, and deletions are not tracked.
1. Modified Aerodynamics Briefing, corrected/modified bullet briefing points, replaced Vne diagram/figure. Added Vne look-up tables for 210 MPH limit airplanes (RV-4/6/9) and 230 MPH limit airplanes (RV-7/8): Corrected CAS math in Table 2-1 and added Table 2-2.
2. Added note to Table 2-3 (RV-4 Aerodynamic G-Available at 1375 Lbs Gross Weight)…in that table the red font does not indicate a change, but rather that a G or airspeed exceeds design limits. Table 2-3 is identical to Table 3-8. Same note added to Table 3-8.
3. Revised Figure 3-18 in Vne discussion in Part 3. Edited/revised Vne discussion beginning on page 337.
4. Minor edits/changes to some of the RV-type handling rules on thumb in Appendix C.
After a few thousand hours of typing, research, flight test and validation, driving some very patient folks a bit crazy with questions, less than stellar IT work, and wearing out at least one old lap-top, this program/concept/document is getting reasonably mature; so I don’t anticipate any major changes, although I’ll continue to make corrections and improvements as time permits.
Of note, on 14 Oct the NTSB is hosting a working group that will be looking at ideas for mitigating loss-of-control mishap risk. Certainly one of the best/easiest means to do that is improve the quality of familiarization and training resources available for folks. Hopefully, this project demonstrates what's in the art of the doable and has proven helpful to some folks in our community.
I’ll update the separate tab data/graph/figures document soon.
If anyone has any suggestion as to what would be a useful follow-on project (e.g., video presentations, video maneuver library, power-point briefings, etc. designed for familiarization or instructor use), I’d be happy to correspond via PM, e-mail or post.
As always, if anyone would like a Word version, has any suggestion for improvement or corrections, please drop a line as well.
