Default Thanks!

This is really amazing! My RV-4 is in the shop and should finally be done when I get back stateside and this has been some great study material. I am feeling more confident about my GK and expectations of the plane for when I finally take it up for the first time! I just wanted to say thanks for putting this stuff together and posting it!

Hello Mike (Vac)! Your work here is outstanding. This perspective brings a very high level process to the home-built flight training community that has flexibility to be de-tuned or adapted easily when needed. The key here: The instructor to student interface is the part that matters "to the end user". I know it can be hard to visualize that part just by reading an instructor syllabus. Recreationally motivated but professionally minded pilots (the kind that tend to like to fly RV's) do not have to viscerally understand the "behind the curtain" ways and means of a program like this to benefit from it greatly. With the help of good instructors, a quality product can be consistently provided with, I suspect, excellent quality control and quantifiable results, using your courseware. This is the secret sauce of any good community based organization like the Bonanza Society, etc.

I downloaded these programs and I'll keep a hard copy of this great work handy for BFR's, training hops, etc. Thank you so much for sharing your great work, put nicely into a tidy, organized format!

Default AOA Training Resources

Hi Folks!

In an effort to build academics for our angle of attack project web site, I've put together four short essays that describe the basics of the AOA tone, how to use those references for takeoff and landing, basic energy management considerations and how to use the AOA logic when the engine quits. Since the transition training manual references ONSPEED AOA and L/Dmax when appropriate, I thought I would offer these essays as an additional resource for folks that are interested in learning more about angle of attack and how to apply that during everyday flying. Even if you don't have an AOA system in your airplane, the tone allows you to follow along in the videos if you are interested in learning more about the concepts. If you do have a calibrated AOA system and have accurate displays for ONSPEED and L/Dmax, then the material might offer some insight into how to apply those two key AOAs during some of your flying.

The essays are in pdf format for display on any device and they have imbedded hyperlinks, including video demonstrations.

What is ONSPEED? A description of the ONSPEED concept:

Takeoff and Landing Using AOA References. When we land a fighter, we use AOA as the primary reference for energy management during approach and landing. This is how that concept translates to an RV:

Introduction to Energy Management. An overview of energy management and how AOA dovetails with that topic when operating in certain parts of the flight envelope:

Using AOA When the Engine Quits. A power-off glide is a great way to learn about energy management, and accurate AOA displays (or tones) can be useful maintaining aircraft control when you have a power loss:

As always, I'm looking for suggestions on how to improve or correct any of the training resources, including this material. If you have any ideas, suggestions (particularly on how to improve the videos or the articles) or questions, please drop a line or post!

Fly Safe,


Edited: Ouch, just realized (30 April) that one of the diagrams in the last paper was incorrect (the ONSPEED "push/pull" model)! No excuse. Diagram is corrected and original link replaced with link to corrected document. Also, over time there will be corrections and edits made to the associated documents. I'll update linked pdf files as that occurs. 15 May 19 Note: found error with emergency turn back discussion in "unload for control" essay, corrected diagram and verbiage. 24 May 19 Note: Small grammatical corrections to all documents. Revised Fig 8 and emergency return after takeoff discussion in "Unload for Control" essay. Updated links to current versions.

31 May 19: Revised emergency turn-back after takeoff discussion in "Unload for Control" article based on flight test. Flight test video is available here for those interested in learning more about using AOA to assist with EM for emergency turn-back: Note that minimum turn back altitude is aircraft and condition dependent; and parameters in the video are only applicable for the airplane utilized for test under test conditions.

3 Jun 19: Revised "What is ONSPEED" essay.

23 Jun 19: Revised energy management and using AOA when the engine fails essays. Repaired link.

2 Sept 19: Add link to five minute briefing for turn-back test/demo:

Default Stall Spin in the Base Turn Video

Recently there was some excellent discussion regarding slipping RV's that evolved into discussion about stalling while slipping. As a result of participating in that thread, I thought it might be helpful to put together a short video demonstration of slipping and skidding "departures" (the airplane doing something I don't want it to do) in the base turn:

The demonstrations in the video illustrate the discussion in the training manual in the Handling Characteristics section pp. 342-333 and Confidence Maneuvers section pp. 390-391.

Standard notes/warnings/cautions apply: For the demo, the airplane is loaded within Van's aerobatic weight and CG limits for the RV-4. Also, as stipulated in the manual, the RV-4 experiences fairly significant horizontal stabilizer buffet during a skidding departure.

Fly safe,

Mike Vaccaro

Default Comprehensive and Valuable Resource!

Thanks to VAC for all of this hard work!

Here is a document with outstanding structure and content. Any flight instructor considering transition training could very well get whatever they need from this one source for syllabus structure.

Having had written my own syllabus for a LODA application I appreciate everything that this document has. Even the Motherhood issues such as ADM, RM, SRM are properly embedded throughout.

The inclusion of solid AoA flying skills then sets this method head and shoulders above standard approaches to energy management.

Vac's willingness to let all of us copy and use this material as our own is invaluable. This is intellectual property that is actually worth something.

Thanks Vac!
