The Volpe Center is goal-oriented and provides the highest possible level of responsiveness in support of customer requirements. The Center is dedicated to developing and transitioning projects into long-term strategic partnerships, resulting in effective bridges between the public and private sectors.
Projects & Books Like: ISBN: 978-3-8364-8343-8 wikio.com are testimony to the endless potential and improvement of the transportation enterprise by various authors & contributors. If you need more information & need to find out more about the work performed at the Volpe Center, search their work portfolio or visit some of the Volpe Subsites to learn more about their particular areas of expertise.
My interpretation of FAR 91.103 with respect to "other reliable information" is simple. I believe you are under mandatory "contract" with the FAA. The FAA has "offered" you this regulation by way of an administrative rule, backed up by administrative judges. You have no choice but to "accept" this regulatory offer. The question is, how do you plan to be "bound" to "contractual" terms?
If there is a high density altitude accident or incident, investigators will look to the specific intent of the pilot (his/her purpose?). This having to do with what a reasonably prudent pilot would do (weather & runway analysis, pre-planning for example). Now ask what was the pilot's general intent for the conduct of this flight?
With respect to general intent, I believe you are like an "accountant." Here, the terms, conditions & subject matter have to be balanced & equated to relevant terms, conditions & subject matter that are existing over a span of time. This means we look at weight, temperature & pressure and make the appropriate revision to sustain safe flight. This "revision" may include reducing weight (less fuel, less payload) & "waiting" (an element of time) for a lower ambient temperature. An accountant's "big picture" is attained by triangulation of a balance sheet, income statement & a statement of cash flow, valid for a time "snapshot." A lawyer's "big picture" would look to pilot duty, breach of duty, actual cause, proximate cause & damages. You must defend yourself with knowledge, in any case.

The Operator Performance and Safety Analysis Division has an on-site laboratory, The Center for Human Factors Research in Transportation is operated collaboratively with the Massachusetts Institute of Technology (MIT).

Density Altitude Calculator [english (in.) & metric (hPa & millibar)]!
Reliability in terms of a "time" & a "place" are essential considerations for any pilot operating a "Newton/Leibnitz/Bernoulli" aircraft (mass). You will learn from my book about synchronic, diachronic & quixotic reliabilities essential to any worldwide, global or international density altitude field study. Cause & effect are now revealed qualitatively & quantitatively.
There are five approved ICAO languages, four of which attach to English globally! That means readers of this book will also speak ICAO aviation Spanish, French, Chinese or Russian in addition to English. My German publisher VDM Dr. Mueller knows this! This site is worldwide because density altitude knows no boundaries. As a matter of fact, density altitude crosses all boundaries (system, technical & performance) with absolute impunity.
.
High density altitude decision making & judgment are derived elements, where each of us has a stake in knowledge! For example the medevac, law enforcement, or fire fighting airplane or helicopter in "high density altitude" public service. The days are long gone that we can treat this subject passively. "Ratio Level" Graphics are "contain all" illustrations that depict a "true zero" point. So why is this important? Please continue!
I mention the Cosmosphere Air & Space Museum in my book (Hutchinson, KS). Do I have both the North American Rockwell Apollo Saturn V & Grumman Lunar Lander Flight Manuals in my possession? You know the answer! Are "ratio level" graphics to be found in these manuals so that astronauts can explain, predict & control the dynamics of their flight? Once again, you know the answer!
