Plane Simple Truth
brothke writes "In the TV show House, M.D., a premise that protagonist Dr. Greg House holds dear is that people are liars and stupid. Real life is often not far from House's observation. At the general public level, people are
often misled by their lack of common sense, their deficiency in understanding statistics and basic science, and therefore fall victim to the lies of the myriad
charlatans that claim to have something that fixes everything. A piece I wrote on that issue, New York
News Radio — The voice of bad science, details that.
While it is too broad to call the authors of Fuel efficiency of commercial aircraft: An overview of historical and future trends liars; their mediocre research created the scenario that far too many took their research as
reality. Known as the Peeters report, after lead author P.M. Peeters, the authors of Plane Simple Truth refute the wide-spread belief that the fuel efficiency gains in the commercial aviation sector are erroneous, which is the
principle theme of the Peeters report." Keep reading for the rest of Ben's review.

summary
Valuable book in the important debate over greenhouse gases and aviations contribution to it
The aviation industry is often an
environmental pariah, with environmentalists crying foul at the industry. But it is only a pariah due to flawed
data that negatively influences the public debate, and this book attempts to set the record straight. Plane Simple Truth is an articulate and extremely well-written and researched
rebuttal to the Peeters report, and other flawed studies.
The Peeters report flies in the face of reality, in which gains in jet engine efficiency over the last 40 years have been astounding. Contrast those gains with the popular Cadillac Escalade and similar SUV's whose mileage per gallon is often measured in single digits, and whose efficiencies have gone in the opposite direction.
The authors wrote Plane Simple Truth as they felt that never in recent history has an industry been so maligned and the public so misled by so much falsehood and distortion. With the Peeters report and climate activists pointing the accusing finger at the aviation industry, Plane Simple Truth is their defense.
The reality is that while the Detroit automakers were making huge gas guzzling SUV's well into 2008, companies such as Lockheed had fuel efficiency on their mind back to the 1970's. In fact, fuel efficiency has been a key factor in the aviation industry since the early days. This is based on simple economics and physics in that every pound of fuel, is a pound of payload that the airline cannot carry, which costs the airline money as fuel economy is a major driver in the industry. The bottom line is that fuel economy is absolutely critical in commercial aviation. Witness the number of aviation bankruptcies in 2008 when fuel prices soured.
Like a first-rate defense attorney, the book defends the industry against its charges. In every chapter, the authors show the errors, both intentional and those errors of omission, where incorrect reporting and research have negatively affected public opinion.
While not a book about the history of jet engines; the book details the fascinating and phenomenal improvement into the efficiency of the technology. But the underlying theme of the book is that of the environmental issues.
The book details the fundamental errors in the Peters and other environmental reports that have been often taken as the unquestionable truth. Rather than analyzing the facts like the book authors have done, the media often creates sensationalist headlines with an emphasis on short sound bites, often at the cost of scientific fact. Not only do the authors refute the Peeters report, they show in detail how important aviation is to the global economy. In fact, the aviation industry is critical to every growing economy.
The books 18 chapters cover the entire spectrum of jet emissions and their incredible development in detail. Current topics such as bio fuels and their promise, new engine technology, aerodynamic gains, green airlines and more are discussed. The book makes ample use of charts and photographs to illustrate its points.
Plane Simple Truth is a fascinating book that exposes the myriad errors of the flawed environmental studies. It is also a fascinating look at the development and history of jet engines, and the amazing progress that has come about in the last few decades. Huge strides have been made that increase power by significant amounts, while simultaneously cutting emissions. In fact, there are less environmental issues to worry about in the future due to aviation, given the significant strides that are being made.
The book makes many of its valuable points via the approach of letting charts and diagrams do the talking of often dry statistical facts. Be it fuel efficiency, less emissions, or toxic gases, the book shows that misplaced myths and the smoke and mirror games that are often used by those with an agenda, have negatively affected the public's view of aviation.
We have seen that a single bad piece of research is enough to derail an entire industry and mislead the press and politicians. Plane Simple Truthis an important book that has relevance to everyone, as there is no one that is not positively affected by the aviation industry.
While the industry still has a long way to go in other areas such as passenger satisfactions, lost luggage, air traffic control delays and much more, the engine makers have continually pushed the envelope in terms of fuel efficiency and environmental concerns, and they have done this for well over half a century. This was long before the environment was a cool topic. It was also done when jet fuel was still quite cheap.
While the book's authors are intimately involved in the airline industry and clearly pro-airline, and the book's publisher is Aerospace Technical Publications; the authors let the facts speak for themselves. While greenhouse gases and their potential negative effects are part of the public and scientific debate, the ability of modern jet-engines to minimize those effects is clear. Plane Simple Truth is a valuable book in the important debate over greenhouse gases and aviation's contribution to it.

I guess while putting down the rest of America for being easily led by the nose, the author forgot to read about how to use simple punctuation.
While we're on it, perhaps Barnum was right, but perhaps he was more right in the second less-well-known part of his statement.

Starting your review with a convoluted first paragraph chock-full of double negatives and irrelevant references is a Bad Idea. I had to read it three times before I figured out which book was being reviewed and what the reviewer thought of it.
The review also takes whatever this book says as gospel. How do we know that this book is any more correct than the studies it tries to debunk?
From the review, there seems to be a lot of talk in the book about jet engines (turbofans). But is the subject of propellers and turbopropellers brought upon ? They are usually considered to be the most efficient for speeds around mach 0.6.
Consensus (among psychologists) is that IQ scores are following a normal distribution, thus mean and median are the same.

Can you really have a 28 valve engine? Wouldn't it be 6 cylinders * (2 intake valves + 2 exhaust valves) = 24 valves.
Just askin'...
For a start, they seem to hinge their conclusions on per-seat-kilometer values, and then seem surprised at the outcome - per-seat-kilometer values miss significant aspects of the subject at hand:
:)
1. Cargo - planes carry significant amounts of cargo today, on the piston engined aircraft of yesteryear it was pretty much 'passengers OR cargo, but not at the same time'. Thus the plane today is doing work that your plane of yesterday would be excluded from because you aren't getting a per-seat-kilometer value for it (no seats).
2. Range - planes today carry out some serious routes, with the top end of the scale actually topping out at between 8,000miles on a regular basis (there are longer routes, but they are less common). You won't be getting that in piston engined aircraft.
3. Reliability - jet engines are much more reliable than the piston engines of yesteryear, which is why we now have ETOPS (extended-range twin-engine operational performance standard) hitting 207 minutes. Thats three hours and twenty seven minutes distance from an airfield on one single engine. Try that in a piston engine aircraft of yesteryear.
4. Reliability - yes, its worth mentioning again. Jet engine aircraft can run sectors with minimal turn around, with minimal maintenance between sectors and with minimal top-ups of required fluids. Piston engined aircraft required a lot more in the way of coaxing and looking after on the ground between sectors. More time in maintenance means less time making money.
5. Longevity - there haven't been many piston engine aircraft that were built for two or three decades in passenger service (the DC-3 comes to mind, but not many others). Most piston engine passenger aircraft of the pre-war and immediate post-war period were designed to last only a few thousand hours, or a couple of years in passenger service.
Oh, and yes, I'm related to the aviation industry
Look up the differences in how they came up with the ratings between 1985 and 2008.
You can't just look at the specific numbers and ignore the specs of the tests that brought about those numbers.
Excuse me, but I just actually read that report (...on slashdot!? I must be new here), and it nowhere states that jet engine efficiency *hasn't* improved tremendously over the past 40 years. On the contrary, it shows clear diagrams that shows they *have* improved a lot.
However, it states, probably correctly, that compared to the last-generation *piston* aircraft engines which where built around 1955 or so, first-generation Jet engines used twice as much fuel (per passenger or kg moved per kilometer) compared to those. However, that amount of fuel since halved so they are now about on par with 1955 piston technology. Doesn't look like a lie to me. Of course, modern jet engines can fly a lot faster than those with piston engines.
In addition, it states that the amount of reduction will level off when the technology has matured. This happened for piston engines, and I don't see why it wouldn't for jet engines; most things to improve their efficiency by a lot have already been invented by now. This explains why they use much less fuel than 40 years ago, but doesn't guarantee in any way that they can get a lot more efficient still.
Of course, I like taking a plane to the Hawaiian beaches as much as the next guy, but I don't see why we need to post this kind of bullshit stories just so we can fool ourselves into thinking that planes do not use a lot of fuel.

So, you are comparing your experience with overall running MPG (I assume tank-full to tank-full) against running 100 miles along a freeway at 55mph? Yeah, let's compare apples to oranges -- that will give useful figures.
Instead, why not look at the CAFE requirements, which have shown rather more modest improvements?
Car engines have made huge improvements in efficiency, but much of those gains have been lost by increasing the overall weight of cars. Compare a modern Mini to the weight of the original -- Old: 1,360 lb, New: 2496 lb.
The real "Libtards" are the Libertarians!
If they're so stupid that they're doing eighty, can't tell that the car ahead is going slower and aren't paying attention to boot, it's not ME wasting the fuel.
I'm not going to waste my gasoline to save yours, especially when you obviously don't give a shit about your fuel economy or you'd be going slower.
Free Martian Whores!
Since the CAFE was enacted in 1975, the required fuel economy has gone from 18 mpg (1978) to 27.5 mpg (1990, originally 1985). The standards for light trucks are a little more convoluted (especially in the past), but went from a low of 15.8 mpg to 22.2 mpg (2007).
Congress recently passed an increase in the CAFE to 35 mpg by 2020, an increase of a whole 7.5 mpg in the next 12 years, after nearly 18 years of no increases.
It should also be noted that these numbers are for an average fuel economy across a 'fleet' of vehicles, meaning that they're not for a particular model, but for the cars sold in a particular model year by the particular manufacturer. This means that selling hybrid SUVs gives the manufacturer a boost in the average gas mileage calculation used for the rest of their SUVs and trucks (excepting those that are above the maximum weight for CAFE requirements). They also get a credit towards the calculation for hybrid and multi-fuel vehicles (beyond the increased mpg those vehicles might get).
So, of course a 2008 full-sized Ford pickup gets better gas mileage than a 1975 full-sized Ford pickup of the same model. However, the number is unlikely to have doubled in the 33 year time period. In fact, fueleconomy.gov puts the numbers from 1985 to 2009 at an increase of roughly 3 mpg (why they don't have the numbers going back to 1975 I don't know).

I know I gave numbers for 1985. That was the earliest numbers available from a trusted source. The numbers are not from the EPA MPG tests. These are numbers provided by people who own and use the vehicles, which make the numbers more reliable than the EPA tests.
There is no "-1 offended" or "-1 you don't agree with me" mod options for a reason.
The fact is they didn't make SUVs back then.
Yes, they did. The Chevy Suburban was first built in 1935, and the International Harvester Travelall was built from 1953 to 1975.
Or visit Fuelly.com and just browse what some people are getting for fuel economy. There's a few people out there that apparently can't enter numbers properly, but it's a nice view of what people are getting in reality and not just "EPA Estimates".
Yes, my cars are on there too.

Looking at the tails of the curve, you're always going to have more people at the low end whom are randomly physically screwed up (due to accidents or whatever) and a smaller tail at the high end of superior intellects.
IQ has a normal distribution because IQ is defined to have a normal distribution. If the tail at the high end is too small, then the tests will be adjusted.
Finally! A year of moderation! Ready for 2019?
Well, some SUVs are (usually the larger ones), while the smaller "crossover" vehicles, like the CR-V, Rav4 and Forester, are Unibody constructions. As for trucks, the Honda Ridgeline is built on a Unibody platform.
It must have been something you assimilated. . . .
*ahem*
I beg to differ, SUV's were indeed made prior to 1980.
The label of SUV is of modern origin but the concept of a station wagon on a truck frame that has at least some off-road capability goes back as least as far as WWII. (With or without 4WD)
