Needs Fixing: NAR L2 test questions

I was just reviewing the NAR L2 test pool, in preparation for giving the test to a NIRA member. It's been a long time since I've looked at the
questions. I was surprised to find several wrong answers, and several answers are now incorrect as a result of the recent safety code changes.
I've forwarded the list of corrections to Carl Tulanko, but here they are in case any one else is giving or taking the test:
A15) There are HPR motors with less than 160NS total impulse. The G33 and G75 are current examples, in the past the F101 and G125 were others. A motor can be HPR because it's over 160NS, because it's over 62.5g propellant, or because it's over 80N Tave.
A23) same issue as A15
C3) Answer C is no longer true as a result of the recent changes. The answer depends on the motor size being flown, and is now the same as the safe distance: 100' for an H, etc.
C4) same issue
C9) Technically correct, but bad question. The reality is you redefine your field to be that part of the field that does not include the house, then launch at least 1500' from the house.
C21) Aliphatic resin based glues (yellow glue) is just as good or better than epoxy if the materials are paper and wood. They are MUCH better than 5 minute epoxy.
C22) Same as C21. 5 minute epoxy weakens with heat about as much as hot melt glue does.

Doesn't look like they've bothered to update the certification process to call out 'active recovery' either.
Guess that's another launch we get to pass some saucer flights.

The TRA test is also out of date, BTW.
Some of the error are due to changes in 1127, some due to changes in the safety code, and some due to the current legal battle (what, 6-7 years now?)
The tests could be changed based on what happened in the last 3-6 months, but that means they'd keep changing. Maybe the best thing to do is to wait for things to settle down on all fronts...

That makes no sense. Why teach people incorrect information? It's akin to continuing to teach our children that Pluto is a planet simply because the text books haven't been updated. If you test them on the subject and score it as per the test answer grid, they are incorrect, and if they put down the correct answer, they are still incorrect.

I suppose that because a "select group" decides that Pluto is no longer a planet and you buy in to that, that you also buy in to the "revised" history our former President and company spewed out and got into some history books?
The next meeting should return Pluto as it has its own sattelites and that is one of "their" own definitions for a planet. When a select group decides to purposely run a meeting till the wee hours to push through a vote with a stacked deck, why should we accept that vote as Gospel?

Do you still call Ceres, Vesta, Juno and Pallas planets? When they were first discovered, they were thought of that way... until it was discovered that they were part of an entire group of objects in that orbital zone. Pluto is similar in that respect now.
*WHY* does the age of a decision seem to enhance its' credibility??? :-)

Ceres and the others DO NOT have their own satelilites. So they do not fit the definition that was decided on by this same group. If Ceres was to be a 'planet' then Deimos, Phobos, Ganymede and all the other 'moons would have to be named as planets also. Pluto is approximately 1/4 larger than Mercury, yet it has been demoted on a whim by a "select group". Mars is only 240 more miles in diameter than Pluto, so logically if both Mercury and Mars are still planets then whu not Pluto? Mercury does not have a natural satelite, Mars has two, Pluto three, again the whim of a few changes all.

Additionally Ganymeade, (moon of Jupiter) and Titan (moon of Saturn) are both larger than Mercury, but as they are "Satelites" of another they do not qualify as planets. Pluto is not a 'satelite' of another, its origin is still hotly debated, it has its own 'satelites', and a stable but somewhat eccentric orbit. So why is one a planet and Pluto not? Because a select group pushed through 'their' definition of "is". Yes Mr. Clinton just because you and your cronies say it does not change what actually happened. Nor does a decision made in the wee hours make it so. I am confident the next "meeting" of these minds shall rectify the situation, but after how many changes to textbooks and $$$$$$ spent by schools to acquire the new "correct" definitions.

Frankly, anyone who has their facts this badly screwed up (I'd suggest you recheck the size of pluto, mars, and mercury...) shouldn't be commenting on this. ;)
You also clearly havn't even read the definition.

Equitorial diameters, Pluto 6400 km/ 3980 miles, Mars 6790 km/4220 miles, Mercury 4850 km/ 3015 miles. And as to reading the definition, which one? The final one voted in? The one that would have made Ceres and Charon (a moon of Pluto) each planets? Even the people that are deciding this haven't finished the argument of "the" definition yet.

Better double check your sources. Pluto is a bit under 2400km diameter. Half the size of mercury, about a third the size of Mars.
We just visited the Lowell Observatory outside Flagstaff where Pluto was discovered, just before it was delisted as a planet.

Bob data was straight from my college textbook. Now if that should be in error then a whole bunch of students were misinformed. Not saying the book is right or wrong, just commenting in that data from history to the planets and beyond is probably in error somewhere. Isn't that correct Mr. Clinton?

It was wrong, textbooks are often wrong.
And whats with the constant Clinton bashing? Can't you say anything else? You sound like Min.

And when were you in college? I wonder what my 1960s copy of Halliday and Resnick has for the size of Pluto? We've got better data now than we had when I was a kid. For that matter, how many moons does it say Jupiter and Saturn have?

A couple years ago my daughter brought home a booklet that was for her "history" class. It was short biographies on various people. It had 3 pages on Apollo-11 and Niel Armstrong. IIRC I found about 8 errors in those 3 pages. My wife, who teaches humanities at the local community college, found even more in the Marco Polo article.
Last fall she went to a convention outside Boston. While there, she bought the book written by one of the presenters: "Lies My Teacher Told Me: Everything Your American History Textbook Got Wrong" by James W. Loewen. It's no wonder our schools are turning out clueless graduates. Like that IDtenT from Yale that's running this country.

Was one of the lies that the President runs the country? When I took Government I learned that the executive branch implemented and enforced the laws that Congress passed. That Congress could use the power of the purses strings to stop any policy it did not approve of. And that the Judiciary branch interprets, not creates, laws and policy. In college I learned that it takes 4-6 years for the influence of a President to become evident (of course that was 2 years into the Reagan administration taught by a professor tended to smile when she said "socialist" and gag when she said "conservative").
Of course the modern reality is that Congress has completely abdicated their role in government. They allow the President and the Courts to have far more power than the Constitution intended and then complain when it happens. If they would just learn to say "no" once in a while...
Now if our schools only taught from "The Politically Incorrect Guide to American History" (google it) I wonder what things would be like?

Bob, do you still have that textbook? I wonder if those two volumes are still in use for freshman physics? Dr. Halliday was my academic advisor at Pitt in the 1970s; a fine gentleman and a great teacher.
