UnAnswerd said:I just finished the FAA regulations in ground school, and we're moving on to aspects that deal with aircraft performance. One of the first things we did was cover density altitude, and figure such altitudes given a list of known factors. I completely understand the concepts, and also understand how to figure density altitute. The problem arrose when I needed to divide some numbers, and I said I would need a calculator. My GS instuctor looked at me kind of strange, and said "you can't figure it on paper"? I said that I had completely forgotten how to divide numbers without the use of a calculator. This did not seem to sit well with her. She went on to question me about what I wanted to do with my flying!!! She said that if I ever wanted to fly professionaly, that I should take a basic math course!!! So at this point I feel like a total retard, and all I can do is give some excuse about using calculators since 5th grade...
Now I know that I SHOULD be able to divide numbers on paper, but does anyone think she was just a little over the top? I mean, I was under the impression that you could bring a calculator to the written exam? I really do not see why it is so alarming that I simply cannot divide numbers on paper. I've seen pilots use electronic E6B's, and yet I can't use a $2 calculator?
Would really appreciate some honest advise on this.
bigD said:That slide rule E6B *is* a calculator. It's just an analog one. The only difference between it and an electronic one is the presentation. Well, that and the batteries don't die in the analog one.

It's Algebra I - - in our school district, it's required for High School graduation.RJP said:And Tony, "Quadratic" what? What the **CENSORED****CENSORED****CENSORED****CENSORED** are you talking about man. I can see why you're embarassed but we're probably not thinking of the same reason.
Oh stop!! you're just being "diddicult"!! Hey Mavurerurik....lay off the sauce and get that shift key fixed!!bigD said:Speaking of retards....
I haven't read every post on this thread in detail - I will - but I agree that your ground school instructor could stand a lesson(s) in diplomacy. I would not recommend this, but someone should ask your ground school instructor if she remembers the Law of Recency from the Fundamentals of Instructing.UnAnswerd said:The problem arrose when I needed to divide some numbers, and I said I would need a calculator.

Tony has a point, which could spawn an entire discussion on the inadequacies of American education and the value of a college education for pilots.TonyC said:Perhaps it is a generational phenomenon, or perhaps not. When I went to school we were expected to write legibly, spell correctly, and perform mathematics with pencils, tables, and - - gasp - - even a slide rule in high school. Today my children are not expected to even spell correctly. It sickens me. I was embarrased a few weeks ago to admit to my daughter that I had forgotten the quadratic formula. I would rather die that admit to this forum that I had forgotten how to DIVIDE.
heh heh, imagine my surprise when, after graduating from highschool, i bought a TI-88 graphing calc for over $100, b/c to get a B.S. at my college you have to take calculus, and for the few calc. classes I took we had to do EVERYTHING freehand, no calculators: graphing, functions, the whole 9 yards. Best $100 I ever spent....Whirlwind said:Ditto... 5th grade was the last year calculators wer forbidden, after that we all had them. By high school algebra, they were REQUIRED, we all had TI-35 or TI-36X calculators in class, you got a demerit if you didn't bring yours.
bobbysamd said:I, too, have forgotten the quadratic formula, but I haven't thought about it much since high school - which goes back thirty-five years. Besides, I was never that swift with algebra.
Me too. I can also do long division. And sometimes, on a good day, I can calculate the altitude I need to lose to cross a certain fix. Of course they throw in the X factor (50 miles south of certain fix).TonyC said:I can still factor, though![]()
Used to do this sort of calculation a lot in the ol' 1900D and without a calculator. You could start a nice, slow descent "immediately". The gradient would be 450 ft/NM (9000 ft divided by 20 miles, assuming those are "NM"). The descent rate required would be 900 ft/minute (120 knots being 2 NM per minute and taking 450 ft/NM and multiplying by 2 NM/min).paulsalem said:Your 20 miles out from the airport at 10,000 feet. Field Elevation is 1,000 feet. Your doing 120kts accross the ground (or is the ground doing 120kts under you?) anyway, when do you start your descent. By the way its night time, so you can't see the keys of your calculator, and its solar powered.
See the need for division. And this is just the tip of the iceburg.
