Well, once again, I have to admit that you are correct. Let's see now: The runway in use at my destination is runway 25. We have just had a cold front pass through, the wind is out of the northwest, 310 at 28 kts gusting to 36. According to the POH (Pilot's Operating Handbook, the official manufacturer's publication for this aircraft), the maximum demonstrated crosswind component for this airplane is 17 kts. Ok, with a 60 degree difference, what is the crosswind component of that surface wind? Does it exceed 17? Should I think about using another airport, about ten miles away, where runway 30 is in use? No need for trigonometry nor vector algebra to answer that question. Jimmy "The Expert" 123x assures me that I can solve the problem with simple division. Let's see now, what number gazinta which other number? Damn, I hate simple division. I just can't figure this shit out. I wish the FAA study guides for the Commercial Pilot Certificate and Flight Instructor Certificate (both of which I have held for more than fifty years), had addressed this type of problem, instead of making me rely on Jimmy's assurance that simple division would give me the answer. Now what am I going to tell me students? Disregard everything in the books. Don't worry about sines, cosines, or any of that trigonometry shit. Just listen to your Uncle Jimmy and use simple division. You'll be fine. הרחפת שלי מלאה בצלופחים | |||

| Thank you Very little  |
Its all about the rudder authority, when you lose rudder authority, you've reached the maximum crosswind the aircraft can handle if it's not enough, go to the other airport...  | |||

Pretty much true, but for low experience trainees, I would rather have them do the maff and make the decision before trying it. Experience is a good teacher, but if you're too new at the game, as primary students tend to be, you might not survive the experience without running afoul of the two rules of flying:

Perhaps you should go back to your High School English teacher and ask her or him what the definition of MOST is. See #2. (not sure anyone can help you with the reading comprehension, you're beyond help there. Wouldn't a pilot be a specialized field, you know, since you need extensive training, multiple tests, flying with an instructor and all.) 1 : greatest in quantity, extent, or degree the most ability 2 : the majority of | |||

Jimmy, I'd tend to disagree with you, at least about algebra. Granted, it does tend to be limited to "technical" fields but that would include engineers, chemists, nurses, doctors, accountants, analysts, anyone doing a cost estimate, most financial trades, etc. How many millions of people does it take before it isn't a special field? Trig is a bit harder to spot in everyday life, but I can assure you that many types of "curve fit" data and information was based on logarithmic principles. Much of what makes a computer chip work to do math is fundamentally logarithmic. Ken | |||

Even a dumb electrician like me needs to know algebra. Here's the cheat sheet to make it easy for you guys.  PS This is just first year student stuff, it gets to be more fun when calculating for wire sizes with voltage drop or parallel/series resistance. Jesse Sic Semper Tyrannis | |||

Hell im a concrete foreman and I use algebra and geometry on a daily basis. Calculus even some days. Knowing math is important. | |||

I want you guys to stop this shit. Right. Now! Jimmy has informed us that all we need is simple division. Stop trying to tell us that we need anything more than that. Skins: Here's something that I learned in missile school in the Navy, 1956. It might help you if you have trouble with simple division: "Twinkle, twinkle, little star. Power equals I squared R. If it's voltage that you need, Drop the square to do the deed." הרחפת שלי מלאה בצלופחים | |||

That's awesome V-Tail There is a simple math problem I've always had trouble with..... If it's a penny for your thoughts but you always put your two cents in where does the other penny go? Somebody is ripping me off..... I have the heart of a lion.......and a lifetime ban from the Toronto Zoo.- Unknown | |||

No one does long hand division in their head without the aid of paper and pencil. Maybe simple addition and subtraction. Common core it designed to train students to perform the calculations in their head. I can do common core in my head without aid materials or a calculator.  He who fights with monsters might take care lest he thereby become a monster. | |||

Well, you are close. Common Core was designed to dumb down the children to a point that in the future they would not be able to run anything let alone a country. I read somewhere that it was first tried in an Eastern Block country as an experiment by the Communists and that country threw the program out. The National Education Ass. Is so damm liberal ( Socialistic ) they have destroyed the school system in this country. I still have kids in school & I would eat Ramen noodles three time a day so they could go to a private school! | |||

Not really a problem, SC. We have been informed by a reliable source that most of us do not need math, anyway. הרחפת שלי מלאה בצלופחים | |||

Do you even know what Algebra is? Hint; it is using known variables and fixed numbers to come up with unknown numbers. Stuff most of us use in everyday life. Banking and finances. Working with proportions, cooking, retail, etc. Shopping. Algebra is key in problem solving. Everyday shit.

I know that I have posted this in the past, but it seems apropos here. I run a small business. I had to run an errand, stop by the bank, etc. It was approaching lunch time so I stopped at a fast food place to pick up lunch for the crew. They had chicken strips on the menu. I figured that about ten would be good, so when I got to the front of the line I asked for ten chicken strips. The young girl at the register pointed up at the menu and informed me that they don't have boxes of ten, they only come in four or six. In my best math tutor voice, I said "If Freddie had four chicken strips, and Suzy had six chicken strips, how many chicken strips would they have altogether?" The register girl stared at me for a few seconds, then started crying. The manager rushed over to see what was wrong. I could not make any words come out of my mouth (yes, believe it or not, V-Tail was actually speechless). The guy in line behind me, trying very hard not to laugh, told the manager what had transpired. Manager told the girl to take a break, pull herself together, took over her position at the register, gave me ten chicken strips, refused payment, and said "This is what HR sends to me, and they expect me to run this #$%^&* store with this kind of help. HR needs to come here and observe for an hour or two, and get a notion of what goes on in the real world." Like the Wise Monkey said, "Maff. Ain't nobody needs that shit." הרחפת שלי מלאה בצלופחים | |||

I can't find it at the moment, but there's a facepalm meme out there where a guy starts to say something 2 or 3 times and then just gives up and goes full facepalm. That would've been my reaction. Be careful when following the masses. Sometimes the M is silent. | |||
