What is the aeronautical slide rule?
A flight slide rule, also known as a flight computer or E6B, is a specialized tool used by pilots and navigators for quick calculations related to flight planning and navigation. The slide rule was universally used for nearly 400 years and was the most commonly used calculation tool in science and engineering until it was replaced by the pocket calculator.In its simplest form, the slide rule adds and subtracts lengths in order to calculate a total distance. But slide rules can also handle multiplication and division, find square roots, and do other sophisticated calculations.Slide rules are still commonly used in aviation, particularly for smaller planes. They are being replaced only by integrated, special purpose and expensive flight computers, and not general-purpose calculators.A slide rule is a hand-operated mechanical calculator consisting of slidable rulers for conducting mathematical operations such as multiplication, division, exponents, roots, logarithms, and trigonometry. It is one of the simplest analog computers.The principle behind a slide rule is straightforward. Two bars, each marked with scales, slide next to each other. Aligning numbers on different kinds of scales allows different calculations, such as multiplication or trigonometry. Accuracy, however, is limited and depends on the user’s skill.
What are 5 uses of slide rule?
Slide rules can be used for multiplication and division, squares, cubes, square roots, cubes roots, trig functions, and exponentials and logarithms. For purposes of the 49er’s slide rule competition, you only need to know how to use the slide rule to do multiplication, division, and square and cube roots. As mentioned before, the slide rule is a calculator. By using various scales, a sliding central piece, and a cursor (the outermost sliding piece with a vertical red line), the user can multiply, divide, find cubes, cube roots, squares, square roots, sines, cosines, tangents, reciprocals, logarithms and exponents!The slide rule was universally used for nearly 400 years and was the most commonly used calculation tool in science and engineering until it was replaced by the pocket calculator.They focused mainly on the property of logarithms (that log x + log y = log xy) and how it could be exploited to perform multiplication and other calculations on a slide rule. This is understandable as most slide rules have logarithmic scales.Simple slide rules will have a C and D scale for multiplication and division, most likely an A and B for squares and square roots, and possibly CI and K for reciprocals and cubes. In the early days of slide rules few scales were provided and no labelling was necessary.To do a calculation with a slide rule you reduce all numbers to scientific notation with 2-4 digits then use the slide rule to perform the basic operations. In a separate calculation you find the order of magnitude by combining the powers of 10. It is up to the operator to determine if the result makes sense or not.
What is the 10 slide rule?
The guidelines for this rule are as follows: No more than 10 slides. No longer than 20 minutes. No larger than 30-point font. The 7×7 rule in PowerPoint is a guideline designed to create clear and effective presentations. It suggests that each slide should have no more than seven lines of text, with each line containing no more than seven words. This rule aims to keep slides concise and easy to understand.The idea of the 10/20/30 rule is easy to understand, which is summed up in three points. Your presentation should consist of no more than 10 slides. Your presentation should last no longer than 20 minutes. The text on each slide should be no lower than 30 points in size.The 7×7 rule in PowerPoint implies that you should use a maximum of 7 lines per slide, with no more than 7 words in each line, and a total of 7 slides per presentation. This can be done in bullet points to simplify the slide.Today I want to discuss the 1-6-6 Rule. Quite simply, this “rule” says that each PowerPoint slide should have one main idea, a maximum of six bullet points, and a maximum of six words per bullet point.The 5/5/5 Rule explains what it is right in the name: when creating slides for your presentation, use at most: 5 words on a single line.
What is the 7 lines per slide rule?
What is the 7×7 Rule for PowerPoint? The 7×7 Rule says that, for each slide in your presentation, you should use no more than: 7 lines (or bullets) per slide. The idea of the 10/20/30 rule is easy to understand, which is summed up in three points. Your presentation should consist of no more than 10 slides. Your presentation should last no longer than 20 minutes. The text on each slide should be no lower than 30 points in size.If you are presenting to an audience, keep the text on slides to a minimum. Consider employing the “5-5-5 rule. No more than 5 lines, no more than 5 words, no more than 5 minutes. Think short and sharp memory joggers instead of rambling paragraphs.The idea of the 10/20/30 rule is easy to understand, which is summed up in three points. Your presentation should consist of no more than 10 slides. Your presentation should last no longer than 20 minutes. The text on each slide should be no lower than 30 points in size.The guidelines for this rule are as follows: No more than 10 slides. No longer than 20 minutes. No larger than 30-point font.To keep your audience from feeling overwhelmed, you should keep the text on each slide short and to the point. Some experts suggest using the 5/5/5 rule: no more than five words per line of text, five lines of text per slide, or five text-heavy slides in a row.
