This side of your computer simply consists of a rotating disk with numbers on the middle scale, which when set against similar numbers on the fixed portion (outer scale), allows you to solve problems of time, speed, and distance, calculate fuel consumption, and make conversions between measurements such as statute and nautical miles. The inner scale on the rotating disk is graduated in hours. The slide rule side also has “windows” that you will use to solve airspeed and altitude problems. You can see that the number 60 on the rotating disk is marked differently than the other numbers. That is because most of your problems will be concerned with time —“something” per hour, either miles or gallons. Before you get to that, you should learn how to read and interpret the numbers on both portions of the slide rule side. Rotate the disk until all of the numbers on the middle scale match up with the numbers on the outer scale —10 will be at the top. However, that number “10” may be read as “.1,” “1,” “100,” or “1,000”depending upon the context of the problem. For now, read it as 10. The next number to the right is 11, so each life (or mark) of calibration between the two numbers is equal to .1, and you would read them as 10.1, 10.2, 10.3, etc. If you were solving a problem involving 1,000 pounds of fuel, the number 10 would be read as 1,000, and each calibration would be equal to 10 pounds, and the 11 would be read as 1,100 pounds. SeeFigure 1. Now look at the number 15 on the disk. Between 15 and 16 each calibration mark is equal to .2 and would be read as 15.2, 15.4, etc. If you were solving a problem with an airspeed of 150 knots, the first calibration past 15 (150 in this case) would be 152. The spacing changes again at the number 30, where each calibration becomes .5, and at 60, where each calibration equals 1. Before you read a value from the disks, be sure you understand what each line of calibration is equal to. Now look at the number 15 on the disk. Between 15 and 16 each calibration mark is equal to .2 and would be read as 15.2, 15.4, etc. If you were solving a problem with an airspeed of 150 knots, the first calibration past 15 (150 in this case) would be 152. The spacing changes again at the number 30, where each calibration becomes .5, and at 60, where each calibration equals 1. Before you read a value from the disks, be sure you understand what each line of calibration is equal to. 1. Now set the number 60 (the rate arrow) directly opposite to (or, “lined-up” with) 12 on the outer disk (seeFigure 2). Notice that all of the numbers on the outer disk are exactly twice the value of the numbers on the inner disk: 90 is opposite of 180, 15 is opposite of 30, 3.5 is opposite of 7.0. You will use these ratios in solving time-speed-distance and fuel consumption problems. Look at the inside scale on the disk, where the lines of calibration look like clock times: 9:00, 6:00, etc.—these express hours. The inner scale is in hours and the middle scale is in minutes. 1:10 is directly below 70; one hour and ten minutes is the same as seventy minutes. 5:00 is printed below 300 minutes, and five hours is the same as 300 minutes. To convert minutes to seconds, place the rate arrow opposite to the minutes on the outer scale and read seconds opposite to the “seconds” arrow, just to the right of 35 on the inner scale. Time, Speed, and Distance Problems Time, Speed, and Distance Problems lem, the rate is part of the answer you are looking for. To find the Time En Route, let’s assume you know your airspeed is 150 knots (nautical miles per hour). 1. Set the rate arrow to 150. SeeFigure 3. 2. You have determined the distance to your destination to be 245 nautical miles. Speed and distance are always on the outer scale; 245 is halfway between 24 and 25. 3. Look directly opposite to that value on the inner scale to find th...
