Member 0 853 posts Gender:Male Location:USA (EC) Report post Posted March 24, 2008 Ever wonder what those "little numbers" on the Breitling Navitimer dial bezel were for, or if you've wondered well-nigh the utility of the Slide Rule and how it can help you in land or in air, then I have synthetic this guide for you. If you're deciding to condone this guide considering your rep Slide Rule is inaccurate, don't ignominy it just yet! I will show you how you can use it for worldwide calculations and other novelty functions that you can proceeds for your wholesomeness when stuff asked by friends and viewers what the full-length does! Don't be embarrassed by not stuff worldly-wise to know the functions of your own watch again! The slide rule on the Navitimer series (and other Breitlings/Sinns that use this full-length [does not include Bentley lines]) is based on the E6B flight computer; a computer not in the sense that it's not electronic, but a tool for pilots to aid in gingerly fuel burn, wind correction, time en route, and other items. In the air, the E6B can be used to summate ground speed as well. Paper version of Slide rule: This is the little nifty vellum of the slide rule that comes with all Navitimers that would help the prospective user to icon out how to use it, which is accompanied by this diagram that is included in the manual: A full-scale version can be downloaded here: Full-size scan of paper slide-rule Full-size scan of diagrams As you can see, there are ten functions that trailblaze the slide rule, and each can be used in conjuction with everyday life; whether you are a air pilot or land junkie. Let's go step by step on their functions: 1: Multiplication To multiply with the Navitimer, use the unit alphabetize (number "10" in red on the inner scale).Unchanginglyset the multiplier (the number by which flipside is multiplied) opposite the unit alphabetize on th einner scale and read the wordplay on the outer scale opposite the multiplicand number (number to be multiplied by another) seeming on the inner scale. Example: To multiply 7 x 12, set 12 (the multiplier) on outer scale opposite unit alphabetize ("10") on the inner scale. Opposite 7 (the multiplicand) on the inner scale, read the wordplay 84 on the mobile dial. 2: Division To divide with the Navitimer, moreover use the unit alphabetize (red "10). Place the dividend (the quantity to be divided by flipside number) on the outer scale opposite the divisor (quantity by which flipside is divided) on the inner scale. Opposite the unit alphabetize (numeral "10" on inner scale), read wordplay on outer scale. Example: Divide 120 by 4. Place 120 on outer scale opposite 4 on the inner scale. Read answer, 30, on outer scale opposite unit alphabetize (numeral "10" on inner scale). 3:GingerlyGround Speed The mobile outer and stock-still inner scales are used for determination of ground speed problems. Two of the pursuit quantities are misogynist for its solution: time, distance, ground speed. Example: Known:Loftinessand Time: Required: Ground Speed. A pilot finds by the use of checkpoint that he has traveled 104 miles in 35 minutes. What is the ground speed? Solution: Move the mobile scale until 104 on the mobile scale is set opposite 35 on the stock-still scale. Opposite the hour alphabetize (the thunderstroke marked "MPH" directly over the hour 12) read 178 miles per hour on the mobile scale. 4:GingerlyGround Speed (Function 2) Example: Known:Loftinessand Speed. Required: Time. A pilot wants to know how long it will take to go 486 miles at a ground speed on 156 miles per hour. Solution: On the mobile scale set 156 opposite the hour alphabetize on the stock-still scale. On the inner scale opposite 486 on the mobile scale read 187 minutes (or 3 hours and 7 minutes). 5:GingerlyMiles per Minute This may be read without the speed in miles per hour has been obtained. The speed given in miles per hour on the mobile scale when set opposite the hour alphabetize on the stock-still scale can be readily converted into miles per minute by reading the number on the mobile scale seeming opposite the icon "10" on the stock-still scale. The icon "10" is often referred to as the "unit index". Example: In the previous example, the ground speed was 156 miles per hour. With the 156 on the mobile scale set opposite the hour index, what is the speed in miles per minute? Solution: With 156 miles on the mobile scale set opposite the hour alphabetize read the speed in miles per minute, or the icon on the mobile scale which appears whilom the icon "10" on the stock-still scale, which is 2.6 miles per minute. There are times when a pilot may want to know the time required to travel a short distance, such as the loftiness from the cone of silence to the whet of an airport, or between the inner marker and range station. Since the loftiness is short, the time required may be less than a minute, in which specimen the time has increasingly siginificance when expressed in seconds. In such cases the "second" alphabetize is used. This is the icon "36" on the inner scale (there are 3600 seconds in an hour). 6:GingerlyGasoline Consumption Two of the pursuit quantities are misogynist for gasoline consumption problems: Total gallons used, time, rate of consumption. Example: Known: Time and rate of consumption. Required: Total gallons used. A pilot wishes to know how many gallons are necessary to fly 3.5 hours at an stereotype rate of consumption of 11.5 gallons per hour. Soultion: Opposite the "hour index", set 11.5 on the mobile scale. Then, opposite 210 minutes on inner scale on the mobile scale read 41 gallons. 7:Gingerlythe rate of climb or descent Two of the pursuit quantities are misogynist for solution: total upland of descent, time and rate of descent (or climb). Example: Known: Rate of takeoff and total elevation in ascent. Required: Time. A pilot climbs to 7400 feet whilom his starting point at the stereotype rate of 500 feet per minute. How long will this require? Solution: Set 500 on the mobile scale opposite the "unit index" ("10" on the stock-still scale). Opposite 7400 on the mobile scale, read answer, 14.8 minutes on the stock-still scale. 8:Gingerlythe loftiness of climb or descent Two of the pursuit quantities are available: Distance, time, speed. The methos used in examples 4 and 5 should be used. Example: The pilot in the previous example wishes to know how fat he will have traveled when his climb is finished. His stereotype true air speed is 120 miles per hour and he is aided by a tail wind of 20 miles per hour. Solution: Set 140 miles per hour (120+20) on the mobile scale opposite "hour index" on stock-still scale. Opposite 14.8 minutes (computed from example 7) on stock-still scale read 34.5 miles on mobile scale. 9: Nautical and statute mile conversion On the stock-still scale both nautical (Naut.) and statute (Stat.) miles are shown; moreover shown are Kilometers (KM) (red mark just to the right of the MPH). The conversion from statute to nautical or nautical to statute miles is read directly on the mobile scale. Example: Known: 60 statute miles. Required: Nautical miles. Solution: Set 60 on mobile scale opposite "Stat." on stock-still scale. Opposite "Naut." on stock-still scale, read 52 nautical miles on mobile scale. 10: Nautical and statute mile conversion (Function 2) Example: Known: 60 Stature miles. Required: Kilometers. Solution: Set 60 on mobile scale opposite "Stat.". Opposite the "KM" mark (the red mark, just to the right of "MPH" on the stock-still scale), read 96.5 kilometers on the mobile scale. And you may have once thought the Slide Rule was just placed purely for cosmetic purposes. Look at the utility that it will provide you in the future! Now that you've been armed with this information, go out there and do some old-fashioned hand calculating!

Member 32 3,451 posts Gender:Male Location:Toronto, Canada Report post Posted March 26, 2008 My old school Navi is accurate, but the current version is off. Even with well-judged markings it is difficult to get an well-judged reading though. The markings are so small that it is nonflexible to determine if the result of an equation is 72 or 73 for instance. But overall it can be a handy tool when in a pinch, and a fun toy to impress your friends with! Share this post Link to post Share on other sites scoobs1971    7 scoobs1971    7 Almost there...
