Breitling ring flight slide one of the uses: multiplication of two numbers. To calculate 12x7, rotate the outer scale 12 to the position corresponding to the inner scale ▲ 10. At this time, the outer scale corresponding to the inner scale 7 is 84, which is the result of 12x7. Breitling ring flight slide the use of two: the difference between the two numbers. To calculate 120 ÷ 4, simply rotate the outer scale 12 (= 120) to the inner scale 40 (= 4). At this time, the outer scale of the inner scale 10 10 corresponds to 30, which is 120 ÷ 4 results. Breitling ring flight slide the use of three: distance conversion unit. To convert 1,800 miles to kilometers or nautical miles, simply rotate the outer ring scale 18 (ie, 1800) to the red inner milestone (▲ STAT) where the inner ring kilometers (▲ KM) corresponds to the outer ring The value of 29 means 2,900 km converted. The outer ring value corresponding to the ▲ NAUT of the inner ring is 15.6 nautical miles for the conversion. Breitling ring flight slide usage Secret 4: a simple exchange rate conversion. Suppose the pound against the euro exchange rate of 1 pound = 1.1 euros, simply rotate the outer ring scale 11 to the inner scale ▲ 10, a series of conversion data can be easily read, the inner scale represents the pound value, the outer scale represents Corresponding to the euro value. That is: 40 pounds = 44 euros, 80 euros = 72.7 pounds. Breitling ring flight slide five: flight landing time calculation. For example, how long does it take for pilots to land at 3300 meters at 1 meter per second, or 60 meters per minute? Just rotate the outer ring value 33 (= 3300) to the inner ring value 60, and the outer ring value 55 corresponding to the inner ring scale ▲ 10 is the requested time, which is 55 minutes. Breitling ring flight slide usage six: access to the landing schedule. For example, a pilot who descended at a speed of 60 meters per minute and mapped this landing rate at a rate of 10 ° to the inner circle at a scale of 10 would give a schedule of descending any height: a 33-minute drop in 55 minutes and a decrease in 1,800 meters 30 minutes, down 900 meters need 15 minutes, at a glance.
