User manual ASA AIR CLASSICS E6-B

[. . . ] E6-B Flight Computer Instructions This instruction booklet can be used with the three different E6-B models available from ASA. If you have a different model than the one depicted, some parts of your computer may appear slightly different from the computers pictured in this booklet. However, the calculations are accomplished with the same method and produce the same answers. © 1992 ­ 2000 ASA Aviation Supplies & Academics, Inc.

[. . . ] GAL are provided on both middle and outer scales to help you convert between these quantities. gallons will always be larger. Figure 10 You have purchased fuel in Canada and the delivery slip says 32 Imperial gallons. gallons on the outer scale. Quantity/Weight Conversions Aviation gasoline weighs 6 pounds per U. S. For weight and balance calculations, aviation gasoline weight-per-gallon can be determined by lining the U. S. GAL arrow on the middle scale with the FUEL LBS arrow on the outer scale. Fuel gallons are read on the middle scale and fuel weight on the outer scale. Read 192 pounds on the outer scale opposite of 32 gallons on the middle scale. See Figure 11. Figure 11 Similarly, oil weight may be determined by lining the U. S. GAL arrow on the middle scale with the OIL LBS arrow on the outer scale. Oil gallons are read on the middle scale and oil weight is read on the outer scale. To find the weight of 2 gallons (8 quarts) of oil: 16 Figure 12 1. Read 15 pounds on the outer scale opposite of 2 gallons on the middle scale. Imperial gallon weight of fuel and oil may also be determined in the same manner by lining up the IMP. GAL arrow on the middle scale with the FUEL LBS or OIL LBS arrow on the outer scale. gallons, pounds to kilograms, or feet to meters by aligning the appropriate arrows on the middle and outer scales. Any value in pounds on the outer scale will be opposite of its converted value in kilograms on the middle scale: 2, 000 lbs is 901 kg, and 160 kg is 351 lbs. Line up the true or outside air temperature (do not use Indicated Air Temperature) opposite this Mach No. Mach Number on the inner scale reads opposite True Airspeed (in nautical miles per hour) on the outer scale. In Figure 14, at an outside air temperature of +15°C and Mach 1 (10 on the inner scale), read 661 knots on the outer scale. Figure 14 20 True Altitude When the air is colder than standard your altimeter can mislead you into thinking you are higher than you actually are. Determine pressure altitude by setting 29. 92 momentarily on the altimeter. Set pressure altitude next to outside air temperature in the altitude correction window. Subtract station altitude from indicated/calibrated altitude to determine calibrated altitude AGL. [. . . ] The wind correction angle is measured right or left of the center line. Be sure to count the degrees accurately -- the value of each line changes at the 100, 150, or 250 knot arc, depending on the E6-B model you are using (see Note below Figure 21). Example: You have laid out a course on a sectional chart and measured it to be 090° true using your plotter. The winds aloft forecast calls for the wind at your chosen altitude to be 230° at 18 knots, and the performance data for the airplane says that you can expect a true airspeed of 125 knots at that altitude. 1. Using any convenient starting point, measure 18 units up from the grommet toward the TRUE INDEX and make a dot at 18 units (see Figure 22). [. . . ]
