[. . . ] 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. 7005 132nd Place SE Newcastle, WA 98059-3153 All rights reserved. [. . . ] Set the known value beneath the NAUT or STAT arrow as before, and read kilometers under the KM marking. For example, to convert 115 statute miles to kilometers: 1. See Figure 9. Figure 9 Try these sample problems: (Answers are on Page 37) 1. Gallons to Imperial Gallons Your Approved Flight Manual lists fuel capacity in U. S. gallons, but in many countries fuel is delivered in Imperial gallons. GAL are provided on both middle and outer scales to help you convert between these quantities. Your tanks are placarded to hold 64 U. S. How many Imperial gallons will they hold?GAL arrow on the middle scale opposite the IMP. Read 53. 2 Imperial gallons on the outer scale (see Figure 10). Because Imperial gallons are larger than U. S. gallons will always be larger. Figure 10 You have purchased fuel in Canada and the delivery slip says 32 Imperial gallons. Find 32 on the 15 middle scale and read 38. 5 U. S. 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.

If you have an autopilot and some free time, you can calculate the actual winds at your location and altitude. To solve an inflight wind problem you need your ground speed, true heading, true course, and true airspeed. Let's assume your true course is 180°, your true heading is 160°, your last ground speed 32 check came out to be 120 knots, and you calculate the true airspeed at your altitude to be 140 knots.
