• Step 3—on the inner scale, place 20, which represents 2,006 opposite 26.5 on the outer scale (26.5 represents 26,500). 

• Step 4—opposite the index, 10, on the inner scale read 13.2 on the outer scale. Determine the value of 13.2 by estimating: 20,000 ÷ 2000 = 10, so 26,500 ÷ 2,006 = 13.2. 

The arm (–78) is negative, so the CG is also negative. 

The CG is –13.2 inches or 13.2 inches ahead of the datum. 

## Dedicated Electronic Flight Computer 

Dedicated electronic flight computers, like the one in Figure 10-5,  are programmed to solve many flight problems such as wind correction, heading and ground speed, endurance, and true airspeed (TAS), as well as weight and balance problems.

The problem just solved with an electronic calculator and an E6-B can also be solved with a dedicated flight computer using the information shown in Figure 10-2 . Each fligh computer handles the problems in a slightly different way, but all are programmed with prompts that solicit the required data to be inputted so there is no need to memorize any formulas. Weight and arms are inputted as called for, and a running total of the weight, moment, and CG are displayed.
