Which data point corresponds to Echo?

Which data point corresponds to Echo?

• A. Intersection of 90 & 89
• B. I-10 & 89
• C. 89 & 87 & power lines
• D. Intersection of power lines and Blackwater river

Answer: (B)

Echo is the data point located at the crossing of Interstate 10 and Highway 89. On your navigation chart, each named data point (Alpha, Echo, etc.) corresponds to a specific fix defined by the intersection of two features. Here, the chart designates Echo exactly at where I-10 intersects 89. The other described intersections or features (such as 90 with 89, 89 with 87 plus power lines, or power lines with the Blackwater river) are different fixes, not Echo. So the data point Echo is that crossing of I-10 and 89.
