The waypoint Igor refers to which intersection?

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

Answer: (B)

Waypoints like Igor are defined by the precise crossing of navigation signals, often two VOR radials, sometimes with a landmark to pin down the exact spot. Igor is located at the crossing of the 89-degree radial and the 87-degree radial, with a nearby power-line feature that helps confirm the position on the chart. That combination of two radials plus a landmark makes Igor a specific IFR fix, not simply a road intersection or a single radial intersecting a highway. The other options describe intersections that would not match how this fix is defined on the chart, so they aren’t the Igor waypoint.
