Figure 1-14 Aerodrome 2

In Figure 1-14, the runway pattern is shown, but the length of the longest runway is not included.

Since the circle represents an 8000 foot diameter, we can infer the longest runway in this case is

at least 8000 feet since the pattern is wider than the circle. The actual location of the airport is at

the center of the circle.

An open circle depicts a major aerodrome on an ONC chart. The diameter of the circle

represents 6000 feet (1:500,000 scale). A runway pattern may or may not be shown. If no

pattern is included, the length of the longest runway in hundreds of feet may be included.

Figure 1-15 Aerodrome 3

elevation is 187 feet, (MSL). The actual location of the airport is at the center of the circle.
