CHART CHALLENGE
HOW LONG IS THE RUNWAY?
BY MACHTELD SMITH
It has everything to do with the chart scale and the available chart symbol
sizes. Runways up to 8,069 are enclosed in the familiar circular airport
symbol. For example, if a runway is between 7,970 and 8,069 feet in length,
charting specialists round it to 8,000 feet to equate a line of 0.192 inches
in length on the sectional chart scale and that fits the available symbol.
But, according to the FAA's Aeronautical Information Services, if a runway
is longer than 8,069 feet the representative line is too long to fit into the
largest circular airport symbol available. Therefore, charting specialists
place a line-work around the runway pattern forming a polygon (enclosed
shape) for anything over 8,069 feet in length. But beware; specialists also
place these polygons around the runway pattern of airports with multiple
runways that are less than 8,069 feet, in cases where the multiple runway
pattern does not fit into the largest, circular airport symbol. Now you know!
HERE'S A GREAT TRIVIA QUESTION FOR YOUR STUDENTS: DO THEY KNOW
WHY THERE ARE DIFFERENCES IN HOW HARD SURFACE RUNWAYS ARE
DEPICTED IN THE VARIOUS AIRPORT SYMBOLS ON SECTIONAL CHARTS?
They may know that the blue and magenta colors differentiate between
towered and non-towered airports, respectively. But why is there a
distinction between airports with hard-surface runways greater than 8,069
feet in length and those that are 1,500 to 8,069 feet in length? What is so
magic about those numbers?
