Refer to the current Denver sectional excerpt. Chaparral, a private airstrip, is charted with the data block "5930 - 40." What is the length of its longest runway?
Why: This chart's "Additional Airport Information" legend defines the data block format: the number after the dash is "Length of longest runway in hundreds of feet; usable length may be less." For Chaparral, "5930 - 40" is a field elevation of 5,930 feet and a longest-runway length of 4,000 feet (40 hundreds).
Misreads "40" as a raw figure in feet rather than hundreds of feet — the chart's own legend states runway length is given in hundreds of feet.
5,930 is the field elevation (the number before the dash), not the runway length, which follows the dash.
