File Name/Version wsc07d

Names:: TP Names are alphabetical with WSC (the home base)listed first with a preceding numeral one
Elevations:
Many Elevations are rounded.
Classification of each TP is contained in the name:
Last 3 characters of each TP will be one of these three: -R = Runway on sectional, -E = Emergency Landing area, -U = Unlandable area
Qualification:
After the letter is a qualification number: 1, 2, or 3 is good, 7, 8, or 9 is bad.
Comments at end of line may include:
Runway size:
           Length in hundreds with H for Hard or S for Soft surface e.g. "20H" means 2000 ft hard surface
          Width in feet follows followed by a "W" e.g. "25Hx90W" 2500 long x 90 ft wide
          Width sometimes is the paved area othertimes estimates width containing 2 ft obstructions
          Type of runway surface H=Hard (concrete/ asphalt/paved) S=Soft (gravel sod or dirt)
Runway direction e.g. 14/32, N/S, 16/34
Radio frequency e.g. 22.9=122.9 or 22.7=122.7 UNICOM, ATIS, AWOS, ASOS, Aviation Weather e.g. AW24.5=124.5, Control Tower Freq e.g. CT18.7=118.7
Landing Sites
Choice of landing sites is a pilot's personal responsibility.
A Landing Attribute "L" has been amended to a few of the control points that MAY have been landable in the past, but they may not be landable any longer. The only "A" attributes is at WSC.
Pilots must decide for themselves which control points may be landable for them, and then add or delete attributes as appropriate.
