Question: Are the color, line weights and line types referenced in AC 150/5300-18b mandatory?
Answer: No. The CADD symbology standards in AC 150/5300-18B are for reference only. They do not impact data loaded to Airports GIS. So color, line weight and line types can vary. Use the guidelines in AC 150/5300-18b if you like.Return to the Airports GIS Table of Contents:
