Helping Airfields Develop Safely
 If you run a small airfield, HM Government advises that unlicensed airfields should also be safeguarded,  and in CAP 738 the CAA recommends that they are safeguarded to the same parameters (CAP 168) as  those that are licensed. Whether licensed or unlicensed, a fully prepared and printed safeguarding map  could well be unecessary and beyond your means. So ASD has devised a cost-effective package, provided  electronically, bringing safeguarding maps into this century.  Using the airfield data, ASD completes an analysis, usually to CAP 168, and provides all the plotting data,  an overlay graphic, and various other files. These include one for uploading into Google Earth® (GE),  placing the overlay over the ground image of the airfield, at the correct scale. This is the easiest way to use a SG chart,  enabling the user to zoom in upon the area in question. The graphic uses a contour colour-coding system using height  bands suggested by the CAA in CAP 738. With the comprehensive instructions provided, it can be used to produce a  safeguarding chart overlaid on an OS map. A package can then be presented to the LPA, together with instructions for its  use.  As an optional extra, ASD can provide a GE 5mAGL contour overlay, enabling airfield operators to  easily assess the maximum permissible structure height (AGL) at any position. This is a much  cheaper, quicker, and easier method than expensive software solutions.   An additional source of advice for the smaller airfield can be found in the form of factsheets at the  GAAC website, for which ASD is honorary safeguarding advisor.
