Airfield Safeguarding

Airfield Safeguarding & Development

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, bringing

safeguarding maps into the twenty-first century.

Using the airfield data, ASD completes an analysis to CAP 168 and provides all the plotting

data, an overlay graphic, and various other files. The graphic uses either a contour or

squared colour-coding system 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. This can then be

presented to the LPA, together with instructions for its use. A file is also provided 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.

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.
