SAFEGUARDING SERVICES FOR THE SMALLER AIRFIELD

All licensed airfields have to safeguard themselves, however small. If yours is an unlicensed airfield, HM Government advises that it should also be safeguarded, and in CAP 738 the CAA recommends that it is safeguarded to the same parameters as those that are licensed. Whether licensed or unlicensed, a fully prepared and printed safeguarding map could well be unecessary and beyond your means.

Given the necessary airfield data, ASD can carry out the analysis (to CAP 168) and then provide all the plotting data necessary with an overlay graphic that can be printed out to scale. The graphic uses the square colour-coding system that the CAA recommends in CAP 738, and, 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.

In addition to the squared safeguarding chart, ASD now produces a choice of contoured safeguarding charts. One uses the height bands recommended by the CAA (to the left), the other shows colour-coded contours at 5mAGL intervals. In these cases, manual plotting is not really viable, so printing a map overlay or displaying in Google Earth^© are the practical options. This will result in fewer applications for checking.
