The following are some considerations that need attention when total counts are taken from an aerial platform. Type of aircraft There are several criteria which should be considered in the choice of aircraft. Some of these in order of importance are availability, visibility, safety, cost and speed (both slow flight and cruise characteristics). Unless equipped with a nose bubble or otherwise projecting turret, few low-wing aircraft provide acceptable forward and lateral visibility, although removal of baggage hatches or doors may help.

Unstructured populations If the species does not aggegate to pup, or if the number of aggregations is large, then some form of transect based survey will be required. If the entire area used by the species can be surveyed, the resulting counts will provide an estimate of the minimum size of the population which can then be corrected for the proportion of animals in the water at the time of the survey. However, this is rarely possible and it is usually necessary to survey some small fraction of the potential range of the species involved.
