In every country where agricultural aviation is done as a private enterprise, some system of rules and regulations is sure to exist and the International Agricultural Aviation Centre has collected data on this subject.

To imagine, however, that a system of regulations, ideally suited to all cases, could be drawn up on a basis of these national rules is an illusion. Every country—and this holds true for many spheres—is blessed or cursed with the laws it deserves. For all these systems of laws and regulations are determined partly by internal and partly by external factors. Let us compare two countries. One is densely populated with intensive agriculture, the other sparsely populated with extensive agriculture. It is obvious that the first country will have a more comprehensive system of regulations in regard to agricultural aviation than the second country. The denser population necessitates a higher grade of protection against the dangers from both the aircraft themselves and the drift of toxic chemicals. Quality agriculture demands quality work from the aerial applicator.
