Under the International Collision Regulations, aircraft on the surface of the water are within the definition of " steam vessels." As such, they are required to carry lights, make sound signals and manoeuvre, both in respect of surface vessels and of each other, in a manner that is not, in some instances, possible for them, due to the physical limitations of aircraft. At the same time, they can and should take upon themselves some definite measure of responsibility for the avoidance of collisions between surface vessels and aircraft on the surface of the water, and it is necessary that their rights and duties, when on the surface of the water, should be defined.

In order that an international agreement may be reached covering those provisions of the International Collision Regulations which apply to surface vessels and to aircraft on the surface of the high seas and on the waters connected therewith, navigable by sea-going vessels, the Conference recommends, in the interests of safety of life at sea, that this question should be studied by the competent authorities in the countries concerned, so that there may be an exchange of views, and an endeavour made to arrive at an international agreement. The Conference requests the Government of the United Kingdom of Great Britain and Northern Ireland to take the necessary action in the matter.
