INTERNATIONAL Airworthiness Standards

WRITTEN immediately following the author's return from the International Civil Aviation Conference held in Chicago in November, 1944, this paper outlines the history and present status of civil airworthiness standards, particular emphasis being placed upon the pros and cons of international uniformity.

Existing American Civil Air Regulations, Mr. Warner points out, may undergo extreme changes, should the draft drawn up at the conference be adopted, which considered possible bases of worldwide agreement. Some of the divergences are:

1. 1.
   The requirement that operating manuals be provided for all types of aircraft, not merely for transport types.
2. 2.
   The proposal to double the present requirement for minimum rate of climb for transport types with one engine stopped, raising it from about 100 to 200 fpm.
3. 3.
   Introduction of more flying-quality specifications than have heretofore appeared in general regulations.

Favoring the adopting of international standardization himself, Mr. Warner suggests that it at least be given a fair and earnest trial.
