South Africa has strategic requirements for tasks such as maritime patrol and border control. Research on UAVs should be done in order to design, certify and operate UAVs in civil airspace to satisfy these requirements. If principles such as ‘equivalence’, initially proposed by Eurocontrol are to be adopted in South Africa, it then follows that similar standards used by manned aircraft should be used by UAVs. Similarly, because the process of creating UAV regulations has not kept up with the pace of UAV development, and because dedicated UAV regulations do not yet exist in South Africa, UAVs must be tested and evaluated in order to prove compliance with comparable manned aircraft regulations in the foreseeable future until regulations are created or modified to accommodate UAVs. Given the airspace restrictions, and lack of applicable standards and regulations, proper flight testing of UAVs can become a very specialised task. Most test techniques applied to testing of manned aircraft are fortunately equally applicable to UAVs. This is a research-based paper that provides guidance to flight testers, UAV developers and research organisations wishing to execute tests in South Africa by suggesting a number of considerations for testing of UAVs.

In South Africa the modern outlook towards time may be said to have started in 1948. Both the two major observatories, The Royal Observatory in Cape Town and the Union Observatory (now known as the Republic Observatory) in Johannesburg had, of course, been involved in the astronomical determination of time almost from their inception, and the Johannesburg Observatory has been responsible for the official time of South Africa since 1908. However the pendulum clocks then in use could not be relied on to provide an accuracy better than about 1/10 second, which was of the same order as that of the astronomical observations. It is doubtful if much use was made of even this limited accuracy outside the two observatories, and although there may – occasionally have been a demand for more accurate time, it was certainly not voiced.

Abstract This article summarizes a series of trips sponsored by People to People, a professional exchange program. The trips described in this report were led by the first author of this article and include trips to South Africa, Russia, Vietnam and Cambodia, and Israel. Each of these trips included delegations of 25 to 50 speech-language pathologists and audiologists who participated in professional visits to learn of the health, education, and social conditions in each country. Additionally, opportunities to meet with communication disorders professionals, students, and persons with speech, language, or hearing disabilities were included. People to People, partnered with the American Speech-Language-Hearing Association (ASHA), provides a meaningful and interesting way to learn and travel with colleagues.
