Contributions

An authority on international air and space law, Cheng has been described as the "Father of International Air Law". During the height of the Cold War in the 1960s, Cheng investigated the United Nations General Assembly's resolutions 1721 A and 1962 regarding legal principles governing the outer space. He invented the theory of instant customary law, which states that opinio juris is the only necessary element for the creation of a new customary international law, which may be created "over night" as long as opinio juris about its existence is not rejected by member states of the international community. This theory has gained support over time.
According to the ISPL, Cheng's 1953 book, General Principles of Law as Applied by International Courts and Tribunals, is considered the most important treatment of the subject. He also published the books The Law of International Air Transport and Studies in International Space Law. The latter reprints his pioneering articles on international air and space law.
In 2017, Cheng donated his collection of more than 3,000 books and legal documents to Northwest University of Politics and Law in Xi'an, China, and NWUPL established the Bin Cheng Air and Space Law Library and the Cheng Tien-Hsi International Law Library in the memory of Cheng and his father.

Cheng was married to Katherine Fu Jinpei, the eldest daughter of Fu Bingchang, who served as ambassador of the Republic of China to the Soviet Union. The couple had a son and a daughter.
