The Company was established as a Guild in 1929 in order to ensure that pilots and navigators of the (then) fledgling aviation industry were accepted and regarded as professionals. From the beginning, the Guild was modelled on the lines of the Livery Companies of the City of London, which were originally established to protect the interests and standards of those involved in their respective trades or professions.
