In the design and application of electrical control equipment the problem of obtaining complete field data and requirements is always present in some degree. The problem is acute in branches of the electrical industry supplying aircraft control. Three factors contribute to the difficulty: 1. The tremendous engineering effort centered in the aircraft industry causes rapid technical changes that soon make accumulated data obsolete. 2. Technical data on utilization devices are not always available to either the aircraft or electrical manufacturer. The mushroom growth and technical advance of the aircraft industry have, in some cases, outdistanced laboratory equipment and personnel capacity so the data an electrical-control manufacturer would like to have are simply not available. 3. The secrecy surrounding many aircraft developments blocks the passing of information from the aircraft manufacturer to the electircal manufacturer.
