Ai Mark VIII

Synopsis

In December 1942 the first RAF squadron was equipped with AI Mark VIII, the main production version of the first centimetric Aircraft Interception radar system. This film explains in detail how AI Mark VIII works: the function of the spiral scanner and how its movements relate to images on the PPI (plan position indicator); aircraft interception; IFF (identification friend or foe); indication; homing beacon and beam approach.
