beacon also facilitates identification of the plane to be controlled at the
time of initial pickup.
The operational use made of the SCR-584 as modified for aircraft
control was basically any that required precise navigation under restricted
visibility. Large aircraft could carry radio and radar navigational aids
which often made it possible for them to carry out such missions without
assistance, but the fighters and fighter-bombers of the TAC’S had neilhcr

space nor operators for such equipment. Their navigational aids had
to be external to the aircraft.
A total complement of 8 officers and 38 enlisted men was required to
operate a single control SCR-584, the majority of these men belonging to
the organization involved in making use of the radar data.
7.8. Teleran.—The examples of operational radar systems will be
closed with a brief account of a system still in the developmental stage.
It is called “Teleran” (for Television Radar Air Navigation) and
involves the coordinated use of air and ground equipment.
The basic idea of Teleran is that high-performance ground radar, if
supplemented by simple and reliable height-finding means and by
