The cathode-ray tube will remain with us for many years but will eventually
be replaced by a matrix of electroluminescent elements.
Transistorized equipment is, of course, still marketed, but many of the
transistors, diodes and resistors now appear on integrated circuits. The
emergence of integrated circuits has revolutionized the design of air radio
systems. The use of IC techniques to produce microprocessors has opened up
a new world. Increased safety, increased payload, increased reliability and
improvement in performance allow flights to be made in conditions where
previously aircraft have to be grounded. Completely new systems do not appear
very frequently, although when they do, it is often because the improvement
in the state of the art made the impossible possible.
