Influence of Electricity on Aircraft Instrumentation

Many factors have operated to set up conditions which have been very favorable to the electrification of aircraft instrumentation. Two tabulations are presented to indicate the extent to which electrical principles have been applied to common aircraft instruments. The effects of increased size in aircraft, larger power plants, longer flight time, association with other equipment, and other factors upon instruments are discussed. The advantages of electric instruments are presented, and some possible future developments are noted.
