Advances in airport lighting

Developments in airport lighting for combat purposes initiated a trend toward much higher candlepower for contact lights and much more expensive lighting equipment generally for commercial airports. The new tendency is a welcome departure from the all-too-common prewar practice of allotting only one per cent or less of the airport´s cost for lighted landing aids in spite of the failure of radio to provide adequate control in heavy air traffic. A combination of improved lighting with radio is offered as the only feasible method of affording the pilot the necessary margin of safety for landing or take-off.
