AIRWAYS COMMUNICATION SERVICE 807 



entirely distinct from the government's program of Aids to Air 

 Navigation. That service contemplates one-way radio telephony and 

 direction finding on long waves. The government service is to be 

 available to all flyers who equip themselves to receive it. The two- 

 way system is for private communication and despatching service of 

 air transport companies which wish to control their planes in flight, 

 and to remain in constant communication with their pilots and 

 passengers. 



Also, although not yet required, it can safely be predicted that at 

 busy airports there will soon arise a need for radio means to control 

 precedence in the take-off and landing of airplanes. This virtually 

 amounts to traffic control and can be accomplished by low-power 

 two-way radio telephone. Planes wishing to land may announce 

 themselves and remain aloft until directed by the airport manager in 

 the control tower to land at a designated part of the field. 



In all these present and future problems, it is the policy of the 

 American Telephone and Telegraph Company and the Bell System 

 to assist by developing ways and means for making available to 

 commercial aviation the best possible communication service.
