THE airways division operates in
conjunction with the weather bureau
in disseminating weather information
along the airways and maintains
series of radio stations for the eX-
change of weather information and
the dispatch of airplanes. This system
of communication is supplemented by
telephone and teetype for point-to-
point communication. Three radio
broadcast stations are now operating
at Hadley field. BeiIefonte and Cleve-
land, and broadcast weather informa
fioa and landing conditions at the air
ports and principal intermediate fields
along the route throughout the day
and night.
THE telephone transmitters are
2,000watt capacity, broadcastlng the
voice in the band between SO and
$50 kiloeyeles with q reliable range
of Us miles.
Pilot Can Alter Course.
Before taking off, the pilot may
obtain complete weather data cover

departure, will receive hourly reports
