History of Gander Aeradio
In 1935 officials of the British
Air Ministry visited Newfoundland and selected Botwood as a flying boat
base and the site of Gander as a suitable land plane base. Land planes
at that time already started to replace the flying boats as a result of
advances in the air industry developments which made land based planes
more feasible for long distance travel. With this shift of attention in
aviation and with the completion of the new airport, radio operations
moved from Botwood to Gander on November 30, 1938.
The need for a radio link to
aircraft arose so ground personnel could communicate with aircraft the
course of their journey across the North Atlantic. At that time
wireless operators handled all takeoff and landing instructions and Air
Traffic Control was not a separate entity in communications or control
as we know it today. In addition, a distress and safety watch was
maintained and regular progress reports were solicited from aircraft at
predetermined points of longitude and latitude. Although today control
does not rest with Aeradio, it is still the responsibility of the Flight
Service Specialist to maintain this communications link which is so
vital. During these early years in Radio and Aviation, propagation also
posed its share of problems in maintaining this link. Selection of
appropriate frequencies had to be made so that communications would not
be lost as aircraft disappeared over the horizon.
All air/ground communications to
and from aircraft at that time were transmitted by radio operators using
International Morse Code, as radio telephony was not introduced until
1948.
Up until 1941 the British Air
Ministry had been in charge of radian operations at Gander with the
exception of a few months when Canadian Pacific took over.
With the outbreak of World War
II the Atlantic Ferry Organization (ATFERO) assumed control of Aeradio
due to increased demand for efficient communications. Gander’s
strategic location made it an important stepping stone to Europe for
aircraft that were being ferried to the war zone from the United States,
with Aeradio responsible for North Atlantic communications west of 30
degree Longitude. It was around this time that Aeradio became known as
the “Signals Centre” or “Signals” for short.
As the war continued, the Royal
Air Force Ferry Command, which later changed its name to the RAF
Transport Command, assumed control of the operation. Under the
jurisdiction of these two military organizations radio operators were
dressed in uniform, even though they remained civilians. As reiterated
by some of the veterans of Aeradio, not all the work done at Signals was
aircraft related. After the German Pocket Battleship “Bismarck” sank
the HMS Hood off the coast of Norway, she made course back to Germany,
requesting assistance from the German Admiralty along the way.
”Signals” intercepted these messages, plotting her course and sent
bearings off to White Hall in London as they were received. From this,
the British Navy was able to track the Bismarck and finish what the Hood
and other ships were not able to do alone.
News was not so well received
when the Caribou was sunk in the Gulf of St. Lawrence, October 14,
1942. “Signals” had been picking up messages from five U-Boats in the
area before the disaster.
After the war, the Civil
Aviation Division of the Newfoundland Government assumed control of
radio operations until it was passed to the Canadian Air Transportation
Administration. This department, which holds control to the present
day, assumed responsibility for all communications relevant to the
operation of transatlantic crossing and controls whilst en route.
With the introduction of radio
telephone in 1948 and with the increase in the AOR (area of
responsibility) for Gander in 1950 when oceanic control moved from
Moncton to Gander, Aeradio entered a new era in Canada Aviation
history. Operations continued to improve as an expanded number of
frequencies were introduced when the present building was built and
commissioned in 1957.
The 1960s saw further
improvements and developments in technology of electronic equipment such
as, transmitters, receivers, teletypewriters and landline connections
but apparently technology could not keep abreast of increased demands by
multi-international air carriers requesting the services of Gander
Aeradio during their regular flights across the North Atlantic. This
led to the last major developments of the 1970s when the reporting
system became fully computerized, thereby, increasing the speed which
in-flight communications could be processed. The change from AM
(amplitude modulation) to SSB (single sideband) transmission also took
place during this period.
This year, 1986, will mark a new
milestone when Gander International Flight Service completes its planned
move and enters the latest state-of-the-art technology of the eighties.
Today, Gander International
Flight Service Station is the largest aeradio station operated by the
Ministry of Transport in Canada, both in terms of volume of messages and
the number of staff. Fifty-four specialists operate on a continuous 24
hour rotating shift under a mandate from ICAO (International Civil
Aviation Organization) to provide for the safe and expedient movement of
aircraft with the 1,152,000 square miles of Gander’s oceanic area. In
maintaining a liaison between aircraft and ATC, last year Gander IFSS
provided communications to approximately 115,000 aircraft, resulting in
about a half million contacts. These contacts included everything from
enroute safety messages, company reclearance messages, significant
enroute weather information and dangers to navigation, not to mention
distress communications and communications of an urgent nature. In
addition to the nine air/ground circuits, the station also operates a
weather broadcast position, known as Volmet, sending out two ten minute
weather broadcasts every hour.
