64. General.-a. It is the primary responsibility of the control tower
operator to observe traffic conditions around the immediate vicinity
of the airport and keep pilots advised of these conditions. However,
the presence of a control tower in no way relieves the pilot of an air-
plane of the responsibility of exercising every precaution within his
power to avoid hazardous situations. In some localities it is necessary
to clear local tactical or training flights by agencies other than control
towers.
b. Control towers within the United States will be designated by
the name of the field at which they are located, plus the word "tower."
(Control towers in oversea theaters of operations are not so designated.
Communication with them is established by the use of tactical call
signs.)
65. Take-off instructions.--a. Departing aircraft will contact the
control tower for take-off instructions prior to taxiing away from the
line or parking area and will not depart until advised to do so. Traffic
control tower operators at Army Air Forces stations will include the
following information in take-off instructions in the sequence given:
(1) Wind direction and velocity.
(2) Runway and field conditions.
(3) Special instructions concerning local conditions.
(4) Taxi clearance.
(5) Take-off clearance.
(6) Altitude of field and correct time-given only upon request of
pilot.
b. Example of take-off instructions:
Ship: "Scott tower__This is__(Call sign)__Over."
Tower: "(Call sign) _ This is_ Scott tower _Over."
Ship: "Taxi clearance_ _Over."
Tower: "Wind east twelve E one two. Field is soft, use east-west
runway. Heavy construction in progress southeast of field.
Taxi to west end of east-west runway. -_Over."
