Sec. 1271.22. Moving aircraft to be under control and in contact with tower

All aircraft which are being taxied, towed or otherwise moved at the air terminal shall be under full control and shall move or be moved at a reasonable speed. Whenever any aircraft is being taxied, towed or otherwise moved on the public landing area, public ramp and apron area, public passenger ramp and apron area, or public cargo ramp and apron area, there shall be a person attending the controls of the aircraft who shall monitor by radio the transmitting frequency in use by the control tower or who, if necessary, will cause that frequency to be monitored by another person in the aircraft at the time. In the event of radio equipment failure, the control tower may use an aldis lamp for communication or the aircraft shall be escorted by a radio-equipped vehicle supplied by the airport operator.
