2.4 Scheduling

Parent topic: 2 – Promulgation of Maritime Safety Information

2.4.1 Automated methods (NAVTEX /SafetyNET)

  2.4.1.1 Navigational warnings shall be broadcast as soon as possible or as dictated by the nature and timing of the event. Normally, the initial broadcast should be made as follows:

  • .1 for NAVTEX, at the next scheduled broadcast, unless circumstances indicate the use of procedures for VITAL or IMPORTANT warnings; and

  • .2 for SafetyNET, within 30 minutes of receipt of original information, or at the next scheduled broadcast.

  2.4.1.2 Navigational warnings shall be repeated in scheduled broadcasts in accordance with the guidelines promulgated in the NAVTEX Manual and International SafetyNET Manual as appropriate.

  2.4.1.3 At least two scheduled daily broadcast times are necessary to provide adequate promulgation of NAVAREA warnings. When NAVAREAs extend across more than six time zones, more than two broadcasts should be considered to ensure that warnings can be received. When using SafetyNET in lieu of NAVTEX for coastal warnings, Administrations may need to consider an increase in the number of scheduled daily broadcasts compared with the requirement for NAVAREA warnings.

2.4.2 Schedule changes

  2.4.2.1 Broadcast times for NAVTEX are defined by the B1 character of the station, allocated by the coordinating Panel on NAVTEX Services of the Sub-Committee on Radiocommunications and Search and Rescue.

  2.4.2.2 Times of scheduled broadcasts under the International SafetyNET service are coordinated through the International SafetyNET coordinating Panel.
