  • On initial contact say the complete callsign - always use full callsigns when establishing communications
  • After good communication has been established the abbreviated callsign may be used when initiated by ATC

  • Always pronounce each digit separately
  • Use the company radio callsign if possible (as shown on the flight strip in IvAc)
  • If company radio callsign is unknown, spell the callsign using the NATO Alphabet

  • Start with a call and a reply to establish contact, except when it is certain that the call will be received. After contact has been established, further identification or call until termination of the contact.
