2. Air carrier and other civil aircraft having FAA authorized call signs. State the call sign followed by the flight number in group form. NOTE- "Group form" is the pronunciation of a series of numbers as the whole number, or pairs of numbers they represent rather than pronouncing each separate digit. The use of group form may, however, be negated by four-digit identifiers or the placement of zeros in the identifier. EXAMPLE- "American Fifty-Two." "Delta One Hundred." "Eastern Metro One Ten." "General Motors Thirty Fifteen." "United One Zero One." "Delta Zero One Zero." "TWA Ten Zero Four." NOTE- Air carrier and other civil aircraft having FAA authorized call signs may be pronounced using single digits if necessary for clarity. ----- Original Message ----- From: "Michael A.
