Note: 1) The frequency in this label is the frequency to which the NAV radio is tuned plus 100
MHz.
2) The DME does the translation to the required DME frequency.
3) The SDI bits of the NAV radio are used to determine the DME number as shown in
Table 22 .
4) The SDI bits for Label 035 should always be set to “All Call”, if a scanning DME is used.
5) The Sign Status Matrix is always set to Verified.
5) Table 21 defines the bit definitions for the navigational source, which will be set to ILS or
VOR mode as determined by the NAV frequency received.
