The receiver detects the three (3) marker tones, outer,
middle and inner, and illuminates the appropriate marker
beacon indicators. The marker indicators are located to
the left of the Altimeter on the PFD (Figure 6.2.3). The
outer marker frequency is 400 Hz with a blue indicator,
the middle marker frequency is 1300Hz with an amber
indicator and the inner marker frequency is 3000 Hz with
a white indicator. Refer to Table 6.2.1 for a summary of
the marker beacon signal characteristics.
