NOTE
At Todendorf, the visual threat type may not coincide with the EW types on page 025 and the
AN/APR-39 indicator; that is, the visual object may not look like the EW threat specified for
that location.
8-96. The EW threats are activated in either a manual or automatic mode of operation. In both modes, the flight station
must be integrated with the visual system. In the manual mode, the instructor edits the ACTIVE column (column 2) of
the threat array page for the particular threat to be activated. Applicable activity levels are shown at the bottom of the
threat array page. For the automatic mode of operation, the instructor should set line 11, column 2 to a 1. As soon as a
line-of-sight (LOS) between the aircraft and threat has been established, the visual signal of the threat appears on the
APR-39 indicator, and an audio tone can be heard over the pilot and copilot headsets. In the automatic mode, the threat
automatically advances to the next most lethal mode as long as the LOS has not been broken. In the manual mode,
threat modes are not upgraded.
