• Click the contact signal in the ESM Display to determine contact bearing and to view the source
of the signal (e.g. Kirov, Helix, etc.). You can also click and drag the triangle cursor around the
bearing indicator to center it on a contact.
■ The bearing of the contact appears in the Bearing field.
■ The class name of the contact appears in the Source field. It may take one or more sweeps of
the display before the class is identified.
3. Estimate the proximity of the contact. Take note of the intensity of the contact on the ESM
Display and the number of ESM Indicator lights that are lit.A strong signal can indicate that the
contact is relatively close.
4. Send the bearing data to the TMA station.
• When the cursor is centered on a signal, click MARK .This assigns an alphanumeric contact ID to
the contact and sends it to TMA and the Nav map. ESM contacts have E designations (E01, E02,
etc.)
