3. Measure and record the monitor width DDM (DS), the monitor course DDM (CL), and the
modulation equality (carrier feedline DDM) on Navia Aviation Form “Localizer Monitor Ref-
erence Data”.
4. Check the quality of the identification and voice for clarity and correct information. If
acceptable, record a check mark under the appropriate column. This check may be omit-
ted when completing the line entry from the RMM.
5. At two-frequency localizers, complete the steps above for the clearance transmitter.
6. To obtain a computer generated data report of normal readings, log onto the facility to be
recorded, check that the transmitter to be recorded is “On Antenna”. The report may be
printed by interacting the “Print report” window in the File menu. Include the Front Panel in
order to inform which transmitter was “on antenna” during measurements.
7. At all dual equipment facilities complete a normal line entry for each set of equipment.
5-11 LOCAL AND REMOTE MONITOR SHUTDOWN OPERATION.
a. Object.
This procedure provides a method to determine that a shutdown is properly sensed at the
local and/or remote control points.
b. Discussion.
Certain alarms in the ILS equipment shall result in an equipment transfer and/or shutdown.
Also, if remotely monitored, an indication that the facility is shut down shall be received at the
remote monitor location. This check confirms that the shutdown occurs and that the remote
control point is properly notified. This check can also be initiated and monitored from a
remote maintenance monitor (RMM) location.
c. Conditions.
The facility is operating normally. Advance coordination of this maintenance activity with air
traffic control personnel is required.
d. Detailed Procedure.
1. Simulate a continuous alarm, or from the RMM perform a station integrity check.
2. Allow a shutdown to occur.
3. Determine that the proper remote and local alarm indications occurred.
4. If remote restore capability is installed, restore the facility from the remote control point or
allow the auto-restart circuit to restore the facility.
5. Make an entry in the facility log that this check was completed.
5-12 NORMAL GROUND CHECK.
a. Object.
This procedure provides a method to determine that the localizer course alignment, width, and
clearance are within tolerance.
b. Discussion.
Navigational information provided by the localizer is a complex function of the localizer sys-
tem. It is affected by the airport geometry, antenna system phase and current distribution, and
