2. A dvm.
3. BIRD wattemeter.
NOTE:
Chapter 1, Paragraph 1-2b, Test Equipment, discusses external test equipment and BITE,
and their proper use in the NAS. Particular attention must be paid to the proper use and main-
tenance of test equipment to ensure accurate evaluations of equipment operation. For
instance, when using a BIRD wattmeter for power measurements, the same set of rf bodies,
wattmeter, and elements must be utilized due to the variability of the wattmeter components.
For BITE, proper calibration and verification of measurements are required.
d. Conditions.
The facility is operating normally. For facilities that are equipped with standby equipment,
switch standby equipment on-line to take readings.
e. Detailed Procedure.
At the local site or RMM location, perform the following steps.
(1) Measure and record the normal course SBO dc voltage on Navia Aviation Form “All Glide
Slopes Normal Radiatied Parameters”.
(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 “All Glide Slopes Normal
Radiatied Parameters”.
(4) 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 active to the antennas during measurements.
(5) At all dual equipment facilities complete a normal line entry for each set of equipment.
5-41 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.
