1.2.1.3 Glidepath Description
To shape the glide path signal, ground plane reflection from an area in front of the antenna
array is necessary. The specific requirements to the area are given in the antenna handbook.
The glide path site may be located on either side of the runway, but the most reliable operation
will be obtained if the site is selected on terrain least obstructed by taxiways, aircraft holding
aprons, parking ramps, buildings, power lines etc. The site should offer the widest area of
smooth ground with possibilities of levelling without excessive physical or economical effort, if
indeed levelling is deemed necessary.
The glide path antenna system should be located at a distance of 75-200 m from the runway
center line. The distance from the runway threshold is a function of several factors upon which
establishment of the optimum operational conditions depend. These factors are:
GENERAL DESCRIPTION

1. The glide path angle.
2 Threshold crossing height requirements.
3. Obstruction clearance requirements
4 The slope of the terrain in front of the antenna system.
5. The extent of smooth terrain in the site area and beyond the threshold.
1.2.2
Product Type Numbers
The Normarc product numbering system is based on the following three levels:
• System
• Assembly
• Module
Systems have type numbers starting with NM, for example NM 7033. Systems consist of
assemblies, modules and parts.
Assemblies have type numbers consisting of three letters, a three- or four- digit number and a
letter, for example LPA 1230A. LPA is an abbreviation of Localizer Power amplifier Assembly,
1230 is a running number, and the last letter is the variant designator. Assemblies can consist
of assemblies, modules and parts.
Modules have type numbers consisting of two letters, a three- or four- digit number and a letter, for example FD 1235A. FD is an abbreviation of Feedback Detector, 1235 is a running
number, and the last letter is the variant designator. Modules consist of parts.

The ILS cabinets can be configured for Cat I, Cat II, or Cat III requirements with no basic
changes.
Eight models are available:
NM 7011
Single frequency LLZ
NM 7012
Single frequency LLZ with hot standby monitoring (Cat III)
NM 7013
Two frequency LLZ
NM 7014

Single frequency GP
NM 7032
Single frequency GP with hot standby monitoring (Cat III)
NM 7033
Two frequency GP
NM 7034

The system is based on modern technology with extensive Remote Monitoring and Maintenance capabilities, and very high reliability and integrity. To meet this objective, the monitor
comparator and station control are based on digital hardware, while the RMS interface is
microprocessor based.
3.2
Physical Description
The cabinet contains three sections:
• The electronics card cage
• The change-over section
• The transmitter / PA section
The electronics card cage contains the RF oscillators, the LF signal generators, the monitors,
SYSTEM DESCRIPTION

NORMARC 7033
GENERAL DESCRIPTION
INSTRUMENT LANDING SYSTEM
the station control, the RMS processor, and the voltage regulators.
The change-over section contains coaxial relays, attenuators and phasers for the RF outputs.
The transmitter / PA section contains the PA blocks including couplers etc. for each output.
The cabinet is divided in two parts, with the rear part fixed to a wall, and the front part hinged
to give access to interior of the cabinet.
All external connections are made to the rear part of the cabinet.
3.3
Monitors
The ILS has duplicated monitors with inputs for Course Line (CL), Displacement Sensitivity
(DS), Near Field (NF), and Clearance (CLR) (Dual Freq. only). The signals are detected by
the input stage, and then digitized. In the next block they are filtered by a Fast Fourier Transform performed by a signal processor. The results for each parameter is then compared with
stored limits in a digital hardware comparator.
Each of the two monitors consists of two modules. For Cat III use, Hot Standby monitoring can
be added by using one additional monitor and associated RF couplers and combiners.
The design of the monitors ensures a very high integrity due to the use of digital hardware for
the alarm comparators and a very simple Fast Fourier filtering with a signal processor. In addition, the monitor is checked by automatic self-tests.
The alarm limits are stored locally in EEPROM, and can be updated from the RMS processor,
with a separate hardware write protection to ensure that the integrity is not affected by the
RMS system.
3.4
Transmitters / Modulators
The transmitters are duplicated, either single frequency or dual frequency. Each transmitter
consists of a RF oscillator, a LF generator, and one or two PA blocks (single or dual frequency).
The RF oscillator uses a synthesizer for easy frequency changes and simple logistics. The
oscillator has two outputs for use in dual frequency systems.
The LF generator contains the generators for 90Hz, 150Hz and 1020Hz signals, the ident
keyer / sequencer and interface for DME master or slave keying. All signals are generated by
division from a common clock oscillator, ensuring very stable phase relations between the
modulation signals.
The modulation balance, modulation sum, RF level and Ident morse code are set in this module by means of multiplying digital to analog converters. The values are stored locally in
EPROM and can be updated from the RMS processor with hardware write protection.
The same LF generator is used for single and dual frequency systems.
3.5
TX Control
The TX control unit controls the system dependent on alarms from the monitors and inputs

GENERAL DESCRIPTION
NORMARC 7033
INSTRUMENT LANDING SYSTEM
from the local control, the remote control and, optionally, the RMS system. It also generate
status information to the same units. The local control and status indicators are a part of the
TX Control unit.
All functions in the TX Control are based on digital hardware to ensure the highest integrity.
3.6
Remote Monitoring (RMS) Unit
The RMS unit contains the system microprocessor. It handles storage and read-out of monitor
parameters, measurements for maintenance and fault finding, and performs fault analysis to
isolate faults to line replaceable modules. It is also used to set monitor limits and transmitter
adjustments.
The RMM handles communication to local and remote RMS computers, and in addition it handles a small display and keyboard for parameter setting and readout.
3.7
Remote Control Unit
The remote control unit is used in the tower or in the technical control room. It has indicators
for operating status as well as detailed warnings and an aural alarm device with reset. It can
control equipment on/off and change-over, and has an Access Grant-switch to allow remote
control from the RMS system.
The Remote Control Unit is connected to the ILS by one telephone pair cable.
3.8
Remote Slave Panel
The slave panel is connected to the remote control by a multipair wire. It is intended for use in
the control tower. It has indicators for normal / warning / alarm and has an aural alarm device.
in addition it can turn the equipment on and off, and has an aural alarm reset.
Optionally a slave panel with remote control functionality can be delivered.
3.9
Remote Maintenance Monitoring (RMM)
The NM7000 series has a built-in Remote Maintenance Monitoring system. This system consists of the RMS system, remote PC terminals with the RMM program installed, and the local
keyboard/display. Figure 3-2 illustrates the RMM/RMS systems

The centre of the RMS system is a CPU with the RMS core program. The RMS collects measurements and diagnostic data, and makes them available to the user. The collected information allows easy and cost effective maintenance, fault finding and routine reporting. In
addition, system settings are distributed and parameter readings are collected via the RMS/
CPU.
External personal computers are used for a user-friendly interface to the RMM system. The
equipment has three serial output ports, typically used to connect a local PC, a PC in the airport technical equipment room, and a modem for connection to a central maintenance facility.
