GENERAL DESCRIPTION NORMARC 7033 INSTRUMENT LANDING SYSTEM 3 System description This chapter gives a functional overview of the NM70xx ILS systems. 3.1 Overview The complete ILS electronic system is housed in a compact, wall mounted cabinet. The cabinet and the electronics, except for RF units, are common to the LLZ and GP systems . Monitor input signals Monitor Transmitter Remote Control NAV signals out External sensors RMS TX control Comm.
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.
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.
