EFIS processing and display relationship

In an approved EFS 40/50 installation, the SG 465 processes data for electronic attitude, horizontal-situation and supported multifunction presentations. Depending on the system configuration, one or two compatible display units and a suitable control panel may be connected. The precise pages, overlays and annunciations are determined by aircraft interfaces, software and the approved control arrangement.

A simplified path is attitude, heading, navigation, flight-guidance, radio-altitude or weather-radar source → SG 465 input processing and symbol generation → compatible ED-series display → crew. The generator monitors selected inputs and can command failure annunciation when processed data is invalid. It does not create reliable flight information when an upstream source or data bus is missing.

Exact -1113 identification and software plate

The authentic plate identifies the unit as an SG 465 Symbol Generator with Part Number 066-04021-1113 and serial number 4900. It shows TSO C113, RTCA/DO-160B and DO-178A Level 1 / Level 2 references. The separate software label reads SW MOD 13/01. These exact markings are retained for technical comparison and must not be generalized to another suffix.

The housing is a tall remote-mount unit with metal rails and lower mounting brackets. Exact dimensions, weight, electrical supply, connector type and detailed input/output allocation were not independently confirmed from authoritative open documentation for this -1113 suffix. Those values should be taken from the approved SG 465 installation manual and aircraft wiring data, not inferred from another SG 465 version.

Installation, cooling and configuration checks

Before installation, verify Part Number 066-04021-1113, software modification 13/01, equipment rack, connector keying, cooling, power supply, aircraft data buses, connected ED display type, control panel and all enabled sources. SG 465 configurations may support different display sizes and system functions, making the approved software and wiring definition as important as the physical enclosure.

Functional testing should confirm valid display generation, source selection, attitude and navigation presentation, mode annunciation and response to invalid inputs. A display complaint can originate in the SG 465, ED display, source sensor, control panel, wiring, cooling or power. Technicians should isolate the complete chain rather than automatically condemn the symbol generator.

The -1113 unit must not be treated as a direct substitute for a later WAAS-related SG 465 suffix. Software upgrades and Part Number conversions can require approved modification data, interface changes or additional annunciation. Similar mounting rails do not authorize substitution. The serial-numbered unit's release documentation should record its actual modification and software status.

Overhauled supply and ordering information

This 066-04021-1113 SG 465 is offered in Overhauled condition from partner stock with a six-month warranty. The price follows the specific offer because no exact same-condition public price requiring a higher value was confirmed. The quotation will identify the allocated serial, overhaul source, software modification, current test status and release certificate.

For an inquiry, specify Part Number 066-04021-1113, model SG 465, aircraft type, EFS 40/50 configuration, connected ED display, software requirement, quantity and certification. Displays, control panels, sensors, rack, connector and wiring are supplied only when expressly included.
