GPS 400W WAAS GPS navigator 011-01057-40

011-01057-40 is the exact Part Number for this Garmin GPS 400W WAAS GPS navigator. The unit provides IFR GPS/WAAS navigation and route guidance without an integrated VHF communication or VOR receiver. This card is tied to the photographed configuration and its exact suffix; it is not a generic listing for every GPS 400W variant or for a visually similar member of the same product family.

The source listing identifies Part Number 011-01057-40 as a black-bezel GPS 400W with WAAS upgrade, Jeppesen database capability and 14/28 V operation. The authentic rear plate confirms the exact GPS 400W model, Part Number 011-01057-40, 14/28 V DC supply and photographed serial number 96700433. These identification details are retained because software level, voltage, bezel, lighting, options and certification can vary across related versions. The Part Number, installed configuration and approved technical data should therefore be checked together before purchase or installation.

Operational role and capabilities

The GPS 400W calculates position and navigation guidance, presents route and map data, and can drive compatible navigation indicators or exchange information with other approved avionics. Its role is focused on satellite navigation, so a complete panel may use separate communication and conventional navigation equipment. The unit must operate as part of a complete approved avionics installation. It cannot replace missing antennas, sensors, data sources, indicators, control equipment or aircraft wiring, and the availability of a feature on the faceplate does not by itself prove that the feature is enabled in a particular aircraft.

The practical value of GPS 400W is its ability to place the required function within direct reach of the crew while exchanging the necessary signals with compatible equipment. Correct operation depends on serviceable power, grounds, antennas, data buses, circuit protection, cooling where required and configuration settings. A fault reported at the unit can also originate elsewhere in that connected chain, so troubleshooting should follow approved maintenance procedures.

Installation and connected equipment

Approved installations can include the GPS antenna, main power and ground, lighting, altitude data, external GPS/VLOC annunciation as required, a compatible CDI or HSI, and serial or ARINC 429 interfaces. Integration with transponders, autopilots or multifunction equipment depends on approved wiring and software configurations. The rack, backplate, connector kit, antenna, wiring and accessories are not assumed to be included unless they are expressly identified in the quotation. Even when two units share a common panel size, their connector keying, pin allocation, software, power requirements and approval basis can differ.

Before installation, technicians should compare 011-01057-40 with the removed unit, aircraft equipment list, wiring diagrams, installation manual and modification records. They should also confirm available panel space, mounting depth, connector condition, antenna compatibility, circuit protection, lighting, cooling and interface configuration. Any substitution requires approved data; similarity of model names or photographs is not evidence of interchangeability.

Configuration checks for 011-01057-40

The complete suffix in 011-01057-40 is an essential part of the product identity. Database status, embedded options, software level, modification status and certification may affect compatibility even when the hardware looks unchanged. These points are especially important when replacing legacy avionics in an aircraft that has accumulated field modifications or multiple supplemental approvals during its service life.

Incoming inspection should verify the manufacturer plate, housing, connectors, locking mechanism, controls, display or indicator face, cooling provisions and evidence of unauthorized modification. Functional testing should use the approved bench procedure for this model. Installation and return to service remain the responsibility of appropriately authorized personnel working to the aircraft and equipment documentation.

Serviceable condition, ordering and support

This 011-01057-40 GPS 400W is offered in Serviceable condition from partner stock with a six-month warranty. Stock status means that availability is based on a partner-held position and should be reconfirmed when a quotation is requested. The allocated serial number, current test status and documentation available for the specific unit are confirmed before order acceptance.

For an inquiry, specify Part Number 011-01057-40, model GPS 400W, required quantity, destination and any installation or documentation requirements. Include the aircraft type and the Part Number of the unit being replaced when possible. Related avionics can be reviewed in the Garmin / BendixKing / Honeywell / Collins category. Products shown together there may be functionally connected, but they are not presented as interchangeable unless approved technical data explicitly authorizes the substitution.
