EHang Ground infrastructure

Prepare an EHang ground-equipment and infrastructure enquiry using the aircraft model, site scope and project technical brief.

Equipment and purchasing requirements

Distinguish a new-system enquiry from spare parts for existing equipment. The model, documentation and required contents define the purchasing scope.

Site and ground-system scope

EHang presents infrastructure solutions covering operating sites and ground support. Separate equipment procurement from construction and organisational work in the purchasing brief. Identify the aircraft model, the existing site and the equipment elements to be considered.

  • Aircraft model to be supported
  • Site purpose and location
  • Existing installed equipment
  • Boundary of the requested supply

Vertiport reference document

EHang publishes a vertiport standards document as an official reference. It can support an initial discussion with the project designer. For a purchasing enquiry, attach the agreed technical brief and a site-specific equipment list.

  • Reference document title and version
  • Designer’s technical brief
  • Equipment list for the actual site
  • Party responsible for technical requirements

Ground monitoring

EHang describes ground monitoring of aircraft status and routes. For a control-device enquiry, identify the model, software version and system contents. A new installation and replacement of a particular workstation have different supply scopes.

  • Control or monitoring device model
  • Installed software version
  • Existing system scope
  • Number of workstations requested

Charging and service area

Request site equipment through an itemised device list rather than a project name alone. Charging and service items need their own identifiers. At an existing site, include the labels of installed equipment and state what will remain in use.

  • Ground-device list
  • Existing charging-equipment labels
  • Equipment models served by the site
  • New site or expansion

Project responsibilities

Separate equipment, installation, configuration and operating arrangements in the enquiry. Identify the responsible project parties and the status of the technical documentation.

  • Equipment as an itemised list
  • Installation and configuration as separate activities
  • Parties involved in technical approval
  • Documents needed to accept the supply

Identify the exact product

Start with the complete EHang designation on the product identification plate. A commercial model name alone may not distinguish revisions in your records. A readable photograph links the enquiry to a particular aircraft or ground unit.

  • Full model including its letter suffix
  • Serial number from the identification plate
  • Production year recorded in your documents
  • Overall product photo and a close-up of its label

Locate the item in documentation

Attach the complete illustrated page when the required item appears in a diagram. A drawing position identifies its location; a part number identifies an orderable item or assembly in the relevant documentation. Keep the document title and revision visible.

  • Part number with all hyphens and leading zeros
  • Position number in the assembly drawing
  • Document title and revision
  • Quantity per aircraft and total requested quantity

Photographs for identification

A few targeted photographs are usually more useful for identification than a large set of distant views. Show the label, overall shape, installation location and accessible interfaces. Use photographs already available from normal maintenance.

  • Label without glare or obstructing objects
  • Overall view and installation location
  • Accessible mounts and connector faces
  • File names identifying model, assembly and side

Electrical configuration

For an electrical unit, provide the information printed on that unit rather than relying only on the aircraft name. Similar enclosures do not establish an electrical match. The original connection diagram and the names of connected equipment help define the enquiry.

  • Unit designation and label revision
  • Rated values exactly as marked
  • Photographs of accessible electrical interfaces
  • Diagram from the documentation for your equipment

Battery assembly enquiry

Treat a battery enquiry as a request for a specifically identified assembly. State whether the scope is a complete battery, a documented accessory or a charger. Record the label and the equipment with which it is used.

  • Battery assembly model
  • Label of the existing charging equipment
  • Scope listed in the current specification
  • Number of assemblies and delivery destination

Mechanical parts and assemblies

Clarify which level of a mechanical assembly you need. An individual fastener, a housing and a complete installed unit should be separate enquiry lines. If a drawing is available, retain its number and revision.

  • Assembly name and installation location
  • Drawing number or illustrated position
  • Left or right side where documented
  • Individual item or complete kit required

Ground equipment

Separate the aircraft from ground equipment in the enquiry. Charging, control and service equipment should have their own model and identification details. For a new project, list the equipment you already own.

  • Ground unit model
  • Equipment that connects to it
  • Contents of the existing system
  • New installation or replacement of an existing unit

Software version and scope

For control equipment, include a screenshot showing the product name and the version of the installed software. A licence, a physical device and a configuration service are different purchasing items. List them separately and identify which ones are actually required.

  • Installed software name and version
  • Device on which it is used
  • Hardware, licence or both requested
  • Supply scope from the existing equipment list

Describe the service requirement

A symptom description helps define an enquiry when the part number is unknown. Identify the assembly named in your documentation and the normal operating stage at which the issue was observed. Attach an existing maintenance report when available.

  • Assembly name from the documentation
  • Short description of the observed symptom
  • Message code without credentials or private access data
  • Available report from the maintenance provider

Replacement or expansion

State whether the purchase is intended to restore an existing system, replenish spare stock or expand a fleet. Each requires a different comparison. An installed item is the reference for replacement, while a new project starts with the required function and a technical brief.

  • Replacement, spare stock or a new project
  • Exact item in the existing configuration
  • Functions that must be retained
  • Alternatives specifically requested by the customer

A multi-line enquiry

Use one row per item for a list of spare parts. Repeat the aircraft or ground-equipment model on each row when the fleet contains different configurations. Link photographs and catalogue pages to the relevant row number.

  • Line number, description and part number
  • Equipment model and quantity
  • Reference to an attached file or page
  • Purchasing priority for that item

Requested supply documentation

List the documents your organisation requires to review a proposal and perform incoming inspection. Distinguish product identification from requirements concerning origin, completeness and operation.

  • List of requested accompanying documents
  • Incoming inspection requirements
  • Required documentation language
  • Reference to the relevant purchasing specification clause

Check the assembly scope

The word kit does not define what is included. For each assembly, list the accessories required by your documentation and identify the existing items that you intend to retain. When reviewing a proposal, compare both the part number and the contents of each line.

  • Main item and separate accessories
  • Quantity of each element in the kit
  • Items retained by the customer
  • Requested packing and contents list

Packing and delivery destination

Provide the delivery destination and any receiving constraints in the initial enquiry. For larger equipment, access, unloading and storage arrangements can affect planning. Separate packing requirements for the main equipment from those for sensitive components.

  • Destination city and country
  • Unloading and warehouse access constraints
  • Packing requirements in your specification
  • Single consignment or separately requested shipments

Compare purchasing options

Compare proposals against the same scope. One option may cover an assembled unit while another covers only a component or a basic configuration. Keep the equipment model, accessory list and documentation requirements in the comparison table.

  • Same model and required function
  • Main assembly and accessory contents
  • Quantities and units of measure
  • Documentation and acceptance requirements

Prepare incoming inspection

Identify who will check the delivered equipment and documentation on the customer side. For spare parts, prepare a list of identifiers and quantities from the agreed specification. For a complete system, include separate devices and accessories.

  • Person responsible for checking delivery scope
  • Identifiers from the agreed specification
  • Packages and contents listed in the documents
  • Procedure for recording discrepancies on receipt

Documents and sources

Prepare the specification

Use one line per item: model, part number, quantity and attachment reference. For a project, describe the task and list equipment already available.

Enquiry conditions

Availability, price, lead time, scope and documentation are determined for the specific enquiry. Dealer status, authenticity and compatibility are not assumed. Operational approvals require assessment by the responsible specialists for the particular project.
