Define an EHang drone-show equipment or spare-parts enquiry by aircraft model, fleet scope and control-system requirements.
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.
Aerial Media product direction
EHang light shows involve coordinated drone fleets. An enquiry for a performance fleet differs from purchasing a passenger or cargo aircraft. Specify whether the scope is a new system, expansion of an existing fleet or spare parts for an identified drone.
Manufacturer direction: Aerial Media
Coordinated fleet management
Synchronised light-show performance
Identify every device model in the purchasing scope
RTK-GNSS positioning
EHang identifies RTK-GNSS in its description of formation-show positioning. Define the positioning equipment through the system specification when requesting a package. The technology name alone does not identify a device model, accessory list or integration requirements.
System contents from documentation
Ground-equipment model
Existing software version
New fleet or expansion of an existing fleet
Fleet scope
State the number of aircraft requested and the contents of any existing fleet. List reserve aircraft, battery assemblies and accessories separately. A complete item list makes proposals comparable and avoids treating the headline drone count as the entire system.
Main and reserve aircraft quantities
Models of equipment already owned
Battery assemblies requested
Accessories and ground devices
Light modules and spare parts
Identify show-drone spare parts using the aircraft model and label. For a light module, provide the assembly identifier and documented contents. When several different components are requested, link each photograph to its own enquiry line.
Show-drone model
Required module label
Technical parts-list position
Quantity and required assembly contents
Equipment and show preparation
Separate equipment procurement from the organisation of a particular performance. Hardware enquiries need model and scope details; a project brief needs the task, site and responsible parties.
System purchase or spare-parts enquiry
Existing equipment scope
Documentation and completeness requirements
Separate list of any other project services requested
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.
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.
