# Manufacture of configured civil battery-electric quadrotor aircraft

## 1. Scope and Applicability

Manufacturing foreground of a new complete configured civil battery-electric quadrotor assembled from supplier-complete carbon-composite body/arm/gear, brushless propulsion, onboard control/power/radio modules and one declared supplied flight battery. The selected bolted/preconnectorized modular route is narrower than all CPC49624 aircraft. Existing battery, motor, wiring and camera PCRs concern upstream products, not complete aircraft integration and net acceptance. No existing material complete civil quadrotor PCR was identified. The Holybro X500v2 manufacturer and version-pinned PX4 build guide supply an assembly example, not an observed current plant inventory or finished-aircraft weight. The kit itself is not the complete accepted output; actual completion, battery and equipment must be established independently. Exclude military products, fixed-wing/hybrid/combustion/fuel-cell/other rotor-count routes, airframe/component manufacture performed by suppliers, incomplete kits, loose parts, repair-service products and refurbishment. Customer missions, agriculture/crop output, mapping services, flight-hour/payload-distance function, ground infrastructure, lifetime and disposal are outside; actual manufacturing tests/rework are inside their measured boundary. Candidate authored methodology awaits independent scientific review.

## 2. Product Category Identity

| Field | Value |
| --- | --- |
| canonical_pcr_id | pcr.metal-products-machinery-and-equipment.transport-equipment.civil-unmanned-aircraft |
| classification_refs | CPC 3.0 49624; narrower semantic candidate; no accepted mapping |
| covered_products | Complete accepted configured modular civil battery-electric quadrotor with supplied installed flight pack |
| excluded_products | Other aircraft routes, military products, kit/loose parts, ground equipment and use/service/repair |
| representative_product | X500v2 prewired four-arm architecture with actual complete configuration and battery separately established; no catalogue weight adopted |
| production_route | Mechanical module assembly; onboard electronic integration/configuration; conditional local repair; supplied-pack installation/testing; complete calibration/mass acceptance; actual packaging |
| market_state | New complete accepted civil aircraft at declared factory gate |

## 3. Reference Flow

| Field | Value |
| --- | --- |
| What | Manufacture of one complete configured civil battery-electric quadrotor |
| How much | 1 kg accepted net complete unit; actual verified M kg per accepted aircraft |
| How well | Meet current approved mechanical fastening/rotor match, wiring/power polarity, firmware/sensor orientation/calibration, control/radio and battery acceptance plan, preserving actual inspection/test results. No invented tolerances, flight endurance or legal conformity |
| How long or cycle | One manufacturing delivery; no mission/flight-hour/battery-cycle lifetime unit |
| reference_flow_link | `finished_aircraft` |

| Field | Value |
| --- | --- |
| Reference amount | 1 |
| Reference product flow | Unmanned aircraft `295f8826-57a5-481c-8214-909e14c5a14b` |
| Reference flow property | Mass `93a60a56-a3c8-11da-a746-0800200b9a66` |
| Reference unit group | Units of mass `93a60a57-a4c8-11da-a746-0800200c9a66` |
| Reference unit | kg |
| Required qualifiers | Model/serial; four-rotor geometry/rotation and actual body/arm/gear/module drawings; complete BOM/make-or-buy inclusion; motor/ESC/propeller matching; controller/firmware/actuator mapping and communication equipment; flight-pack chemistry/cell format/series count/capacity/connector/protection, actual supplied and installed mass/state of charge; declared installed payload; site/period/test plan; calibrated complete net M kg and independent module balance; excluded ground controller/charger/spares/packaging; matched upstream/transport/receiver links |

Declare all qualifiers in metadata or equivalent notes. Broad public Mass aircraft identity is narrowed to the actual configured civil quadrotor and supplies no flight-function equivalence.

## 4. Measurement and Unit Rules

| rule_id | Applies to | Required property | Required unit | Rule |
| --- | --- | --- | --- | --- |
| `reference_mass` | reference product | Mass `93a60a56-a3c8-11da-a746-0800200b9a66` | kg | M = accepted net mass of one complete unit of the same configuration in kg; collect using cp_mass. |
| `electric_energy` | electricity rows | Net calorific value `93a60a56-a3c8-11da-a746-0800200c9a66` | MJ | Read actual stage AC energy;1kWh=3.6MJ. Charger input already contains actual conversion/test losses; do not add theoretical battery capacity or unmeasured recharge cycles. |

## 5. System Boundary

Start at actual supplied independently scoped body/arm/gear and electronic/flight-pack module receipts at plant. End at complete configured manufacturing acceptance, including actual associated packaging work while excluding its mass from M. Include actual bolting/rotor installation, module wiring/configuration, battery installation and measured testing, sensor/control checks, trial/rework and conditional localized repair. Supplied prewired arms include motor/ESC/wiring once: simultaneous separate arm/motor/ESC/raw carbon inputs or upstream resin cure would duplicate the supply boundary. Local PCB/SMT, motor winding, cell/pack manufacture, composite fabrication or extensive fabrication would require another explicitly expanded boundary, not a claim that these occur here. Base example requires no local soldering; optional repair consumptions/emissions need actual approved records. Expand actual missing retaining straps, mounts, radio antennas, vibration pads, companion computer, protection equipment, test fixtures/service, return shipments, charging interfaces and each packaging component before claiming complete coverage. External suppliers, extraction, inbound transport and receiving waste treatment are covered only through independently matched datasets; no complete cradle-to-gate claim without links. Customer flight/agricultural output/service and ground systems remain outside.

### Boundary Abstraction

| Field | Value |
| --- | --- |
| declared_starting_condition | At-plant supplied prewired structural/propulsion and onboard electronic/battery modules |
| starting_condition_role | boundary_abstraction |
| product_classification_scope | Complete modular civil battery-electric quadrotor; narrower CPC49624 |
| recursive_input_rule | Purchased complete aircraft is a distinct receipt and changes the final-manufacturing boundary; do not recursively duplicate its contained modules or supplier operations |
| upstream_dataset_requirement | Match actual module geometry/material/chemistry/complete gate, wiring/voltage/provider geography, battery state/protection and receiver route |
| disclosure | Manufacturing integration foreground only; disclose actual supply inclusion, unresolved identities, current BOM/measurement/test and missing links |

### Boundary Rules

| rule_id | applies_to | rule | source_ids |
| --- | --- | --- | --- |
| `boundary_supplied` | assemblies | Document supplied completeness and independently measured module kg, included fluid/charge/hardware and installed count. The actual preassembled arm replaces its internal motor/ESC/lead receipts. Separate any supplier-complete frame/gear/holder inclusions before counting those split cards. | holybro-x500-v2 |
| `boundary_tests` | acceptance | Include actual ordered factory firmware/calibration/actuator/radio/charge and performed acceptance flight work with measured supply energy, fixture/service and rework. Actual rotor removal/test payload must be recorded and corrected physically for complete M; no customer mission or nominal flight-time proxy. | px4-x500-v114 |

## 7. Allocation and Co-product Handling

| rule_id | applies_to | rule | source_ids |
| --- | --- | --- | --- |
| `allocation_direct` | shared assembly/test | Subdivide orders/configurations and meters before allocation. Demonstrated actual station/test occupancy, measured tool/test/charger demand and causal time records may attribute shared work; aircraft count or kg alone is not a universal driver. Retain idle/rework/rejected trials, raw period totals and accepted same-configuration denominator with sensitivity. Source build-time claims are not labour/energy allocation factors. |  |
| `allocation_recovery` | returns/waste | Track supplier returns, repair/reuse, solvent recovery and measured disposal as separate destinations. For actual valuable co-products use subdivision/causal relations first and disclose alternative allocation and sensitivity when unavailable. Do not infer recycled-battery/fibre credits, recovered-IPA yield or avoided electronics production. |  |

## 8. Foreground Data Collection, Calculation, and Quality Rules

### Data Collection Protocols

| protocol_id | process_id | flow_role | record_type | raw_fields | collection_method | unit | frequency | temporal_coverage | site_scope | aggregation_rule | quality_evidence |
| --- | --- | --- | --- | --- | --- | --- | --- | --- | --- | --- | --- |
| `cp_mass` | acceptance | reference product | calibrated complete-aircraft weighing | model; configuration; serial; accepted net mass M; calibration/zero/tare; installed battery/payload/rotors; state corrections and independent module balance | Weigh the accepted complete unit on a calibrated scale, excluding transport packaging; reconcile the same configuration and acceptance record. | kg | each accepted aircraft/configuration change | declared representative current production period | named actual manufacturing site | accepted net mass per unit | calibration/raw net readings and independent installed module mass |
| `cp_parts` | all_processes | single supplied assembly | receipt and installed component record | one assembly/design/material/chemistry/serial/count; supplied and installed net kg; inclusions; return/reject; accepted count | Measure separately supplied/installed module kg, preserving count/serial and supplier inclusions. Reconcile preassembled arm, motor/ESC and battery internals once with whole-aircraft M; do not replace kg with item counts or catalogue weights. | kg | each lot/design and accepted order | declared representative current production period | named actual manufacturing site | actual installed supplied kg / accepted units of the same configuration | supplier BOM/serial, calibrated net receipt/installed weights and closure |
| `cp_stock` | all_processes | single formulation or box | issue/return and repair/packing record | single chemical/alloy/formulation or box design; lot/SDS; issues/returns; retained amount; residue/recovery; accepted count | Weigh actual net issues/returns and retention for each one defined repair formulation or shipping box. Preserve solder alloy/flux scope and cleaner actual concentration; box and loose accessories are outside net M. No nominal mix/yield or implied repair occurrence. | kg | each lot/repair/dispatch period | declared representative current production period | named actual manufacturing site | actual attributable stock kg / accepted units of the same configuration | scale/tare, SDS/alloy certificate and joint/packing balance |
| `cp_energy` | all_processes | single AC supply interface | meter and causal stage attribution | meter/site/provider/voltage; actual imported kWh; stage/charger/test/idle/rework; accepted count | Read calibrated meters and attribute actual assembly/configuration/repair/charge/test/packing demand with causal records. Convert kWh to MJ using1kWh=3.6MJ. Preserve charger interface, initial/final pack charge and actual test energy; nominal capacity is not metered input. | MJ | each stage/test batch and period | declared representative current production period | named actual manufacturing site | actual attributed stage MJ / accepted units of the same configuration | meter calibration, cycle records/provider boundary and energy reconciliation |
| `cp_waste` | all_processes | one physical waste stream | segregated receiver shipment | single waste chemistry/complete module/serial/state; actual net kg/tare; source and receiver; recovery/return; accepted count | Weigh actually exported segregated waste excluding containers and retain receiver and analysed state. Separate solder residue, spent cleaner, complete controller and complete rejected flight pack; supplier repair return is not assumed disposal. | kg | each shipment/period | declared representative current production period | named actual manufacturing site | actual exported net waste kg / accepted units of the same configuration | scale/tare, analytical/serial and receiver/source balance |
| `cp_emission` | repair | single residual IPA air release | compound-specific measurement | CAS67-63-0; actual air submedium; post-control concentration/flow/time; limits/uncertainty; solvent balance; accepted count | Quantify actual post-control residual isopropanol by matched sampling or documented closed solvent balance resolving recovery/residue/retention. Distinguish absent, not measured and below detection; none automatically means zero or complete evaporation. | kg | representative actual repair/control period | declared representative current production period | named actual manufacturing site | actual released kg / accepted units of the same configuration | sampling/lab calibration, actual operation and solvent mass balance |
| `cp_configuration` | all_processes | complete delivered aircraft | as-built/firmware/test acceptance record | serial/model; full BOM/module inclusions; battery/payload and rotor state; firmware/calibration/actuator mapping; performed tests/repair; delivery exclusions | Trace actual controlled as-built drawings/BOM, supplied completeness, wiring/firmware/configuration and ordered inspection/test/repair results.

### Calculation Rules

| rule_id | Applies to | Formula or rule | Inputs | Output | source_ids |
| --- | --- | --- | --- | --- | --- |
| `normalize_mass` | all inventory rows | q_ref = q_item / M; q_item = exchange amount per one accepted finished unit; q_ref = exchange amount per 1 kg reference flow. | q_item; M; cp_mass | q_ref |  |
| `period_conversion` | order records | Attribute measured period totals to one same accepted configuration using documented causal records, then obtain q_item from attributed exchange / accepted aircraft. Retain raw totals, accepted denominator and rework/reject burden; do not pool unlike battery/payload/module configurations without an explicit weighted physical model. | cp_parts; cp_stock; cp_energy; cp_mass | q_item |  |

### Data Quality Requirements

| requirement_id | Applies to | Requirement | Evidence |
| --- | --- | --- | --- |
| `mass_provenance` | cp_mass | Positive M must originate in current actual calibrated net weighing of the accepted same-serial complete configuration, with original readings, scale capacity/resolution/calibration, zero/tare, supports and uncertainty. Reconcile independently measured installed module/retained consumable mass with complete-aircraft M. If the actual safe test/weighing state removes battery or rotors, retain the actual original state and separately measured signed same-unit add/remove corrections; no guessed correction. No kit/frame weight, takeoff/payload limit, shipping weight or battery capacity-to-kg estimate establishes M. | cp_mass; cp_parts; cp_configuration |
| `net_configuration` | accepted aircraft | M includes the actual complete accepted airframe, four installed rotor/propulsion assemblies, permanent onboard power/controller/GNSS/radio/harness and the specified supplied installed flight battery once; declare and reconcile actual payload/protection equipment. Exclude ground controller, external charger, test leads/fixtures, loose spare battery/propeller, transport packaging and temporary test payload. Supplied battery cell electrolyte/hardware and arm motor/ESC/wiring are included once, without duplicate separate receipts. Record charge state and actual delivery configuration, not nominal endurance. | cp_mass; cp_parts; cp_configuration |
| `route_and_balance` | all exchanges | Current full as-built BOM, make-or-buy inclusion and controlled assembly/firmware/acceptance plan determine observed exchanges. Prewired base route does not require local solder/flux/cleaner; optional repair requires actual joint/SDS records. Expand all missing specific mounts/straps/antennas/pads/protection/payload/computing, supplied interfaces, packaging and receiver/transport/test-service links before completeness claims. Check stock-to-installed/return/reject/residue balances, charger energy and chemistry-specific emissions, with limits/uncertainty and allocation sensitivity. Do not infer battery cycle life, rejection fractions, composition or charging efficiency. | cp_parts; cp_stock; cp_energy; cp_waste; cp_emission; cp_configuration |
| `source_limits` | external evidence | Holybro manufacturer snapshot describes a kit with preinstalled arm motors/ESCs and optional payloads, not a finished measured aircraft or a complete production inventory. PX4 v1.14 guide documents mechanical/electrical integration and model-specific setup; it shares the Holybro hardware and does not constitute independent quantitative observations. Do not adopt advertised build time, frame mass, hover time, battery capacity/voltage, software defaults or screw counts as manufacturing factors, universal acceptance criteria, lifetime or current legal mandates. Collect current actual plant and product records independently. | holybro-x500-v2; px4-x500-v114 |

## 9. Validation Rules

| rule_id | applies_to | rule | source_ids |
| --- | --- | --- | --- |
| `validation_reference` | reference_flow | Verify complete configured civil electric quadrotor, actually installed supplied battery/payload scope, positive physical M kg and independent mass_provenance/net_configuration. Reference selected flow equals finished_aircraft; generic aircraft identity supplies no battery weight or payload-function equivalence. |  |
| `validation_route` | all_processes | Check actual supplied arm/frame/gear/module inclusion, matched rotor/ESC/controller and real wiring/firmware/calibration/charge/test records. Preserve order and performed optional repair/cleaning state; compare full BOM/physical weights and stage stock/energy/waste balances. Current lawful civil/type requirements are a separate actual compliance question, not inferred from this example. | holybro-x500-v2; px4-x500-v114 |
| `validation_identity` | all flow rows | Verify actual type/substance/reference property/unit group, supplied module completeness, chemistry/voltage/state/medium and official bilingual names. Collection-category purchased UAV parts/avionics do not replace atomic modules; industrial robot drive is not a preassembled drone arm. Preserve battery Number/Energy identities rather than rewriting them as Mass; a valid conversion would require actual matching pack and physical records. IPA is not chloropropanol or n-propanol; contained solvent/PCB residue is not an elementary air release. Keep exact unresolved row_ids. |  |
| `validation_claims` | claims | PCR mechanical pass is not independent scientific approval, current civil-aircraft legal/type conformity, observed complete factory inventory, actual measured weight or mission/lifetime equivalence. Broader claims require complete current supplier/BOM/measurement/test/linked evidence and disclosed remaining gaps. |  |

| dataset_role | Configured modular civil electric quadrotor manufacturing integration foreground; heading does not assert publication |
