Single-aisle twin-turbofan civil passenger aeroplane final assembly

1. Scope and Applicability

Candidate authored methodology for new complete single-aisle, twin-high-bypass-turbofan civil passenger aeroplane final assembly. The actual aircraft unladen classification exceeds2000kg, supported by original configuration/weight records. Receive completed equipped supplier airframe sections and wings, integrate declared propulsion/systems and complete customer cabin, perform actual paint and attributable production acceptance, then release at the declared delivery gate. The example Airbus process does not establish a universal aircraft architecture or all-site route.

This is narrower than CPC49623. Exclude widebody aircraft, rotorcraft, unmanned aircraft, piston/turboprop/turboshaft or other propulsion aircraft, bare sections, separately sold engines, partial-cabin development aircraft, conversions, repairs, military-specific aircraft and operating passenger transport. Type-development certification/fatigue campaigns are not automatically series manufacturing acceptance. Aircraft wiring and piston-engine PCRs describe independent upstream products, not this complete aircraft. Scientific review is pending; bilingual alignment and automated checks do not establish methodology approval.

Field	Value
Reference amount	1
Reference product flow	Accepted complete single-aisle twin-turbofan civil passenger aeroplane
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	producer/type/model and serial; current drawing/BOM and complete passenger cabin layout; twin high-bypass aircraft turbofan route, engine/nacelle/APU serials and supplier inclusion; equipped airframe section/wing/tail interfaces, landing gear and fitted systems; actual paint/SDS/abatement; actual accepted configured empty net M kg and cp_mass, original calibrated complete-aircraft weighing and signed measured configuration/fluid corrections; retain required installed equipment and declared permanent ballast, operating oil/hydraulic fluid and documented unusable fuel; exclude usable fuel, crew/passengers, cargo, temporary ballast/test instruments, packaging and loose spares; original actual unladen category above2000kg; actual site/period, test ground/flight subcompartment, outsourcing and delivery gate

Declare every required qualifier in dataset metadata or equivalent source-addressable fields. Equal mass does not imply equal seating, thrust, performance, environmental intensity or transport service. No catalogue empty weight is adopted as M.

4. Measurement and Unit Rules

rule_id	Applies to	Required property	Required unit	Rule
reference_mass	reference product	Mass	kg	M = accepted net mass of one complete unit of the same configuration in kg; collect using cp_mass.
exchange_mass	non-electric inventory rows	Mass	kg	Measure each net physical exchange separately. Count-based supplier statistics require actual measured unit mass or serial assembly weighing; preserve an adopted public count/area property if a compatible identity is later demonstrated, with an explicit supported conversion rather than rewriting it to Mass.
electric_energy	electricity_airframe; electricity_systems; electricity_propulsion; electricity_cabin; electricity_coating; electricity_acceptance; electricity_protection	Net calorific value	MJ	Actual process electricity kWh × 3.6 MJ/kWh; match supply geography/voltage/mix and preserve the public reference energy property. Allocate shared grid/ground-power consumption once with measured drivers.
species_mass	xylene_air; co2_air; no_air; no2_air	Mass	kg	Use exact measured chemical species, source and receiving medium; integrate actual concentration and exhaust flow on compatible state/time bases. No mandatory emission or default factor.

rule_id	Applies to	Required property	Required unit	Rule
mass_record_origin	cp_mass	Mass	kg	Use original actual complete-aircraft calibrated platform/ramp-wheel or load-cell weighing, following the current applicable aircraft manufacturer procedure. Retain all support readings, tare/zero/calibration and repeatability, clean indoor/level state, equipment list and serial configuration; measured signed additions/removals reconcile the accepted net M. Acceptance records are the collection interface, not a substitute for physical measurement. Nominal operating empty weight, maximum take-off weight, payload, design estimate or fuel-full value cannot substitute. Sources: faa-weight; faa-addendum
mass_configuration	cp_mass; finished_machine	Mass	kg	Retain delivered engines, complete cabin, gear, fitted systems, declared permanent ballast and specified operating oil/hydraulic-fluid and unusable-fuel state. Exclude usable fuel, people/cargo, temporary ballast/instrumentation, removable protection and loose spares. Measure quantities and densities at actual temperature/state for any fuel/fluid correction, never copy handbook example densities. Record separately potable water/lavatory charge excluded from this empty reference. Reconcile current manufacturer definition and delivery changes to weighing state; unmeasured corrections block completion. Sources: faa-weight

5. System Boundary

Boundary Abstraction

Field	Value
declared_starting_condition	Received supplier-completed equipped airframe sections, wings and separately supplied finished modules at final assembly
starting_condition_role	foreground_input_boundary
product_classification_scope	Narrow single-aisle twin-turbofan civil passenger aircraft portion of CPC49623
recursive_input_rule	Do not recursively assume every upstream supplier process inside the final-assembly gate
upstream_dataset_requirement	Link applicable complete supplier-section/module, actual consumable, energy, transport, subcontract coating and waste-treatment datasets before a cradle-to-gate claim
disclosure	Foreground final assembly, acceptance and release only; upstream completion, omissions and gate explicitly disclosed

rule_id	Applies to	Rule	source_ids
boundary_trials	acceptance	Include actual manufacturing acceptance ground runs/taxi and production acceptance flights attributable to this serial within the declared gate. Distinguish aircraft fuel, outside ground-equipment fuel and purchased test service. Certification campaign, commercial operation and post-gate ferry are excluded; any different gate needs separate documented scope.	airbus-assembly
boundary_completeness	dataset	This gate is not complete cradle-to-gate by itself. Inventory cards are exact conditional physical exchange examples; enumerate every actual separately supplied material/module/chemical, external heat/gas/test service, packaging, waste and measured release. Disclose omitted or unmeasured links without generic category rows, invented zeros or claims of complete coverage.

6. Process Inventory Structure

Process Map

process_id	process_name	inclusion	inclusion_condition	role	quantitative_reference
airframe	Equipped airframe section joining	required	Actual final assembly of the declared single-aisle civil passenger jet.	foreground	one accepted complete unit normalized with M
systems	Landing gear and aircraft systems integration	required	Each declared complete aircraft configuration.	foreground	one accepted complete unit normalized with M
propulsion	Turbofan and auxiliary-power installation	required	Declared twin-turbofan passenger jet with its actual auxiliary-power configuration.	foreground	one accepted complete unit normalized with M
cabin	Complete passenger cabin fit-out	required	Complete accepted customer passenger layout, not a partially furnished development aircraft.	foreground	one accepted complete unit normalized with M
coating	Conditional exterior cleaning and painting	conditional	Actual painting and cleaning included at the reporting final-assembly gate or disclosed subcontractor.	foreground	one accepted complete unit normalized with M
acceptance	Configured weighing and attributable acceptance	required	Each complete aircraft accepted at the declared delivery gate.	foreground	one accepted complete unit normalized with M
protection	Conditional delivery protection	conditional	Actual separately consumed temporary covers at the declared factory delivery gate.	foreground	one accepted complete unit normalized with M

Equipped-section joining feeds gear/systems, propulsion and complete-cabin integration; actual painting and acceptance precede factory release. Declare actual station order and subcontract boundary. Required stages do not make each example exchange compulsory: conditional chemistry or separately supplied modules require actual records; contained supplier constituents are counted once.

Process: Equipped airframe section joining (airframe)

Receive completed equipped airframe sections and wings, join with actual specified fasteners and seal joints. Declare section interfaces, installed systems and supplier inclusions. No upstream aluminium smelting, composite lay-up, section fabrication or wing manufacture is assumed inside this gate. The developmental A321XLR station sequence is an example, not a universal recipe.

7. Allocation and Co-product Handling

rule_id	Applies to	Rule	source_ids
allocation_orders	shared resources	Avoid allocation with subdivision and actual serial/order/station metering. Allocate residual shared resources by demonstrated causal measured joining machine-time, actual identical coating area and recipe, or attributable test/ground-power time and load, retaining numerator/denominator and sensitivity.

allocation_returns	chips; waste_paint; effluent	Distinguish net supplier returns, reusable tools/protection, internally retained material and transferred waste. Measure actual recipient/treatment state; no automatic avoided-primary-metal or fuel/recycling credit. A genuine coproduct requires separate reviewed causal allocation and matching upstream boundary, not inferred from sale alone.	ghg-allocation

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

Calculate actual attributable net exchange per accepted serial unit q_item after measured returns and stock changes and justified shared attribution, then divide by the same actual M. Compatible serial configuration aggregation uses total attributable exchanges divided by summed measured accepted net masses, with every serial retained. Separate airframe, engine, cabin, paint, gate and test routes that differ materially. Metered volume inputs require actual state/density to get kg; preserve original property and conversion uncertainty. Missing M, density, fossil share or measurement stays a gap.

Data Quality Requirements

requirement_id	Applies to	Requirement	Evidence
quality_mass	cp_mass	Implement mass_record_origin and mass_configuration with real calibrated complete-aircraft readings and measured corrections. Missing actual weighing method, equipment list or unreconciled cabin/fluid/propulsion state blocks quantitative completion.	original serial weighing/calibration/equipment/fluid reconciliation
quality_bom	all processes	Reconcile equipped sections/wings/tails, gear, systems, turbine engine versus nacelle/pylon/APU inclusions, complete customer cabin and retained fluids. Actual omitted resources/components are added atomically before any completed dataset claim; supplier and FAL manufacture are not double counted.	current drawing/BOM/serial supplier completion and test records
quality_route	turbofan; apu; jet_fuel; co2_air; no_air; no2_air; xylene_air	Verify aviation turbofan route and completed supply state, distinguish APU and outside ground engines. Retain actual Jet A-1 fuel grade/fossil share and measured air species/subcompartment; altitude-specific flight emissions need matching identities. Total VOC/NOx or piston/wind-turbine identity cannot substitute.	direct public flow fields, actual supplier SDS and measured test records
quality_evidence	dataset	Disclose actual site/period/gate, source lineage and coverage, conditional absence, uncertainty, allocation, all identity/quantity/upstream gaps and empirical QA basis. Derive ranges from actual calibrated records or independently verified compatible evidence, never invent mass, yield, life or emission thresholds. This methodology contains no factory observations or scientific approval.	original evidence and gap register

9. Validation Rules

rule_id	Applies to	Rule	source_ids
validate_reference	finished_machine; cp_mass	Verify single-aisle twin-turbofan complete civil passenger configuration, original unladen category above2000kg, positive actual empty net M and fixed1kg output. Reject partial prototype cabin, catalogue/MTOW/payload mass and unsupported density corrections.	faa-weight
validate_rows	all inventory rows	Every exchange has one actual chemical/physical identity, direction/type, compatible public reference property/unit, shared M and linked legal lowercase protocol/rule. Confirm Chinese official names, source, route and medium. Unresolved exact identities remain declared review gaps; an automated pass cannot establish their suitability.
validate_scope_balance	all processes	Reconcile net stocks, complete supplier inclusions, installed dry material and retained fluids, waste and actual ground/flight/test coverage. Unmeasured quantities, missing actual constituents/acceptance records or upstream datasets prevent an unqualified completed cradle-to-gate claim.	ghg-allocation

10. Published Dataset Profile
