Purpose and description
Enable an AI agent to recognise the Sukhoi Su-27 aircraft type, distinguish its variants and derivatives, and assess what configuration, condition and authorisation evidence is needed before proposing an action involving an example.
The Sukhoi Su-27 is a Soviet-designed, twin-engine, highly manoeuvrable supersonic fighter aircraft type developed primarily for long-range air superiority, with single-seat and two-seat variants.
It can be Classify a candidate aircraft record as a documented Su-27 variant, a related type or unresolved.; Compare published Su-27 specifications after aligning variant, configuration, units and test conditions.; Identify the manuals and configuration records needed to evaluate a particular airframe.; Flag maintenance, modification or identity evidence that is missing or inconsistent.; Determine whether a proposed inspection, display, transfer or operation needs specialist assessment or additional authorisation..
Distinguishing features
Require a documented Su-27 designation and variant suffix; a Flanker reporting name or visual resemblance alone does not establish membership.
Use the combination of twin engines, twin vertical tails, blended wing-body form and separated engine nacelles as a visual consistency check, then resolve similar Sukhoi types through records.
Check seating and canopy arrangement against the claimed variant; a two-seat aircraft requires differentiation between Su-27 trainer variants and related two-seat types.
Check for carrier-related features, canards and other derivative-specific changes; their presence requires resolving the exact designation rather than automatically classifying the aircraft as a baseline Su-27.

Bundle to layer to finding to question, as the second pass will find it: 6 bundles · 11 layers · 18 findings · 28 questions.
Su-27 identity and family boundaries Establishes what the registered Su-27 entry includes and how candidate records demonstrate membership.
Su-27 terminology can refer loosely to a wider family whose members require distinct specifications and authority.
Designation evidence
Connects names and variant suffixes to traceable identification records.
Documented type membership
Record the evidence supporting a Su-27 designation without treating an informal family name as decisive.
- Which manufacturer, service or airframe identification record establishes the exact Su-27 designation? provenance
- Does the source describe the aircraft type, a production variant or one serial-numbered airframe? boundary
Variants and derivatives
Resolves trainer, export and modified configurations against neighbouring aircraft types.
Variant boundary
Represent documented relationships without assuming every Flanker derivative belongs inside this entry.
- Which Su-27 suffixes are included, and what evidence distinguishes them from separately designated Su-30, Su-33 or Su-35 aircraft? boundary
- If an airframe was converted or redesignated, which identity applies to the date being described? provenance
Airframe and installed systems Describes the configuration distinctions needed to interpret a Su-27's physical and functional characteristics.
A recognisable Su-27 silhouette does not establish the installed engines, controls or avionics.
Airframe and propulsion
Relates geometry, seating and engine installation to the documented variant.
Physical configuration
Keep dimensions, mass conventions and propulsion records attached to their actual configuration.
- What dimensions, seating arrangement and engine designation are documented for this Su-27 variant? measurement
- Which changes from its production configuration are supported by modification records? provenance
Controls and avionics
Distinguishes flight-control and mission-system installations across Su-27 configurations.
Installed system standard
Associate system descriptions with verified installations rather than a generic Su-27 capability list.
- Which flight-control, radar, navigation and communication standards are supported by the configuration evidence? provenance
- What documentation establishes compatibility between installed replacements, upgrades and the claimed variant? boundary
Performance and operating limits Makes Su-27 performance claims interpretable through configuration, conditions and documentary authority.
Range, speed and manoeuvring claims are misleading when detached from loading and the applicable flight documentation.
Performance basis
Captures the conditions behind quoted capacities and performance.
Conditional performance
Treat published performance as a conditioned claim rather than an unconditional property.
- For each quoted speed, range or altitude, what variant, loading, fuel state and flight profile does the source specify? measurement
- Is the value an approved limit, a test result, a manufacturer claim or an estimate? provenance
Approved limitations
Connects operating restrictions to the aircraft's current configuration.
Applicable flight documentation
Require the governing documentation before interpreting operational eligibility.
- Which flight-manual revision and supplements govern this Su-27 configuration? provenance
- Which documented restrictions arising from modifications, loading or system status affect the proposed activity? action
Maintenance and condition evidence Defines the evidence needed to interpret the condition of an individual Su-27 without embedding its logbook in the type model.
Age, service history, component limits and preservation can make superficially similar airframes eligible for very different uses.
Structural and component life
Connects recorded usage and inspections to applicable life limits.
Life-limit evidence
Identify required usage measures and supporting records for the airframe and life-limited components.
- Which approved limits apply to the airframe, installed engines and other life-limited components? provenance
- Are hours, cycles, calendar life and any authorised extensions traceable through the available records? measurement
System condition and preservation
Distinguishes documented serviceability from storage, display or incomplete restoration.

- What inspection or test records establish the status of engines, flight controls, hydraulic systems, landing gear and escape equipment? provenance
- Which preservation, consumable replacement or specialist inspections are required before the proposed use? action
Authority and safe use Connects a proposed activity involving a Su-27 to responsible authorities, qualified personnel and configuration-specific safeguards.
Military service, private operation and museum display require different evidence of permission and safe condition.
Governing authority
Identifies the regime and documents governing a particular example and activity.
Activity authorisation
Record the actual approval basis rather than assuming a universal Su-27 certification standard.
- Which military or civil authority governs this airframe, and which approval covers the proposed activity? provenance
- What qualifications, restrictions and validity conditions must be checked before that activity proceeds? action
Ground and display safety
Accounts for hazards that depend on installed equipment and preservation status.
Hazard status evidence
Treat escape-system, fuel, pressure and installed military-equipment status as matters requiring documented specialist assessment.
- What records establish whether escape-system pyrotechnics, residual fuel, stored pressure and installed military equipment remain hazardous? provenance
- Which documented access restrictions and specialist clearances apply before handling, transport or public display? action
Evidence and external alignment What the world already says about this thing, gathered so the model can be checked against it.
A model that cannot be lined up against existing standards, identifiers and practice cannot be adopted by anyone who already uses them.
