Gossamer Condor

Condor identification

Recognition requires an explicit link to the Condor design rather than a generic human-powered-aircraft description.

1. Which document or identifying feature establishes that this subject is the Gossamer Condor? definition
2. Does the record describe the Condor, the Albatross, a replica or a depiction? boundary

Configuration consistency

Dimensions, photographs and flight results should be combined only when their configuration relationship is established.

1. Which dated drawing, photograph or test log identifies the hardware described? provenance
2. Which components changed between this configuration and the prize-flight configuration? boundary

Power budget evidence

Pilot output, transmission losses and propeller demand require separate evidence rather than a single unexplained power figure.

1. How did the documented pedal and transmission arrangement drive the propeller in this configuration? definition
2. What pilot power and duration were measured or estimated, and at which point in the drive system? measurement

Configuration-specific performance

Wing geometry, loaded mass and flight speed must share a stated configuration and observation basis.

1. What were the wing span, wing area and aircraft-plus-pilot mass for the flight being assessed? measurement
2. Is the reported speed airspeed or groundspeed, and what wind and flight height accompanied it? measurement

Documented control mechanisms

Record actual surfaces, flexible geometry and linkages before assigning conventional pitch, roll or yaw labels.

1. Which surfaces or structural deformations did each pilot control actuate in the prize-flight configuration? definition
2. Which tests establish the resulting turn response and any coupling between pitch, roll and yaw? provenance

Prize-flight evidence

The Smithsonian records Bryan Allen completing the required figure-eight flight on August 23, 1977. [Smithsonian exhibition record](https://www.si.edu/exhibitions/gossamer-condor%3Aevent-exhib-5075)

1. Which contemporary rules and adjudication records establish the required course, clearance and completion conditions? provenance
2. Which observed results support course completion, and which broader performance claims remain untested? boundary

Material and load-path map

AeroVironment describes aluminum tubes, Mylar covering and wire bracing; component-specific construction still requires drawings or inspection. [AeroVironment history](https://www.avinc.com/images/uploads/news/Gossamer_Condor_Use_Case.pdf)

1. Which members, joints and bracing wires carry loads in the documented configuration? definition
2. What evidence records film damage, tube deformation or bracing changes and their effects on geometry? measurement

Iteration history

AeroVironment identifies rapid modification and repair as central to Condor development. [AeroVironment history](https://www.avinc.com/images/uploads/news/Gossamer_Condor_Use_Case.pdf)

1. Which repair or modification followed each recorded damage event or control problem? provenance
2. What evidence would be needed to show that a repaired configuration retained its intended mass, alignment and control response? action

Historical-to-museum provenance

AeroVironment reports donation to the Smithsonian in January 1978; the surviving component history requires collection documentation. [AeroVironment history](https://www.avinc.com/images/uploads/news/Gossamer_Condor_Use_Case.pdf)

1. Which accession and conservation records connect the preserved aircraft to the prize-flight hardware? provenance
2. Which components are original, development replacements, conservation replacements or display supports? boundary

Intervention basis

Present handling, conservation or testing decisions require current condition evidence and custodian authorization.

1. What dated inspection documents the condition of the covering, joints, bracing and support points? measurement
2. Which handling or conservation actions has the custodian authorized, and what further assessment is required before any mechanical test? action
