Research on civil aircraft airworthiness verification technology for operating capacity on narrow runways
Bibliographic record
Abstract
Abstract Although airworthiness regulations implicitly consider runway width in requirements such as the determination of minimum control speed on the ground, there is no provision that explicitly requires the establishment of a minimum runway width for a specific type of aircraft. Although relevant materials such as ICAO (International Civil Aviation Organization) have given guidance on minimum runway widths applicable to aircraft operations, only TCCA (Transport Canada) has developed an AC (advisory circular) for narrow runway operations. Based on the reference to TCCA AC 525-014, this paper introduces the method of defining the minimum runway width of an aircraft applicable to narrow runway airworthiness verification, gives the additional airworthiness requirements for narrow-runway operations and the considerations for sorting out the affected basic airworthiness regulation requirements, and provides the compliance verification method and some examples. The research results of this airworthiness verification technology are universal and can provide important reference significance for the supplementary verification of narrow-runway operating capacity for civil aircraft.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
