Abstract
This paper provides industry perspectives regarding design and structural certification issues linked to application of composite materials on modern aircraft structures. Today, composite materials still offer the promised high specific strength and stiffness properties that attracted the industry to these materials decades ago, but when applied to aircraft applications, significant potential weight savings have seemingly been unrealized in modern certified aircraft. Aircraft undergo a rigorous certification process that is intended to ensure flight safety and reliability of the vehicle throughout production and service. Compliance with structural design criteria imposed by the certification process has resulted in unsurpassed airframe structural integrity and aircraft operational safety. However, in light of this industry-wide success one might question if further improvements in weight and performance are achievable (or being ‘left on the table’ so to speak). Thus, the body of this paper provides insight into (a) aspects of airframe certification-related issues that present hurdles for implementation of new composite weightand cost-saving technologies, and (b) practical areas for focused beyond-the-state-of-the-art composites research.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model 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 it
