Abstract
The design and operation of long-range aircraft are driven by increasing passenger demand, higher fuel prices and environmental concerns. A possible solution to mitigate these concerns is to design long-range transport aircraft for shorter ranges and operate them using intermediate stops or stages. Staging could result in substantial fuel burn savings and decrease in direct operational cost. However, such benefits might be counterbalanced by longer trip duration and increased number of flight cycles. A tighter integration between the design of the aircraft and its operation assignment in long range operations can identify better configurations that overcome some of the penalties incurred in staging. This paper explores the benefits and impacts that a coupled optimization approach to aircraft design and staging allocation brings in terms of fuel efficiency, cost effectiveness, and emissions. Results show optimum configurations that take advantage of intermediate stops to reduce fuel and operating cost with moderate increases in flight time.

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
