Abstract
This article describes the lucrative market for single-aisle narrow-body (SANB) commercial aircraft for the next 20 years. The SANB market has been the most lucrative for engine manufacturers. Boeing’s 737 and Airbus’s A320 families are powered by twin 30,000 pounds-thrust engines from CFM International or from International Aero Engines number in the many thousands. Of the 19,400 airplanes now in the worldwide air transport fleet, according to Airbus, for aircraft above 100 seats, 87% of all routes flown and 78% of all seats offered are in SANB airplanes. With the single-aisle jet liner market at record levels, not surprisingly, new players want a piece of this Boeing/Airbus duopoly pie. Both Airbus and Boeing have relied extensively over the last few years on customer financing support from export credit agencies such as the U.S. Export–Import Bank. The Russian and Chinese jets are government funded. Bombardier is getting Canadian and provincial government aid to develop the CSeries.

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
