Abstract
This article describes the newest regional aircraft model from Bombardier, which stretched its 86-seat CRJ900 to 100 seats, creating the CRJ1000, which launched in February 2007. Initial sales push is aimed at Europe, but the company hopes to penetrate the North American market if pilot scope clauses are relaxed. First flight is set for summer of 2008, with service entry in the fourth quarter of 2009. Brazilian rival Embraer is following a similar route, with two models that can be configured to seat more than 100. Analysts predict that aircraft in the 91- to 120-seat segment will account for 47 percent of deliveries over the next 20 years, as airlines hope to increase efficiency by replacing aging aircraft and expanding into mid-sized markets. Emerging markets, such as China, are also likely sources of customers. A Chinese manufacturer is developing a model that it says has been ordered in large numbers from many major Chinese carriers. A Russian manufacturer is also eyeing entry into the market, with a Russian Regional jet that began final assembly in March 2007.

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.
