Certification Flight Testing of the Bell 412EPI Increased Gross Weight Helicopter
Bibliographic record
Abstract
This paper presents a summary of the certification flight test program of the new Bell 412EPI Increased Gross Weight helicopter. Flight testing is described which supports an increase in the maximum gross weight of the Bell 412EPI from 11,900 lb to 12,200 lb. Measured data for a variety of flight conditions are presented, including CAT A rejected and continued takeoffs, height-velocity landings, simulated engine failures at high speed, static and dynamic stability, and ground resonance. Hover performance, low-speed controllability, and external loads testing are also discussed. A new CAT A backup procedure is developed that is applicable to both ground level and elevated heliports. This new procedure results in increased performance and reduced helipad size requirements. CAT A capability increased by 650 lb gross weight at 2,000 ft altitude, and increased altitude capability by 5,000 ft at 9,150 lb gross weight.

How this classification was reachedexpand
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 itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
