Case Studies in Modeling Cruise-Generated Trailing Vortices
Bibliographic record
Abstract
Trailing vortices from jet transport aircraft in high-altitude cruising flight have been measured in high spatiotemporal detail by a research jet operated by the National Research Council Canada. The vortex locations and circulations; descent rate; and vortex core thermodynamic, dynamic, transport, and spatial scale characteristics were derived. Also, from these measurements, the background atmospheric state properties of pressure, wind structure, temperature, thermal stratification, and turbulence have been established. Selected cases from the measured data have been used to evaluate two versions of the Probabilistic 2-Phase (P2P) wake vortex prediction model. While the default P2P version uses ground-based measurement data to calibrate its probabilistic envelopes, the runtime-optimized airborne version (P2P a ) uses uncertainties of all relevant impact parameters to construct the probabilistic envelopes. Flight and model data have been compared, and the suitability of the P2P model versions for onboard wake vortex prediction and warning during cruise have been discussed.

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.
