Abstract
This paper presents the results of a new method used for constructing an aircraft’s vertical navigation profile (VNAV) envelope, applied on an aircraft performance model described by linear interpolation tables. The method was developed for use in Flight Management System (FMS) trajectory computations and optimization. The main objective was to speed-up the trajectory generation/update and to reduce the volume of repetitive computations, especially those associated with a trajectory optimization. It considers a free-flight scenario with a vertical profile composed of unrestricted climb, constant-speed level flight, climb-in-cruise (no descentin-cruise) and continuous descent segments, at specified climb, cruise and descent speed schedules and a specified value of the air temperature deviation. It uses the same set of aircraft performance data (PDBs) as the FMS platforms.

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
