CS2 LPA-D03-PROTECTED: Evaluation of a next generation oxygen system – assessment of usability, comfort and human performance
Bibliographic record
Abstract
The use of an oxygen system has many crucial aspects regarding usability, comfort, and its effects on human performance. To overcome shortcomings of common systems, a new oxygen mask was developed. It was aimed at enhancing the devices’ comfort and ease of use and at enabling the interoperability of the oxygen system within the cockpit environment. The project was a cooperation between the German Aerospace Center (DLR) and Safran Aerosystems (Clean Sky 2 Joint Undertaking framework). Our aim was to evaluate the new oxygen system with the parts oxygen mask and human-machine interface and to compare it to a customary system. Experiments using 20 pilots were conducted in two demonstrators providing the two oxygen systems. The procedure included normal cruise flight operation and emergency scenarios. Data were assessed by use of computerized questionnaires and cognitive performance tasks. Results showed that subjects were more satisfied with the usability and the comfort of the new mask at all three measurement time points. Cognitive performance with the new mask was not significantly impaired compared to the customary (legacy) mask. Differential effects and conclusions for the further development process are 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.
