Pre-Flight: A Benchmark for Evaluating Large Language Models on Aviation Operational Knowledge

arXiv:2607.01829v1 Announce Type: cross Abstract: Large language models (LLMs) are increasingly proposed for aviation business operations, from documentation and training generation to customer facing assistants. General purpose benchmarks do not measure whether a model reasons safely and correctly about aviation specific operational knowledge, and the high stakes, regulated nature of the domain makes that gap consequential. We present Pre-Flight, an open source benchmark of 300 multiple choice questions drawn from international standards and airport ground operations material, covering intern

Why this matters
Why now

As LLMs proliferate, there is an urgent need to develop domain-specific benchmarks in high-stakes environments like aviation to ensure safe and reliable deployment.

Why it’s important

This benchmark addresses a significant gap in evaluating LLMs for critical aviation operations, directly impacting safety, regulatory compliance, and public trust in AI applications within the industry.

What changes

The availability of a dedicated benchmark like Pre-Flight enables robust, standardized testing of LLMs tailored to aviation, fostering more secure and effective AI integration.

Winners
  • · Aviation operators
  • · AI developers focused on enterprise solutions
  • · Regulatory bodies
  • · AI safety researchers
Losers
  • · Developers of general-purpose LLMs without domain-specific training
  • · Manual documentation and training providers
Second-order effects
Direct

Pre-Flight will become a standard for validating LLMs in aviation, driving specialized AI development and deployment.

Second

Increased adoption of AI in aviation operations due to higher confidence in safety and performance, potentially leading to efficiencies and new services.

Third

The success in aviation could spur the creation of similar high-stakes, domain-specific benchmarks across other regulated industries, accelerating safe AI integration broadly.
