NASA is building the X-59 QueSST, an experimental aircraft for quiet supersonic flight over land. Supersonic flight is faster than the speed of sound and produces a sonic boom, an extreme form of noise pollution. QueSST stands for “Quiet SuperSonic Technology.” The X-59 QueSST is testing the technology to fly faster and more efficiently, and to reduce the loudness of a sonic boom reaching land.

This document provides the standards and administrative procedures for the aviation medical certification of NASA aviation flight personnel. It ensures that aviation medical certification practices will be implemented consistently across the Agency and provides details on the criteria for NASA aviation medical certification. These standards and processes define aviation medical certification requirements for aviation flight personnel and define an Agency aviation medical certification process, aviation medical standards, and medical evaluation requirements.
