How frequently are Landing Signal Officer (LSO) physical required?

• A. Annually
• B. Monthly
• C. Quarterly
• D. Biennially

Answer: (D)

Landing Signal Officer duties require ongoing readiness to manage flight deck operations, signal aircraft accurately, and react quickly in a high-stakes environment. The physical exam for this role focuses on core areas that support safe performance: vision (including color perception for signal identification), hearing, cardiovascular health and endurance, neurological and musculoskeletal function, and overall fitness for duty. A two-year interval keeps these critical health aspects monitored regularly enough to catch issues that could affect safety, while avoiding the unnecessary disruption of a more frequent annual or monthly exam. This balance aligns with the typical aviation support medical requirements, ensuring the LSO remains capable without imposing excessive medical downtime.
