Myasthenia Gravis and Its Aeromedical Implications

Area of Science:

• Aerospace Medicine
• Neurology
• Immunology

Background:

• Myasthenia gravis is an autoimmune disorder affecting neuromuscular junctions.
• Symptoms include muscle fatigability and weakness, impacting aviation roles.
• This study examines UK Civil Aviation Authority data on myasthenia gravis.

Purpose of the Study:

• To review the aeromedical implications of myasthenia gravis.
• To analyze the impact on pilots and air traffic controllers.
• To propose a medical certification policy.

Main Methods:

• Retrospective review of UK Civil Aviation Authority medical records (1990-2016).
• Identified 11 individuals diagnosed with myasthenia gravis.
• Extracted data on certification, diagnosis, symptoms, treatment, and loss of certification.

Main Results:

• Included 2 Class 1, 6 Class 2 certificate holders, and 3 air traffic controllers.
• Mean age at diagnosis was 53 years (range 28-67).
• Mean interval to loss of certification was 22 months (range 0-108).

Conclusions:

• Myasthenia gravis has significant aeromedical implications.
• Consideration of complications, treatments, and functional impact is crucial.
• A proposed policy for medical certification is presented.
