Study Notes
Audiometry for Class 2 Medical Certificates
- Class 1 and Class 2 medical certificates require hearing tests using pure-tone audiometry for initial examination and subsequent evaluations at specified intervals based on age.
- For initial applicants, the maximum permissible hearing loss is 35 dB at 500, 1000, and 2000 Hz, and 50 dB at 3000 Hz, individually for each ear. Greater hearing loss necessitates demonstrating satisfactory functional hearing ability.
Hearing Evaluation Requirements
- Cabin crew members and class 2 pilots must accurately understand conversational speech at a distance of 2 meters with their backs turned to the examiner.
Mental Health Self-Rating Questionnaires
- Self-rating questionnaires like PHQ are beneficial for mental health assessments.
- Responses depend on the individual's openness and insight, making results subjective.
- Questionnaires are time-bound and do not provide definitive diagnoses.
Regulatory Frameworks
- European Union Aviation Safety Agency (EASA) guidelines replaced previous Joint Aviation Authorities (JAA) standards.
- Other regulatory frameworks include the International Civil Aviation Organization (ICAO) and the Federal Aviation Administration (FAA).
Definition and Limitations of LAPL
- LAPL (Light Aircraft Pilot License) permits operation of single-engine piston airplanes up to 2000 kg takeoff mass, with a maximum of three passengers, strictly for non-commercial purposes and VFR (Visual Flight Rules).
Seeking Aeromedical Advice
- Certificate holders must consult aeromedical professionals under specific conditions, including surgery, medication use, significant injury or illness, pregnancy, hospitalization, or needing corrective lenses.
Pneumothorax Assessment
- Applicants with spontaneous pneumothorax are generally unfit until assessing respiratory stability six weeks post-recovery, including full re-expansion and absence of bullae.
Communication in Aviation
- Non-verbal communication is crucial; body language constitutes approximately 55% of communication.
- Calculation of maximum waiting time for pilots concerning medication adheres to a five-fold pharmacologic half-time.
Decompression Sickness
- Signs include bends, chokes, CNS disorders, and creeps. Risk factors include scuba diving before flight, alcohol consumption, atrial septal defects, body fat, age (higher incidence in older adults), gender (women are at greater risk), exercise levels, critical altitudes, and exposure duration.
Eye Examination Protocols
- Failing the Ishihara test necessitates further testing (e.g., Lantern Test or CAD Test) to determine color vision safety.
- Limitations pertaining to visual capabilities can only be lifted by the Aviation Medical Examiner (AME) in coordination with aviation authorities.
Head Injury Reporting
- Individuals with significant head injuries must be evaluated by a neurology specialist, ensuring full recovery and minimal risk of epilepsy.
Effects of Microgravity on Human Body
- Microgravity exposure results in fluid shifts, space adaptation syndrome, muscle atrophy, bone loss, renal stones, ionizing radiation exposure, and may lead to neuro-ocular syndromes or back pain.
Colour Vision Testing
- Colour vision is assessed through specific tests, including the Ishihara test, with further evaluations possible should candidates not meet the required standards.
