Basic Med Overview
Basic Med: An alternative to traditional medical certification,
Requires a valid driver’s license.
Must complete a medical checkup every 48 months and an online course every 24 months.
Can carry 7 passengers including oneself.
Cannot operate aircraft over 12,500 lbs, above 18,000 ft, or exceed 250 knots.
May not have had prior medicals revoked or suspended.
Responsibilities for Medical Conditions
Must report any disqualifying medical conditions after receiving medical certification, including issues such as:
Severe anemic conditions or high fever.
Ongoing responsibilities to report any new or worsening conditions impacting flying ability.
Proficiency vs. Currency
Currency: Refers to whether a pilot has flown more recently enough to legally act as pilot of an aircraft.
Proficiency: Refers to skill level and comfort performing particular flight maneuvers.
Example of Currency vs. Proficiency:
Past takeoffs and landings are recent but pilot may not feel comfortable after a long break or unfamiliar aircraft or systems (i.e., different avionics).
Human Factors in Aviation
Focus on how physical conditions affect pilots and their operational capabilities.
Types of Human Factors Concerns
1. Hypoxia
Definition: Inadequate oxygen supply to the body.
Types of Hypoxia:
Hypoxic: Caused by high altitude.
Hypemic: Typically results from carbon monoxide poisoning.
Stagnant: Caused by extreme G-forces preventing blood circulation.
Histotoxic: Impacts of substances (alcohol/drugs) preventing the body from utilizing oxygen effectively.
Solutions include:
Descent to lower altitudes,
Use of supplemental oxygen,
Emergency landing declaration when necessary.
2. Hyperventilation
Definition: Excessive breathing leading to decreased carbon dioxide levels.
Symptoms and Corrections:
Breathe slowly and deeply; accomplish this through controlled breathing methods, such as using a paper bag.
3. Middle Ear and Sinus Problems
Caused by pressure changes during flight, leading to sharp pain.
Solutions include using techniques to equalize ear pressure and avoiding flying when congested.
4. Spatial Disorientation
Disruption of awareness of the aircraft's orientation, more likely in limited visibility.
Recommended corrections involve trusting instrument readings over sensory perceptions.
5. Motion Sickness
Results from conflicting signals to the brain regarding motion; suggested corrections include stabilizing focus on distant, immobile points, and ensuring adequate ventilation.
6. Carbon Monoxide Poisoning
Inhaled gas from exhaust that binds with hemoglobin preventing oxygen transport; symptoms include headaches and dizziness.
Key Prevention Steps:
Turn off cabin heat and ventilate cabin, use carbon monoxide detectors.
7. Stress and Fatigue
Types: Acute and Chronic
Acute: Short-term, immediate stressors; Chronic: Long-term, persistent stressors.
Recommendations: Perform self-assessment on current stress/fatigue levels before flying.

Basic Med Overview
Basic Med: An alternative to traditional medical certification.
Requires a valid driver’s license and must have held a medical certificate at some point after July 14, 2006.
Must complete a medical checkup every 48 months and an online course every 24 months.
Can carry up to 6 occupants (5 passengers plus the pilot).
Cannot operate aircraft over 6,000lbs maximum takeoff weight (MTOW), above 18,000ft MSL, or exceed 250knots.
Proficiency vs. Currency
Currency: Refers to whether a pilot has met the legal minimum requirements (e.g., 3 takeoffs and landings within 90 days) to act as pilot in command.
Proficiency: Refers to the pilot's actual skill level and ability to fly safely and competently in various conditions.
Human Factors in Aviation
Focus on how physical conditions affect pilots and their operational capabilities.
1. Hypoxia
Definition: Inadequate oxygen supply to the body's cells and tissues.
Causes and Types:
Hypoxic: Lack of available oxygen in the air (high altitude).
Hypemic: Blood cannot carry oxygen (carbon monoxide poisoning or anemia).
Stagnant: Blood is not moving (high G-forces or cold temperatures).
Histotoxic: Cells cannot use the oxygen provided (alcohol or drug use).
Symptoms: Euphoria (false sense of safety), cyanosis (blue tint to fingernails and lips), headache, drowsiness, impaired judgment, and increased reaction time.
Solutions: Descent to lower altitudes, use of supplemental oxygen (FAR 91.211 requirements), or emergency landing.
2. Hyperventilation
Definition: Breathing at an abnormally rapid rate, resulting in excessive loss of carbon dioxide (CO_2).
Causes: Stress, anxiety, or fear often trigger an increased breathing rate.
Symptoms: Dizziness, tingling in the extremities (hands and feet), muscle spasms, and lightheadedness.
Corrections: Consciously slow the breathing rate; talk out loud, or breathe into a paper bag to re-inhale CO_2.
3. Middle Ear and Sinus Problems
Anatomy: Involves the Eustachian tubes, which connect the middle ear to the throat to equalize pressure.
Causes: During climb or descent, gas in the ears and sinuses expands or contracts. If the Eustachian tube is blocked by congestion or inflammation, the pressure cannot equalize.
Symptoms: Severe, sharp pain in the ears or forehead/face; possible temporary hearing loss or eardrum rupture.
Solutions: Level off and descend slowly; use the Valsalva maneuver (pinch nose and blow gently) to equalize pressure; avoid flying with a cold or sinus infection.
4. Spatial Disorientation
Definition: A state of temporary confusion resulting from misleading sensory information relative to the aircraft's position.
The Three Systems:
Vestibular System: Inner ear organs (semicircular canals and otolith organs) that sense balance and acceleration.
Visual System: Eyes which provide the primary source of orientation.
Somatosensory System: Nerves in joints and muscles ('seat of the pants' feeling).
Causes: When visual cues are lost (clouds/darkness), the vestibular system can provide false sensations (e.g., 'the leans' or Coriolis illusion).
Corrections: Trust the flight instruments and ignore bodily sensations.
5. Motion Sickness
Causes: Conflicting signals between the vestibular system (sensing motion) and the visual system (eyes sensing a fixed cabin interior).
Symptoms: Nausea, dizziness, paleness, cold sweating, and vomiting.
Corrections: Look at a point outside on the horizon, increase fresh air flow, and avoid unnecessary head movements.
6. Carbon Monoxide Poisoning
Cause: Inhaled exhaust gases (containing CO) entering the cabin, usually via a leaky heater shroud. CO binds to hemoglobin 200 times more effectively than oxygen.
Symptoms: Headache, blurred vision, dizziness, and eventual loss of consciousness.
Key Prevention Steps: Shut off cabin heat, open all vents/windows, and land as soon as possible.
7. Stress and Fatigue
Acute Stress: Short-term response to immediate threats.
Chronic Stress: Long-term psychological pressure that drains energy.
Fatigue: Can be acute (lost sleep) or chronic (long-term exhaustion). It results in slowed reaction times and poor decision-making.
