IMSAFE Checklist
Illness Medication Stress Alcohol Fatigue Eating Emotion
Hazardous attitudes and their antidotes
Anti- authority ( don’t tell me what to do) antidote: follow the rules. They exist for a reason
Impulsivity ( Do something! Quickly!) antidote: Not so fast… Think First
Invulnerability ( It won’t happen to me) antidote: It could happen to me.
Macho: (It’s fine. I can do it) antidote: is this unnecessary risk?
Resignation (what’s the point?) antidote: I am not helpless!
What is risk management?
A way to effectively mitigate risk
Pave checklist
The pave checklist is a great way to evaluate your personal minimums and hazards you could could experience when flying.
P-pilot
A- aircraft
V- enVironment
E- external pressures
What is the 5 p’s checklist?
The 5 p’s are used to evaluate the pilots current situation at key decision points during the flight or when an emergency arises. These decision points include preflight, pretakeoff, hourly or at the midpoint of the flight, pre-descent, and just prior to final approach (or for vfr, just prior to entering the pattern)
The PLAN, The PLANE, The PILOT, The PASSENGERS, The PROGRAMMING
Why do people get motion sickness
The bran receives conflicting messages about the state of the body.
BAC limits
0.04% and no alcohol within 8 hours of flying.
What are the four types of hypoxia?
Hypoxic hypoxia
Hypemic hypoxia
Stagnant hypoxia
Histotoxic hypoxia
What is hypoxic hypoxia?
Most common form of hypoxia in aviation. Often called altitude hypoxia. Pilots experience hypoxic hypoxia when climbing in altitude in an unpressurized aircraft. As altitude increases. Air becomes less dense meaning oxygen molecules move farther and farther apart ( you get less O2 per breath) eventually, the lungs can cannot effectively transfer enough oxygen to the blood to be carried throughout the body.
What is hypemic hypoxia?
This hypoxia is caused by the the reduced ability of the blood to carry oxygen. Even though there may be an adequate supply of oxygen in the ambient air, the bloods anbility to transfer that oxygen has been impaired. The most common cause of hypemic hypoxia in aviation is CARBON MONOXIDE being inhaled from the aircraft heater.
The hemoglobin that transfer oxygen in our bodies bonds with carbon monoxide 200 times more readily than it bonds with oxygen.
What is stagnant hypoxia?
This hypoxia occurs at the circulatory level, if the blood flow is compromised for any reason, then sufficient oxygen cannot get to the body tissues. Decreased blood flow can be caused by the heart failing to pump effectively, arterial Constriction, cold temps ( because the blood flow is decreased to the extremities) or any condition that reduces or prevents the blood flow in any area of the body
What is histotoxia hypoxia
This type of hypoxia occurs at the cell level. This means the cell expecting and needing the oxygen is impaired and cannot use the oxygen to support metabolism. This is most frequently caused by alcohol, narcotics ands cyanide. Cyanide is one of the byproducts during the combustion of plastics.
What are the signs and symptoms of hypoxia?
Bluish discoloration of skin, lips, and oral cavity. Decreased levels of consciousness Fast heart rate Difficulty breathing Confusion Cough Sweating
