Where does hypoxia usually occur? What are some symptoms?
From 12,000 to 15,000 feet, judgement, memory, alertness, coordination, and ability ti make calculations are impaired. Also, headache, drowsiness, dizziness, and either a sense of well being or belligerence occur. Effects are worse above 15,000 feet
What is Hypoxia?
oxygen deficiency in the body sufficient to impair functions of the brain and other organs. Not enough oxygen getting to the blood.
What factors can make a pilot more susceptible to hypoxia?
Smoking, alcohol, drugs, and poor health
How can hypoxia be avoided?
Pilots are encouraged to use supplemental oxygen above 10K during the day and 5K at night
What is hyperventilation?
Breathing too much air in and out of the lungs. This reduces the carbon dioxide in the blood, which is needed to regulate the breathing process
What symptoms are associated with hyperventilation?
light headedness, suffocation, drowsiness, disorientation
What is carbon monoxide poisoning? How does it occur? What are the symptoms? What are the reactive actions?
1) Carbon monoxide poisoning is a colorless, odorless, and tasteless gas contained in exhaust fumes. It affects the body’s ability to carry blood
2) Airflow from the exhaust pipe is used to heat the cabin. If there is a crack, carbon monoxide can enter the cabin.
3) Headache, drowsiness, dizziness
4) Shut off the heater and open all air vents
What is the cause of motion sickness? What are the symptoms? What cations should be taken?
1) Caused by the continued stimulation of the inner ear which controls the sense of balance.
2) The symptoms are progressive. Loss of appetite, saliva collecting in the mouth, perspiration, nausea, and possible disorientation. Headaches and vomit may follow. The pilot/passenger could become incapacitated.
3) Open the air vents, loosen the clothing, use supplemental oxygen, and keep eyes on a point outside the airplane. Avoid unnecessary head movements.
What is Ear Block? How can you prevent ear block?
Ear block is when you cannot equalize the ear pressure in your middle ear to the aircraft’s cabin pressure. The difference holds the Eustachian tube closed, causing for severe pin and loss of hearing that can last several hours to several days.
It can be prevented by swallowing, yawning, tensing muscles in the throat. If this doesnot work, hold your nose and blow.. or just dont fly
What are the regulations concerning alcohol?
8 hours and .04 % BAC. Good rule of thumb is to allow at least 12-24 hours.
How do scuba diving affect flying?
For Flights up to 8000 FT MSL:
1) 12 hours after a dive not requiring a controlled descent
2) 24 hours after a dive requiring a controlled descent
For flights above 8000 FT MSL:
1) Wait at least 24 hours after any dive
