AIM (Aeronautical Information Manual) Flashcards
HYPOXIC HYPOXIA
Hypoxic hypoxia is the most common and is caused by decreased oxygen in air or the inability to diffuse the oxygen across the lungs.
If this happens, the person has less than 100% saturation of the blood in the arteries. This can happen if you are at an altitude where the oxygen content of air is low (i.e., over 12,500 feet). Another problem would be if a person’s lungs were damaged so oxygen transfer was impaired
HYPEMIC HYPOXIA
Hypemic hypoxia is caused by the reduction of the oxygen carrying capacity of the blood. Anemia (low hemoglobin) can cause this. The oxygen is available, but there isn’t enough good blood to carry the oxygen. Carbon monoxide poisoning will cause this type of HYPOXIA! The blood holds on to the carbon monoxide from the exhaust leak in your engine and your capacity to carry oxygen decreases, you become hypoxic!
STAGNANT HYPOXIA
Stagnant hypoxia is caused by reduced cardiac output (the pump isn’t working good enough) or by venous pooling during high G force stresses. We are all getting older and we have to remember that the function of the heart is essential for pumping the oxygenated blood.
HISTOTOXIC HYPOXIA
Histotoxic hypoxia occurs when all systems are working but the cells can’t take” the oxygen from the blood. The oxygen is available. Alcohol or cyanide poisoning can cause this.”

PROHIBITED AREA
(Define)
Established for security or other reasons associated with the national welfare.
May not use.
RESTRICTED AREA
(Define)
The flight of aircraft, while not wholly prohibited is subject to restriction. RA denote the existence of unusual, often invisible, hazards to aircraft such as artillery firing, airial gunnery, or guided missiles.May be used with permission from controlling agency.
WARNING AREA
(Define)
From 3 NM outward from the coast of the U.S. that contains activity that may be hazardous to nonparticipating aircraft.
May be located over domestic or international waters or both.
MILITARY OPERATIONS AREA (MOA)
(Define)
Established for the purpose of separating certain military training activities from IFR traffic. Whenever a MOA is being used, nonparticipating IFR traffic may be cleared through a MOA if IFR separation can be provided by ATC.Operations include; air combat tactics, air intercepts, aerobatics, formation training, and low altitude tactics. Active MOA may contain military aircraft in excess of 250 knots (below 10K feet). May enter, but pilots should contact FSS within 100 NM to determine if MOA is active. Prior to entering MOA pilots should contact controlling agency for traffic advisories.
ALERT AREAS
(Define)
Areas that may contain a high volume of pilot training or unusual type of aerial activity.
Pilots should be particularly alert when flying in these areas.
