Emergencies and Safety Flashcards
Engine driven vacuum is failed, what is affected?
Altitude and Heading
Electrical Failure
Digital system, turn coordinator, transponder, radio
When there is an instrument failure, do you need to notify ATC?
Yes,
try to get vectors to VFR
Avoid altitude changes and delay course changes
Oxygen requirements (§91.211)
Cabin pressure altitudes 12,500-14,000ft - crew must use supplemental O2 for periods of flight over 30 minutes at these altitudes.
Cabin pressure altitudes above 14,000ft – crew must be provided with and use supplemental O2 the entire flight time at these altitudes.
Cabin pressure altitudes above 15,000ft – each occupant must be provided with supplemental O2.
What is Hypoxic hypoxia?
insufficient supply of O2 to the body as a whole. As altitude increases, reduced pressure becomes insufficient for the O2 molecules to pass through the respiratory system’s membranes.
What is Hypemic hypoxia
Inability of the blood to carry the O2 molecules. It may be a result of insufficient blood (bleeding or blood donation), anemia, or CO poisoning.
What is Histotoxic hypoxia?
Inability of the body cells to affectively use the O2 supplied by the blood. This can be caused by use of alcohol or drugs.
What is Stagnant hypoxia?
Caused by the blood not flowing to a body tissue. Can be caused by heart problems, excessive acceleration (Gs), shock or a constricted blood
vessel.
What is Hyperventilation?
excessive amount CO2 of is eliminated from the body as a result breathing too rapidly. Symptoms may be similar to those of hypoxia.
cause of hyperventilation
panicked response to fear, stress, or a phobia.
action when hyperventilation happens?
Breathing into a paper bag or talking aloud helps recovery from hyperventilation.
What is Decompression sickness?
after scuba diving, where the body is subject to higher pressures.
Wait at least 12 hours after scuba diving if your flight is up to 8000ft cabin altitude, or 24 hours for higher cabin altitudes.
