Study Notes
Megaphone
- Used for passenger instructions during PA system failure or evacuation
- Pre-flight check: present / in place, check if operative
- Operation: depress press-to-talk, speak into microphone, direct speaker
Halon Fire Extinguisher
- Pre-flight check: check pressure gauge in green band, locking pin through handle and lever
- Operation (TPASS): twist seal, pull pin, aim at base of fire, squeeze lever, sweep side to side
- Discharge range: approximately 20 feet
- Duration: 30-40 seconds
Water Fire Extinguisher
- Used for fires on ordinary combustibles (fabric, paper, plastic) where cooling is important
- Also used to dampen deep-seated fires after Halon use
- Discharge range: approximately 20 feet
- Duration: 30-40 seconds
ELT (Emergency Locator Transmitter)
- Duration: 48 hours
- Evacuation commands: brace for impact, bend over, stay down; evacuate, open seatbelts; water landing, come this way, step in, inflate life vest; terrain landing, come this way, jump; exit not usable, no exit, go that way
- Classification of turbulence: light, moderate, severe
- Asbestos hand gloves: for grasping hot or burning parts
- Two types of decompression: slow, rapid
Slow/Rapid Decompression
- Slow: gradual cabin pressure loss due to slow leak
- Rapid: loud bang or fog in cabin
Protective Breathing Equipment (PBE)
- Used to protect and aid cabin crew in fighting fires
- Do not use for electrical fires
Water Fire Extinguisher
- Do not use on electrical fires
Crash Axe
- Used to pry away panels if fire source difficult to locate
Unplanned Landing/Evacuation
- Unprepared emergency, no time to coordinate actions among flight crew
Turbulence
- Shaking or vibrating of aircraft
Lavatory Smoke Detector
- Sounds alarm if smoke in lavatory
Portable Oxygen Bottle
- High-pressure cylinders for supplementary oxygen to air crew and passengers
- Dual outlet: one outlet (HI) at 4 liters/minute, one (LO) at 2 liters/minute
- Sling strap, ON/OFF regulator valve, pressure gauge indicating contents, two constant-flow outlets (HI & LO).
Portable Oxygen Bottle Pre-flight Check
- Pointer in red band (full) of pressure gauge
Portable Oxygen Bottle Operation
- Ensure mask inserted into appropriate outlet; turn ON/OFF regulator valve counterclockwise; check flow indicator on tubing; fit mask over face; after use turn ON/OFF regulator valve clockwise to OFF position.
Examples Of No Doubt Get Out Situation
- Severe structural damage, water too deep, fire too hot, smoke too thick
