2. Fire protection Flashcards
Hvað eru margar dual-loop detector á hvorri vél og hvað þarf margar til að það komi alarm?
Provided by two independent dual- loop detector systems on each engine. Normally, it is necessary for both loops to provide a warning signal before a fire or overheat alarm is made.
Hvenær er APU fire protection automatic?
When on ground with both engines shut down
Hvernig er cargo fire protection?
No extinguisher for the cargo areas. A push-button switch depressurizes all the cargo compartments

arms, both
Hver er munurinn á ljósunum; ENG BTL 1/2 DISCH og ENG BTL 1/2
ENG BTL 1/2 DISCH: Discharged
ENG BTL 1/2: Extinguisher bottle has low pressure
Geturðu slökkt á engine overheat viðvörunum?
Nei. The overheat lights remain illuminated as long as the overheat condition exists.
Hvernig er APU fire detection?
2 fire detector loops. No APU overheat detection. APU fire signal initiates automatic APU shutdown. One APU fire extinguisher bottle
Máttu fljúga með APU fire extinguishing inoperative?
Já, þetta er í MEL
Hvernig er main gear wheel well fire protection?
Bara fire detection og warning. Single fire loop.
Muntu fá warning ef það eru “hot brakes”?
Nei, bara ef það er eldur.
Ef þú færð nose gear wheel well fire, hvaða alarm færðu?
Ekki neitt held ég. The nose gear wheel well does not have a fire detection system.
Hvað gerir þú ef þú færð wheel well fire?
Landing gear lever down (maximum 270kts/0.82 M). Bíður svo í 20 mín eftir að eldur er slokknaður og þá seturðu gear aftur upp.
Hvað er forward og aft cargo compartments með marga smoke detectors?
Two
Each cargo compartment has ___ fans that can draw air through the smoke detectors. One fan operates at a time. The second or
standby fan starts automatically on….
two.
sensing a failure of the operating fan.
___ fire Extinguisher bottles are installed for cargo compartment fire extinguishing.
Two
Cargo compartment fire extinguishing; Hvað gerist aukalega ef þú armar forward system (vinstri takkinn)
Turns off both the left and right air conditioning recirculation fans. AFT slekkur bara á hægri viftu.
Each lavatory has a fire extinguisher (automatic discharge). Hvernig veistu að þetta hefur farið í gang?
Veist það á þeim vélum sem eru með cockpit annunciations en ekki öðrum.
Hvernig eru MEL reglurnar varðandi smoke detector system á lavatory?
4 installed en þarft 0. Læsir bara þeim salernum.
Hvernig er testing ferlið á fire og overheat detectors?
Automatic when electrical power is initially applied. Getur líka gert manual tests.
Í cargo vélunum, hvað gerist ef þú færð smoke signal?
Færð fire warning. Held þetta sé ekki þannig í venjulegu vélunum.
Hvernig í hnotskurn er overheat detection kerfið á vélunum?
Provided by two independent dual- loop detector systems on each engine.
Hvort er dual loop notað í fire- eða overheat detection?
Bæði
Er gas filled hollow conductor notað í fire- eða smoke detection?
Held bara fire protection
APU; Hvaða týpa er fire detection? Er overheat detection? Hvað gerist ef það er APU fire? Er APU fire bottles?
APU fire detection: 2 fire detector loops
Overheat detection: NEI
Hvað gerist: Automatic extinguishing
APU fire bottles: 1
Geturðu resettað engine fire and overheat detection?
Já, can be reset to allow monitoring of the remaining systems.
Hvenær skýtur þú second bottle í vélina í engine fire?
Þegar tjékklisti segir þér, ekki lengur memory item.
When an engine fire switch is pulled out, the associated engine: fuel is shut off, ____ valves are closed, _____ is tripped off, hydraulic fluid is shut off to the engine-driven hydraulic pump, fire extinguishing bottles are ____.
bleed, generator, armed
Hvernig er APU fire detection systemið í hnotskurn?

Does the APU FIRE have memory items?
No
Getur þú verið MELaður þannig að það vanti 1 loop í APU fire extinguishing og þú megir samt fara í loftið?
Já, það má vanta aðra fire detection loopuna (þær eru tvær í APU).
Hvað eru margar fire detector loops í vélum? En APU?
2 loops í hverri vél og 2 loops í APU.
