Engine Fire Protection Flashcards
What is the primary extinguishing agent for class B and C fires?
CO2
The core resistance material, which prevents current flow at normal temperatures, is the ________ continuous-loop fire detector system.
Kidde & Fenwal
Where do you discharge the fire-extinguishing agent?
Area between engine and cowling
The sensing element consists of a small (0.089 in OD) lightweight, Inconel tube with a pure nickel wire center conductor. With a length of 1.5 to 15 feet, is the ________ continuous fire detection system.
Fenwal
When you pull the fire handle it accomplishes which sequence of events?
closes fuel firewall Shutoff valve, Hydraulic firewall shutoff valve, pneumatic shutoff valve, Electrically disconnects generators, Arms discharge cartridges
All fire extinguishing systems for aircraft are required to incorporate indicators by which the system condition is shown. True or False?
True
Utilizing two separate agent containers for each area or by incorporating a cross feed system so that extinguishing agent can be drawn from either of two different containers for each engine is the _____ _____ feature.
Two shot
When a fire occurs, the temperature in the area of the active thermocouples will exceed the temperature of the reference thermocouple, causing a current to flow through sensitive relay. True or False?
True
When the Yellow indicator disk is missing it indicates what?
Normal discharge through firing of the squibs
Dry Powder is used for Class ______ Fires.
D
The system, when any portion of the sensor tube is exposed to fire, the gas absorption material immediately releases a large quantity of gas, which quickly increases the pressure in the tube to a level necessary to close the diaphragm switch is the _____________ system.
Systron-donner
A _______ disk and _______ disk retain the extinguishing agent in the (HRD) container.
Breakable & Fusible
The outer tube is constructed of stainless steel. Between the inner and outer tubes, an inert gas (helium) is contained under pressure. This is the __________ system.
Systron-donner
The Kidde system has two electric conductors. True or False
True
What electrically discharges the cartridge in the selected bottle allowing the extinguishing agent to escape into the plumbing?
The bottle discharge button
Single wire surrounded by a continuous string of ceramic beads within an inconel tube describes the ___________ system.
Fenwal
What is contained as a liquid, when released it becomes a gas, and smothers a fire by displacing the oxygen?
CO2
A feed-through electrical connector that passes though a firewall is a ________
connector.
Bulkhead
This type of fire detection system operates on the principle of a buildup of gas pressure within a tube proportional to temperature.
Systron-Donner
Each sensing loop is connected to its own electronic control circuit mounted on a separate circuit card to provide redundancy, thus ensuring operation of the system even if one side fails. This is the
_________ system
Kidde
