What type of fire extinguishing agent would you use on an aircraft brake fire?
For small wheel and brake fires that have minimal exposure hazards, your first option should be a potassium-based, Purple-K dry chemical extinguisher.
What method is used to detect the thermal discharge of a built-in fire-extinguisher system?
Dry powder chemical. What method is used to detect the thermal discharge of a built-in fire-extinguisher system? A rupture of the red plastic disk in the thermal discharge line.
How is the thermocouple fire warning system activated?
A metal cage surrounds the thermocouple to give mechanical protection without hindering the free movement of air to the hot junction. If the temperature rises rapidly, the thermocouple produces a voltage because of the temperature difference between the reference junction and the hot junction.
What evidence will indicate that an installed fire extinguishing system has been intentionally discharged?
1105 Exam
| Question | Answer |
|---|---|
| In some fire extinguishing systems, evidence that the system has been intentionally discharged is indicated by the absence of a? | yellow disk on the side if the fuselage |
Which fire extinguishing agents used in hand operated extinguishers are acceptable for general use in aircraft?
Halon fire extinguishing agents that have been approved for use in aircraft include Halon 1211, Halon 1301, and a combination of the two (Halon 1211/1301) Both are typified as “clean agents,” leaving no agent residue after discharge.
What type of fire extinguisher is recommended for extinguishing a brake fire?
What type of fire extinguisher is recommended for extinguishing a brake fire? A dry-powder type extinguisher.
What retains the nitrogen charge and fire-extinguishing agent in a high rate of discharge HRD container?
What retains the nitrogen charge and fire-extinguishing agent in a high rate of discharge (HRD) container? Breakable disk and fusible disk.
What is the ATA code for fire protection?
Aircraft systems
| ATA Number | ATA Chapter name |
|---|---|
| ATA 23 | COMMUNICATIONS |
| ATA 24 | ELECTRICAL POWER |
| ATA 25 | EQUIPMENT /FURNISHINGS |
| ATA 26 | FIRE PROTECTION |
What is fire detection system in aircraft?
Fire protection systems are installed on aircraft to detect and protect against an outbreak of fire. These systems monitor the conditions which could lead to a fire and are comprised of smoke detectors, heat sensors near engines or hydraulic systems and visible and audible warnings in the cockpit.
What is thermocouple system?
A thermocouple is a sensor that measures temperature. It consists of two different types of metals, joined together at one end. When the junction of the two metals is heated or cooled, a voltage is created that can be correlated back to the temperature. Thermocouples are commonly used in a wide range of applications.
What is the primary extinguishing agent the fire service uses for extinguishing fires?
Foam is the primary agent used for extinguishing aircraft fires. Foam fire suppressant consist of a combination of bubbles of a lower specific gravity than that of hydrocarbon fuels or water.
What retains the nitrogen charge and fire-extinguishing agent in a high rate of discharge container?
Contact with the air converts the liquid into snow and gas which smothers the flame. What retains the nitrogen charge and fire-extinguishing agent in a high rate of discharge (HRD) container? Breakable disk and fusible disk.
