FAA Advisory Circular Flashcards
What does HRET stand for?
High Reach Extendable Turret
What is the main benefit of using an HRET during ARFF operations?
Faster and more accurate firefighting with reduced agent usage
What configuration allows HRET to extinguish fire 53% faster than roof turrets?
Down-in-front attack mode
What is the ideal flow rate for precision application with HRET?
250 to 500 GPM
What advantage does the skin-penetrating nozzle provide?
Extinguishes fire inside aircraft, reduces interior temperatures, ventilates smoke
How often should ARFF operators be requalified?
At least annually
What training tool allows simulated ARFF driving and HRET operations?
Full-size cab mockups or desktop virtual joysticks
What type of camera is essential for piercing accuracy?
FLIR (Forward Looking Infrared) camera
What is the minimum standoff distance for HRET piercing?
15 to 25 feet from the fuselage
What piercing heights correspond to deck levels of a 747 or A380?
13’6”, 23’0”, and 31’0”
What is the recommended piercing location on a passenger aircraft?
10–12 inches above cabin windows
What does the acronym FLIR stand for?
Forward Looking Infrared
What is the primary goal during an aircraft fire?
Protection and preservation of life
Which foam pattern application is considered inefficient?
Raindrop application
What is the risk of using a straight stream from a turret?
Danger to personnel and disruption of foam blanket
What nozzle spray width is typical from a penetrating nozzle?
Approximately 40 feet
What is the average water weight per gallon?
8.34 lbs
What does DEVS stand for?
Driver Enhanced Vision System
What is the function of complementary agents?
Enhance firefighting with Halon, dry chem, or Halotron
What standard defines ARFF vehicle requirements?
NFPA 414
How much water does a 3000-gallon ARFF truck deliver at 250 GPM for piercing?
12 minutes
What type of container failed quickly in fire tests?
Lexan-sided cargo containers
What are common clock positions for cargo aircraft piercing?
10:00 & 2:00 (main), 4:00 & 8:00 (belly)
Why is FLIR critical in cargo aircraft fire operations?
Detects heat blooms to locate fire
What should training lesson plans include?
Specs, weight/height, agents, flow rates, SOPs, hazards
What causes ‘boom loading’ in an HRET?
Nozzle reaction during flow while the boom is held static
How does the angle of piercing affect spray efficiency?
Too steep disrupts foam pattern, misplaces spray
What are ULDs?
Unit Load Devices for cargo
What effect does water weight have inside aircraft?
Alters aircraft balance; may cause tail tip
Where is it safest to create a drain hole for excess water?
Just above the main deck rivet line
