Phase III - Block VI - Aviation Life Support Systems Flashcards
What is a safety issue related to Halon?
Halon may produce decomposition by-products characterized by a sharp odor that may be harmful. Evacuation or oxygen is recommended until ventilation is established.
What should be done before servicing oxygen systems?
Make sure your hands, clothing, and all tools and equipment are clean. Clean the lines, fittings, and the surrounding area. Oxygen combines readily with oil, grease, and other petroleum products to form a combustible mass.
What does HERO stand for?
Hazards of Electromagnetic Radiation to Ordnance
Why do we use HERO for naval aircraft?
Physical contact with cartridge actuated devices during handling and loading operations is prohibited. At this time all radio transmissions and communications are halted.
Describe the oxygen system on the C-130?
Emergency oxygen is supplied to aircrew from the liquid oxygen system. Liquid oxygen flows from the 25 liter converter, located in the nose wheel well, through a heat exchanger. From there, gaseous oxygen is supplied to ten regulators located throughout the aircraft.
What is the capacity of the oxygen system?
25 liters
How many walk around bottles are on the C-130T?
4 with full face masks
Where are the walk around bottles located in the C-130T?
One is located next to the pilot and co-pilot. One on the starboard side of the 245 bulkhead and one starboard aft of the wheel well.
Explain the environmental control system?
There are two separate air conditioning systems on the C-130T.
True or False
Either system can supply conditioned air to both the flight station and cargo compartment distribution ducts and provide full pressurization capability.
TRUE
How does the air conditioning system work?
Each system refrigerates air fed to it from the bleed air supply system and conducts a mixture of hot air and refrigerated air through ducts to outlets in the aircraft compartments.
True or False
Only the cargo compartment can be pressurized using the cabin pressurization system.
False
The entire aircraft
How is the aircraft pressurized?
Pressurization is supplied from the air conditioning system, and the flow of air out of the aircraft is controlled by the out flow valve.
What happens if the aircraft is over pressurized?
If the cabin over pressurizes there is a safety valve located on the cargo door which will relieve pressure.
How many first aid kits are on the C-130T?
22
How many hand axes are on the C-130T?
3
Where are the hand axes located and why do we need an ax on the C-130T?
There is one hand ax on each side of the 245 bulkhead (port side) and 1 port aft of the cargo chain box.
The hand axes can be used during an emergency if the normal exits are blocked.
How many emergency lights are on the C-130T & what is there purpose?
There are 8 emergency lights and they are used to help identify exits in the event of crash or loss of power.
How many LRU-33 life rafts are on the C-130T?
4
How many personnel can fit on one life raft?
20
How many PRC-149 emergency radios are on the C-130T?
5
What is a VRU and how many are on the C-130T?
Victim Rescue Units and 80
How many LPU-32’s are on the C-130T?
There are 80 LRU-32 personal flotation life preservers are on-board for use by passengers.
How many Viking anti-exposure suits are on the C-130T?
5
How many escape ropes are there on the C-130T and where are they located?
3 and located next to each overhead emergency escape hatch
How many 2 gallon emergency portable water containers on the C-130T?
10 located next to the cargo ramp
True or False
The aircraft fire suppression system provides fire protection for each of the four engines and the APU?
TRUE
What is the fire extinguishing agent used in the fire suppression system?
Bromotrifluoromethane
How many bottles and what is the capacity of each bottle?
2 & 27 pounds
If there was an engine fire how is it extinguished?
The bottles are discharged one at a time and the agent is able to be directed to any one of the engines or to the APU.
How do the fire bottles work if they are needed to extinguish a fire?
Each bottle is supercharged with nitrogen at about 600 PSI and is discharged by an electrically exploded charge from a cartridge actuated device.
How many fire extinguishers are there on the C-130T and where are they located?
4
One located on each side of the 245 bulkhead (port side), one on the port aft wheel well, and one port aft of the paratroop door.
