The last foot of the edges will be tapered upwards to connect with the higher level to prevent a tripping hazard. A gate valve will be added to the weir drain with a recessed handle that can be closed allowing water to pool in the pit covering the concrete to prevent spalling then opened allowing all water to be drained. Pit currently has an environmental liner, layer of sand, piping and then large rock. Fill the pit with base material (over existing rock) 6” at a time compacting each time. Fill with an 8 inch concrete, reinforced with 3/4 inch rebar. The existing weir drain will be raised to the new concrete height.

The running engine fire shall produce an intense jet of flame, 2 feet in diameter, extending 12 to 15 feet horizontally from the engine’s exhaust. To extinguish the running engine fire, the fuel shut off switch in the cockpit must be secured. The fire will then be fought as a non-running engine fire. Low wing will also have a simulated 3-D fire spilling into a 10 x 10 ground pool burn area.

(b) High wing structure shall be located on the right side of the fuselage and will accommodate a prop engine fire. This prop will be used for a non-running engine fire. It will also have the piping in place to accommodate the possible use hydrocarbon fuel fires in the future.

The smoke generator shall shutdown automatically in the event of internally detected excess temperature.

(d) The aircraft mockup shall be provided with a ventilation system capable of a minimum of one air change per minute of the trainer. It shall be rated at a minimum for continuous duty with air at 500 degrees F.

(e) The ventilation system shall operate at PURGE flow when the training system is turned on and when an emergency shutdown occurs. When the trainer's Operate Power switch is turned on, the ventilation system shall operate for 30 seconds to purge the structure of any accumulated smoke or propane. During this time, all power to the trainer structure, except for the propane detection system, shall be inhibited.

(f) The ventilation system shall also operate at maximum flow during any manual or automatic emergency shutdown of the trainer, such an excessive unburned propane level detection or hardware malfunction shutdown, and shall remain on until 30 seconds after the emergency condition is corrected.

(g) Vent fan operation shall be monitored. A vent fan failure shall initiate an emergency shutdown to disable fire trainer operation.

(h) Interlocked pilot light system monitoring. A flame monitor shall I be used to detect the presence of the pilot flame. If the pilot flame fails to confirm the training fire shall be disabled from operation.

(i) Propane Level Monitoring. A drawn sample propane detection system shall continuously sample air from two locations in the fuselage mockup structure. Passive diffusion type sensors shall not be acceptable for use in monitoring propane levels within the fuselage mockup structure. The drawn sample detection system shall include particulate and moisture coalescing filters in the sample lines. Vacuum pump operation shall be monitored and the system shall initiate an emergency shutdown in the event of a pump failure or restricted sample lines. Should propane concentrations within the fuselage mockup structure reach 10 percent LEL (Lower Explosive Limit of propane in air), the ventilation system shall activate to increase air flow to the interior training fires and improve propane combustion. If propane concentrations continue to rise and exceed a 25 percent LEL, all gas supply valves shall close and the ventilation system shall activate and the vent fan shall remain on for a minimum of 30 seconds after the propane level is reduced below the 1 0 percent LEL.

(j) Burn Room Temperature Monitoring. A thermocouple shall be used to monitor the interior temperature of the aircraft mock up at the 5-foot level. The thermocouple shall have a lower safety limit of 500°F, and an upper safety limit of 700°F. When the interior temperature rises above 500°F, the ventilation system shall be forced on and remain on until the temperature drops below 500°F. If the cabin temperature rises above 700°F, the burners and smoke generator shall shut down, and the ventilation system shall remain on until the fire training compartment cools to below 500°F.

(k) Interlocked pilot light system boxes will be of double wall water jacket stainless steel construction and located as not to impede training.

(l) A new control panel installed constructed of stainless steel. The control console will provide controls for all fires as well as safety monitoring systems. Ability to conduct emergency shutdown using an “E Stop” will be required.

(m) Run and connect all required wiring from control panel to each of the interlocked pilot light boxes.

(n) Extend and connect required air piping from blowers to the interlocked pilot light boxes. This piping shall be schedule 80 PVC piping minimum.

Fires will be activated by switches on the control panel.

(p) Provide water lines from existing source at the control stand to each interlocked pilot light for cooling. An additional water line will be ran to the mock-up and connected to the framing system to provide cooling. A cooling water spray system shall provide a high volume spray with a minimum of 100 gpm @ 60 psi to the outside of the mockup. A pit fill line with a quarter turn valve will be run; the purpose of the pit fill is to cover the concrete to prevent spalling.

(q) A new control panel insert will be installed in the existing stainless steel control console providing controls for the engine fire, interior fire and fuel spill fire. The existing ability to conduct emergency shutdown using an “E Stop” will be retained.

(7) Trainer Fire Operation;

(a) The control system shall allow all training exercises to be concurrently selected and initiated by the operator using the control panel located at the control pad or control building. The operator shall be able to immediately stop any exercise should the need arise. The operator shall, through radio communications, control fire operation in response to instruction from the instructor/safety officer at the mockup. The instructor/safety officer shall enable fire operation using a "dead man" function switch.

(d) APU fire. Located on the High Wing side in the front of wheel.

(e) The low-wing engine fire shall provide training in control and extinguishment of fire in a turbofan engine that occur both when the engine is running and when the engine has been shut down. The wing engine mockup shall be located at the wing tip, right side of the fuselage. The fire shall be independently exercisable. The running engine fire shall produce an intense jet of flame, 2 feet in diameter, extending 12 to 15 feet horizontally from the engine's exhaust. To extinguish the running engine fire, the fuel shut off switch in the cockpit must be secured. The fire will then be fought as a non-running engine fire.

(f) Fuel Leak Fire. The three dimensional fuel leak fire shall consist of a representation of an ignited fuel leak from the wing engine mockup leading to a fuel spill fire on the ground in the back of the left wing engine. The fire shall be selectable to run in conjunction with the non-running wing engine fire. The fuel leak representation shall produce a cascade fire falling a minimum of three feet below the engine into the fuel spill. The fuel spill fire shall be recessed as necessary into the aircraft fires trainer's concrete pad. The cascade portion of the fire shall respond to manual control. The fire shall engulf the fuel spill area. The fire will grow at a fixed rate, and produce flames up to 12 feet in height. The cascade fire shall extinguish only when the wing engine emergency fuel shut off switch in the cockpit has been activated.

(g) The high-wing engine fire shall provide training in control and extinguishment of fire in a prop engine that occur both when the engine is running and when the engine has been shut down. The fire shall be independently exercisable.
