b) The flush deck nozzles should be controlled from
the instructor's station only, by activating the motorized
valve. The water demand for the 19F4 structure should not be
affected by these nozzles. Deck nozzles should not be used
simultaneously with other agents.
c) Agents used to fight aircraft deck fires should
come from the foam deck. Foam should be used exclusively to
fight aircraft fires. Water should be used to cool ordnance
after the fire is out and used to wash contaminate off the deck.
d) PKP should not be used as a firefighting agent
with this structure.
a) The wind generator should not be used because of
crosswind problems, safety, noise and power consumption.
Natural wind should be used to provide the air movement
required. In an effort to retain the advantage of training with
a upwind or downwind approach to the fire, the device should be
configured so the fire can be attacked from any one of its four
sides with equal realism. Foam decks are also located so the
fire can be approached from any side.
b) Wire mesh covered openings bordering the crawl
space should be as large as the structure will allow to provide
as much air under the fireplace as possible. Louvers and
backdraft dampers for the 19F4 trainers are not required since
neither artificial smoke nor PKP is used.
instructor's station is expected to add 1000 W to the air
conditioning load. There is no electronic equipment (device)
cooling load for the electrical space below the instructor's
station. This electrical space should be cooled and heated.
a) Artificial smoke should be used to help trainees
determine wind direction and to indicate, along with the sound
of an explosion, ordnance that has heated beyond its cook-off
