    (b) a system that only discharges foam must--

    (1) Have enough foam agent to discharge foam continuously for at 

least 5 minutes at maximum discharge rate;

    (2) Have at least the amount of foam agent needed to cover an area 

equivalent to the swept rotor area of the largest helicopter for which 

the deck is designed with foam at--

    (i) If protein foam is used, 6.52 liters per minute for each square 

meter (.16 gallons per minute for each square foot) of area covered for 

five minutes;

    (ii) If aqueous film forming foam is used, 4.07 liters per minute 

for each square meter (.1 gallons per minute for each square foot) of 

area covered for five minutes; and

    (3) Be capable of discharging from each hose at 7 kilograms per 

square centimeter (100 pounds per square inch) pressure--

    (i) A single foam stream at a rate of at least 340 liters (90 

gallons) per minute; and

    (ii) A foam spray at a rate of at least 190 liters (50 gallons) per 

minute.

    (c) Each system must have operating controls at each of its hose 

locations, be protected from icing and freezing, and be capable of 

operation within 10 seconds after activation of its controls.

    (d) Each system must have at least one hose at each of the two 

access routes required by Sec.  108.235(f) of this part. Each hose must 

be reel mounted and long enough to cover any point on the helicopter 

deck. Each hose that discharges foam must have a nozzle that has foam 

stream, foam spray, and off positions.
