Questions and answers

What air pressure and electrical condition are required before MAFFS servicing procedures?

Before proceeding with steps 1 through 11, high pressure air gauge must indicate a minimum of 600 PSI and electrical power must be connected. (paragraph 7)

What happens if electrical power fails during retardant filling?

If electrical power fails during filling operations, shut off the retardant fill line immediately.

What is the maximum discharge pressure setting during fluid transfer?

Limit maximum discharge pressure setting to 30 PSI during fluid transfer, or lower drop setting. (paragraph 7)

What must happen if the drop valves close prematurely?

Any premature closure of the drop valves may indicate a problem which could result in hazardous over-pressurization of the discharge tubes. Discontinue system use and investigate cause in accordance with the MAFFS maintenance manual. (paragraph 3)

What must be done to avoid an adverse center of gravity during flight?

The drop sequences specified must be followed to avoid adverse center of gravity during flight.
