Very Large Air Tanker (VLAT), Bomber 912 heading back to Phoenix-Mesa Gateway Airport Phoenix, Arizona, USA after this aerial suppression operation mission on the Burro Fire, and photographed near the summit of Guthrie Mountain (6,466 feet) in the Santa Catalina Mountains. 2017.07.02

 

The DC-10’s air speed during drops is normally 278 km/h (150 knots)at about 200-250 ft.

The flow rate from the tanks is controlled by using the doors and adjusting the amount that they are opened. This is controlled by a computerized processor with programmed settings for achieving different coverage levels as dialed up on the tank controls. There are eight standard coverage level settings (1–8) on the control panel.
