In 1994, Air Spray introduced the first L-188 Electra air tanker to Canada. The L-188 Electra "Long Liner" is presently the fastest initial attack air tanker in service today. It is fast during initial dispatch with no required warm up time, it cruises at 380 MPH and its maneuverability makes it the fastest large air tanker while working over a fire.

The L-188 "Long Liner" is equipped with the Air Spray Constant Variable Flow Tank System. The Constant Variable Flow Tank System is an entirely new computerized system which consists of a single 3000 US gallon tank with a computerized door.

The system can string out a "long line" or drop its entire 11365 liters in under 3 seconds. The system is so precise it can deliver any volume, coverage level or line length exactly as requested with a simple turn of a switch at the pilots finger tips! The Constant Variable Flow System produces a longer stronger line of retardant or foam since there are no weak spots created by multiple door drop sequences.
