The Extended Range (ER) version of the King Air 350 increases the gross weight by 1,500 lbs. through substantially larger and stronger main landing gear struts/wheels/tires & brakes, and increases the fuel capacity by 236 gallons/893 liters to a total of 775 gallons/2,934 liters through use of low drag metal fuel tanks aft of the powerplants. Higher gross weight and higher fuel capacity result in significantly more mission flexibility.
