Instructions:
The steam catapult fires the F-18 down the aircraft carrier runway to takeoff speeds.
Adjust the main valve based on the F-18's weight, including weapons and fuel.
The wind speed also makes a big difference on the proper setting of the main valve.
Too little main valve and the F18 will be too slow.
Too much main valve forces the F18 to accelerate too fast and might even rip off the landing gear!
Also watch out for changing steam pressures (happens at higher ranks)
Adjust with more main valve when the steam pressure is low and vice-versus.

Get to know your catapult and achive higher ranks!
