Helm or pilots need to be familiar with these terms and concepts:
Types of propulsion:
Warp - Used for faster than light speeds
Impulse - Used for speeds lower than the speed of light, also called the sublight
Thrusters - Used for manuevering and for lift off
Location(with respect to your ship):
Aft- Behind
Foreward - Toward the bow or front of the ship
Port - Left
Starboard - Right
Directions:
Bearing - The direction your ship is in the XY plane. It measures the angular difference between the direction you are headed in and the direction being described.
------Relative Bearing- The direction of your ship with respect to the ship's heading (bow)
------Absolute Bearing- The direction of your ship in relation to a particular reference point. In Star Trek, the "Center of the Galaxy" is used.
Mark - The elevation or depression ( Z plane)
Types of motion of ship (not usually desired ;o) ):
Roll - Rotation about the x-axis
Pitch - Rotation about the y-axis
Yaw - Rotation about the z-axis
Phrases related to space battles or fighting
Engage - Begin fighting with another ship
Disengage - Break off fighting with another ship
Types of Pursuit:
Lead pursuit - Taking the path based on your prediction of the flight path of your target. You anticpate where it will be and alter your course to cross the target's flight path.Smaller or more manueverable craft can get an advantage by taking sharper turns.
Lag pursuit - The opposite of lead pursuit. You make a wider turn instead of a sharper one to a point just behind the tail of the target.
Pure pursuit - Following closely the path of the target.This is the position you want to be in for for torpedo and missile firing. Good also for closer range with phasers.
Fun stuff:
Slingshot effect- Use it to catapult around a star or planet by using the force of its gravitional pull and veer off at the right moment.This is great for escaping crashing into the planet with little or no power and just the use of thrusters at the last (and right) moment. If you do it just right around a star you can travel back in time (according to the original series and the original series movies) and reek havoc with the time line.
