Glossary of Terms - C
CG - Center Of Gravity This is the point at which the airplane balances fore to aft, and side-to-side. The location of this point is crucial to how the airplane reacts in the air. A tail-heavy plane will be very snappy, but generally unstable and susceptible to more frequent stalls. Conversely, a nose-heavy airplane will tend to track better and be less sensitive to control inputs, but will generally drop its nose when the throttle is reduced to idle. This makes the plane more difficult to land, since it takes more effort to hold the nose up. A nose heavy airplane will have to come in faster to land safely. Camber refers to the angle of a wheel in relation to the vertical (perpendicular). 'Negative' camber means that the top of the wheel leans in towards the center of the car, whilst 'Positive' camber refers to the situation when the top of the wheel leans out - away from the center of the car. Caster refers to the angle of the front king pin in relation to the vertical. The king pin may be either a solid pin, or imaginary line through the center of the steering block. Castor is measured in degrees and generally refers to the angle which the king pin leans back from the front of the car. A typical castor angle for a two-wheel drive buggy or truck is 25 degrees. A four-wheel drive buggy may vary from 5 to 20 degrees. A mechanism on a helicopter that changes the pitch of the main blades, thereby allowing the helicopter to ascend or descend accordingly. This is the control that adjusts the pitch of the rotor blades. RealFlight G2 allows the pilot to activate Collision Detection for all of the objects. If activated, collision detection senses when an aircraft "bumps" into an object, and causes a crash. When a helicopter hovers, the blades form a slight "cone" when viewed from the side. The Coning effect is caused by the balance between lift and centrifugal forces on the blades. The Control Panel is useful for many aspects of the G2 program, including installing and uninstalling the simulator, running the simulator, online updates, and technical support. Generally defined as the portion of the wing that moves. This is usually the ailerons, elevator, rudder, flaps or spoilers. RealFlight: A device used to control an aircraft in RealFlight G2. Currently, all new versions of RealFlight G2 ship with Great Planes's USB InterLink Controller by Futaba. This device can either be used as a standalone controller, or as an interface to use your own R/C transmitter to control RealFlight. Previous versions of RealFlight shipped with either a Futaba game port controller, or a Transmitter Adapter Interface. For information on the latter two controllers, please see the manuals that came on the program CD with those versions of RealFlight. RealRace: RealRace includes a genuine Futaba pistol-grip controller to add to the Realism. Refers to the changing of a main rotor blade's pitch as the rotor head rotates. Pitch is added while the blade is pointing in one direction (e.g. while the blade is over the canopy), and removed while the blade is pointing the the opposite direction (e.g. while the blade is over the tail boom). This causes the helicopter to pitch and roll. Page last updated: October 08, 2015 Content Copyright 2015, Knife Edge Software and Great Planes. Web design Copyright 2001-2015, Knife Edge Software.
