Glossary of Terms - D
A term used to describe non-powered flight (glide) when the engine quits running. See Autorotation Event. Ailerons that are set up to deflect more in the upward direction than downward are said to have Differential Throw. The purpose is to counteract Adverse Yaw. The V-shaped bend in the wing. Typically, more Dihedral causes more aerodynamic stability in an airplane, and causes the rudder to control both the roll and yaw axis. This is why some trainers and sailplanes require only 3 channels of radio control (i.e., have no ailerons). This is using your own radio to completely control the aircraft. This usually means you have a separate radio program on your radio for each aircraft that you want to fly with this method. All mixing and radio functions are performed on your radio and RealFlight simply passes the values directly to the aircraft servos. This is in contrast to the Joystick Emulation Interface. DSC - Direct Servo Control This radio feature permits you to check servo operation without broadcasting a radio signal. A cable connects the transmitter to the receiver. Direct servo control is very useful for on-the-ground control checks. Used to render the 3D image when you have an accelerated graphics card. It works best on faster computers. A technology created by Microsoft that controls graphics and sound operations. Blends the pixels together to produce a smoother image. This can also simulate colors that may not be available to you. This is the downward angle of the engine in relationship to the centerline of the airplane. Down Thrust helps overcome the normal climbing tendency of flat bottom wings. A software program that controls a card (e.g., video or sound card) in your computer. The card's manufacturer usually provides its Driver as well. Manufacturers frequently update their Drivers to fix bugs, or make their cards compatible with new software and hardware. You can often find an updated driver for your video or sound card by visiting the web site of the card's manufacturer, and following links to "Drivers," "Support," "Downloads", or "Upgrades." Drop refers to the amount your suspension arms hang
