Glossary of Terms - A

ATV

Amount of servo travel. For instance, 50% ATV would mean the servo's maximum travel is 50% of its physical limit.

Active View

The Active View is the view that all commands in the View menu act on. Only one view at a time is active. You can make a view active by clicking on it with the mouse. When you want to control a view's properties, you must first make it the Active View

Advanced NavGuides

A gadget that displays continuously updated information about your aircraft. The Advanced NavGuides gadget is more customizable than the NavGuides gadget.

Adverse Yaw

The tendency of an airplane to yaw in the opposite direction of the roll. For instance, when right aileron is applied, the airplane yaws to the left, thus opposing the turn. Adverse yaw is common in trainer type airplanes having flat bottom wings. It is most noticeable at slow speeds and high angles of attack, such as during takeoffs and when stretching a landing approach. Caused by the unequal drag of the upward and downward deflection of the ailerons, this undesirable trait can be minimized by setting up the ailerons with Differential Throw or by coordinating the turns, using the aileron and rudder controls simultaneously. See Differential Throw.

AFR - Advanced Flight Recorder.

A feature of RealFlight G2 that allows the pilot to not only view prerecorded maneuvers, but also to record their own maneuvers as well. During the playback of maneuvers, the pilot has the ability to select from a number of different options such as fast forwarding, rewinding, looping, speeding up and slowing down the recordings. These recordings may also be sent to others via the Internet. The pilot can also activate an onscreen transmitter to watch the stick inputs for each prerecorded maneuver.

Aileron

Hinged control surfaces located on the trailing edge of the wing, one on each side, which provide control of the airplane about the roll axis. The control direction is often confusing to first time modelers. For a right roll or turn, the right hand aileron is moved upward and the left hand aileron downward, and vice versa for a left roll or turn. 

Airfoil

This is the cross-section shape of a surface (e.g., wing) that produces lift. Airfoils usually have some sort of a "tear drop" shape.

Angle of Attack

The angle that the wing penetrates the air. As the angle of attack increases so does lift and drag, up to a point.

Anti-Roll Bar

An anti-roll bar is a wire device fitted to the car which limits, or prevents the car 'body rolling' from side to side through corners.

Anti-Squat

Anti-squat is generally used on the rear suspension of the car and refers to the angle of the rear suspension arm hinge pins in relation to the chassis. See also Caster.

Arm

This is defined as the distance from the point of attachment to the weight.

ARF

A prefabricated model - Almost Ready to Fly.

ATE - Advanced Terrain Editor

The ability to adjust the flying site in virtually any manner desired. The pilot can add trees, selecting the type, size and color; add, move, size and orient buildings, walls and other scenery objects; position and orient the runway; even choose the amount and type of lighting at the flying site. 

Auto-Play

Automatically detects when a CD-ROM is inserted and runs the specific program on the CD-ROM.

Autorotation

A maneuver in which the heli is landed without power. The momentum of the blades is enough to slow the heli prior to landing.

Autorotation Event

An event where players attempt to autorotate into a target (similar to Spot Landing). Each player takes a turn. Players collect different point amounts based on landing location. The Autorotation Event (also called a Deadstick Landing event) works for helicopters only.
