This is a real-time communication between two or
more RealFlight 7 users which is conducted via the
PC. RealFlight 7's multiplayer feature enables a
public chat if so desired.
In many of RealFlight 7's selection windows, items
are displayed in a hierarchy format. An item that
belongs to a higher group, or parent, is considered
the child item.
The chord of a wing or surface is the width of the
surface. A wider chord offers increased lift.
However, a wider chord also generates more drag
when the aircraft rolls.
CG is the abbreviation for the phrase Center Of
Gravity. This is the point at which the aircraft
balances fore to aft and side-to-side. The location
of this point is crucial to how the aircraft reacts in
the air. For airplanes, a tail-heavy plane will be very
snappy, but generally unstable and susceptible to
frequent stalls. Conversely, a nose-heavy plane 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.
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 7 sports the most advanced collision
detection modeling ever used in an R/C model
simulation. It blankets the entire aircraft, ensuring
accurate modeling of the aircraft when it collides
with objects and items within the simulation.
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.
