Livery – a certain paint scheme for an aircraft. Different liveries can be selected in X-Plane to give
an aircraft a different paint job.
Pylon – a hard point on an aircraft, where things like engines or weapons can be mounted.
Reference point – the arbitrary point of the aircraft around which nearly all objects’ positions
are set.
Root (of a wing) – the part of an aircraft’s wing which is closest to the fuselage (body) of the
aircraft.
Rudder – control surfaces mounted on an aircraft’s vertical stabilizer (a part of the tail) which
move in opposite directions to change the yaw of the craft.
Slat – control surfaces mounted to the leading edge of a wing which extend to allow the aircraft
to operate at a higher angle of attack, useful when near stall speeds.
Speedbrake – a type of flight control surface used on an aircraft to increase drag or increase the
angle of approach during landing.
Standard atmosphere – the International Civil Aviation Organization (ICAO) defines the standard
atmosphere at mean sea level to be 15C (59C) with 1 atmosphere air pressure.
Sweep (wings) – the angle forward or backward that the wing points, when seen from above, as
seen in Figure 5.
Tip (of a wing) – the part of an aircraft’s wing which is farthest from the fuselage (body) of the
aircraft.
