2.2: Definitions of Roller-Coaster terms: E-F
Elevated Curve
A type of curve, usually found on an Out-and-Back, where the curve
descends in height as it curves. These curves are normally banked as
well (See <<Banked Turn>>).

Exclusive Ride Time
Usually part of an organized Coaster Club's event. An "ERT" consists of
a block of time, usually before and/or after a park is available to the
<<general public>>, in which only the members of the coaster club are
allowed to ride. This allows the hard-core enthusiast more rides in less
time. Parks usually make sure their coaster(s) are running better for
such events, making them even more appealing.
Fan Curve
There are two somewhat different meanings of "fan curve" floating about.
A curved called a "fan curve" could actually meet definition 1 below, or
definition 2, or both. Confused? Good. ;^)
1. A curve with spoke reinforcements radiating from a central point to
the circumference of the track.

2. A curve that enters the turn while ascending, and exits the turn
while descending. These are usually more thrilling than a flat turn
(See <<Elevated Curve>>).

Figure Eight
Layout of a coaster resembling the numeral eight, thus allowing both
right and left turns.
Fine' Del Capo
A portion of track that quickly ducks under an overhead support in such
a way as to give the rider a feeling of imminent decapitation. Can also
refer to the portion of track that first enters a tunnel or covered
brake run. Those of you who've studied music or Italian may recognize
the term as Latin for "end of the head." :^)

First Drop
Usually the highest and most exciting drop on a coaster, most often
following immediately after the chain lift. First drops are usually
angled at about 50 degrees.

Flat Spin
B&M's reference for a highly banked, high speed helix. This element can
be found on their Sit-down, Stand-up and <<Inverted>> roller coasters.
Flat Turn
A turn in which the trackwork remains virtually flat (i.e. the opposite
of a <<banked turn>>). It usually gives the riders the feeling that the
coaster may tip over, due to <<lateral gravity>>.

Flying Turns
A term from the original trackless coaster design. This coaster
resembles a bobsled run with the trains running in a U shaped trough.
The flying turns from the 1920s and 30s used Cypress wood for its trough
and maintenance was high. Newer versions of this type use steel for the
trough.
