/** Encapsulates various uncategorized scheduled functions.
+ Pilot sensed accelerations are calculated here. This is used
+ for the coordinated turn ball instrument. Motion base platforms sometimes
+ use the derivative of pilot sensed accelerations as the driving parameter,
+ rather than straight accelerations.
+
+ The theory behind pilot-sensed calculations is presented:
+
+ For purposes of discussion and calculation, assume for a minute that the
+ pilot is in space and motionless in inertial space. She will feel
+ no accelerations. If the aircraft begins to accelerate along any axis or
+ axes (without rotating), the pilot will sense those accelerations. If
+ any rotational moment is applied, the pilot will sense an acceleration
+ due to that motion in the amount:
+
+ [wdot X R] + [w X (w X R)]
+ Term I Term II
+
+ where:
+
+ wdot = omegadot, the rotational acceleration rate vector
+ w = omega, the rotational rate vector
+ R = the vector from the aircraft CG to the pilot eyepoint
+
+ The sum total of these two terms plus the acceleration of the aircraft
+ body axis gives the acceleration the pilot senses in inertial space.
+ In the presence of a large body such as a planet, a gravity field also
+ provides an accelerating attraction. This acceleration can be transformed
+ from the reference frame of the planet so as to be expressed in the frame
+ of reference of the aircraft. This gravity field accelerating attraction
+ is felt by the pilot as a force on her tushie as she sits in her aircraft
+ on the runway awaiting takeoff clearance.
+
+ In JSBSim the acceleration of the body frame in inertial space is given
+ by the F = ma relation. If the vForces vector is divided by the aircraft
+ mass, the acceleration vector is calculated. The term wdot is equivalent
+ to the JSBSim vPQRdot vector, and the w parameter is equivalent to vPQR.
+ The radius R is calculated below in the vector vToEyePt.
