2.7.6 L/D req to goal = required Glide ratio to last WP of a Route
This field displays the required lift/drag ratio over ground to the goal over several waypoints.
It helps to decide whether one can fly directly over several waypoints to the goal, or whether
one must gain height within a Thermal. The calculation does not take into account if there
is an area with higher geographical altitude than the direct line from current position to goal.
Distance is calculated as in 2.6.6.3. Dist to Goal (total distance to the Goal of a Route).
2.7.7 Alt a. Goal (In total required Height to the Goal of a Route)
This user field displays the calculated altitude above goal, while taking into account all
legs of a Route still lying in front of the pilot, and by flying in accordance to best glide.
Hereby is also taken into account for all sectors the wind component strength and direction
as it was last detected. In Competition, a pilot can discern before approaching the turning
points of a task lying in front of him, if he can reach the goal without additional ascent.
In addition this function makes it possible to fly to goal as fast as possible, if speed is
selected in such a way that this field always displays the required altitude above Goal.
The more one is distant from the goal, so much higher variations this figure will show.
One could imagine to send a beam to the goal and the user field displays the altitude of
this beam above the Goal.
2.7.8 McCready-Ring
The single pointer visible in the climb range of the analogue Vario indicates the current value
of the McCready-Ring. The position of this arrow is dependent on the polar of the glider,
the wind, the rising or sinking of surrounding air, and, in particular, on the flight speed.
If a pilot wants to complete a task in the shortest possible time span, then he needs to keep
this McCready pointer by continuous adaptation of his air speed on the Variometer position
which corresponds to the average climb in Thermals. Due to the fact that this arrow
depends on various conditions, it is also designated as active McCready pointer.

9.5.2 Travel optimised Speed to
Fly according to McCready
By pressing the key McC;/WP it is possible to turn the McCready Sound on or off.
The pitch of this sound is linked to the pointer. Hereby the zero-point of the acoustic is set
to the value corresponding to the current McCready arrow at the moment of keystroke on
McCready On. Therefore adjust your speed so that the McCready arrow is congruent with
the average thermal climb rate. Then press briefly the McC;/WP key. The zero-point of
McCready acoustic is now set to this desired McCready position.
