so that the McCready arrow points to the day specific climb rate and then briefly press the
McCr /Mark key. The McCready acoustic zero point is now set to this desired McCready
position and you can fly purely with the acoustic, optimal for distance travel, and removing
the need to glance at the instrument continuously. If the McCready acoustic is switched on,
the daytypical climb shows in black, the toneless gap is shaded. If the tone lowers, then you
need to speed up and vice versa; you should keep the pointer and the tone at the same
position.
In order to offer the pilot additional help it is possible to set an acoustic dead band around
the chosen McCready ring value (this is that position of the McCrdy pointer when the user is
activating the McCrdy sound by pressing the key McCr /Mark ) This means, the pilot flies
correct according the McCrdy theory when the instrument is quiet. In the Setup menu Basic
Settings/McCready one can adjust the wideness of this dead band. (Factory setting = + - 30
cm/s) With the same key, you can set a delay in seconds for the restarting of the McCready
sound after leaving a thermal. (Factory setting = 7 seconds)
1.11 Average Thermal Climb
There are good and not so good thermal days. The average climb even varies throughout
the day. Climbing is generally better at midday than in the morning or the evening. The
Flytec 5030 GPS has, for this reason, a grey area in the double edge of the analogue vario
display which indicates the average thermal climb and is necessary for the McCready theory.
We can call this pointer average thermal climb display for a selectable time. ( See title
photo ) It is solely influenced by the climb and shows the average thermal strength for the
last 1 … 10 minutes of climbing. (adjustable at Basic Settings/Average thermal climb )
The pilot flies optimally, when the active McCready pointer, covers the end of the average
thermal climb area. (See also 5.5 – McCready Theory)
1.12 Battery Management
The Flytec 5030 GPS has a high performance NiMh (nickel metal hydride) accumulator. This
rechargeable battery can be charged with a plug-in charger (230/110 V AC), by using a
vehicle battery (10 –18 V) or by means of a solar panel. The accumulator is built into the
casing and requires no maintenance. A charging cycle (for empty batteries) is approximately
4 to 6 hrs. An intelligent charging unit in the Flytec 5030 GPS recognizes when the battery is
full and stops charging. It is therefore impossible to overcharge the battery if you forget to
unplug the charger. Nevertheless we recommend that you unplug the charger for safety
reasons when charging is complete.
A fully charged battery should last for 22 hours with both vario and GPS receiver switched
on. The battery life will be more than doubled if only the vario is used. Please bear in mind
that the battery's capacity decreases at very low temperatures. When the battery capacity
has dropped to about 10 %, an alarm tone sounds and the message “Low bat GPS off” will
appear on the display. The GPS receiver, which consumes over half of the energy, will be
shut off, and the remaining energy will be sufficient for using the vario for another 2 to 4
hours. However, if a pilot definitely wants to keep recording the GPS position, he/she can
turn the GPS receiver on again (within 30 seconds); flight recording will then continue
uninterrupted.
If a critically low voltage threshold is exceeded, the unit switches itself off. Although the
battery life indicator is temperature compensated, we recommend that you start with at least
50% of the battery capacity for longer flights. A bar graph scale shows the battery charge
level. In addition, its voltage is also measured and the remaining battery life is calculated in
hours. The indicated battery life will appear too high direct after charging.
