time possible, then he/she may consider keeping the McCready
pointer as close as possible to the average climb rates achieved in
thermals (indicated by the Average Thermal Climb Indicator). Due to
the fact that the indicator is dependent on many conditions, we call it
an active McCready pointer. Please refer to section E5 -McCready
Theory for further explanation.
Using the 5030’s McCready sound feature the pilot can control glide
speed acoustically. The default for McCready sound is
off
each time
the 5030 is restarted. It is possible to set a dead band for the
McCready sound so that there is no McCready sound when flying at
(or near) the desired speed ring setting. To activate the McCready
sound, fly the desired speed ring setting and press the
McC
/ Mark
key once. The McCready sound will now be active with a dead band
centered on the desired speed ring setting. To move the dead band to
a different speed ring setting the pilot should fly the desired new speed
ring setting and press the
McC
/ Mark
key twice (the first press turns
the sound off and the second press turns it back on with the new
setting). The frequency of the McCready tone is proportional to the
speed ring setting that the pilot is flying (i.e., the higher the speed ring
setting that the pilot flies the higher the frequency of the McCready
tone). If the tone lowers while gliding, then you need to speed up and
vice versa. The width of the dead band can be set in ft/min (m/sec) and time delay in seconds can also be set for the
restarting of the McCready sound after leaving a thermal in Menu>Basic Settings>McCready.
A11 Battery Management
The 5030 has a high performance NiMH (nickel metal hydride) battery. The internal battery can be charged with a
plug-in wall charger (120/230 V AC), by using a vehicle cigarette lighter adapter, or by means of a solar panel (10 -18
V). The battery is built into the casing and requires no maintenance. A charging cycle (for empty batteries) is
approximately four to six hours. The intelligent charging circuit in the 5030 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. The battery has been
permanently built into the unit, and the user should not try, in any way, to replace it. In the event that a replacement
should be necessary, the unit should be sent to Flytec. We will also take care that the battery is properly disposed of,
if necessary.
A fully charged battery should last for twenty-two 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 approximately 10
%,
an alarm tone sounds, and the
message “Low bat GPS off” will appear on the display. The GPS receiver, which is responsible for over half of the
power consumption, will be shut off, and the remaining energy will be adequate to use the vario for another 2 to 4
hours. However, if you definitely want to keep recording the GPS position, turn the GPS receiver on within 30
seconds with the F1 key, and flight recording will then continue uninterrupted. If a critically low voltage threshold is
exceeded, the 5030 will switch off. Although the battery life indicator is temperature compensated, it is recommended
that you start with at least
50%
of the battery capacity for longer flights. A bar graph scale, at the top of the display,
shows the battery charge level. The measured voltage, and the remaining battery life (in hours), is also displayed.
The indicated battery life will appear high directly after charging.

The battery’s nominal voltage is 3.6 Volts, however, during normal operation the voltage is between 3.5 and 4.1
Volts.
During charging, the voltage rises to 4.4 volts. You can check the battery voltage during charging, but normally the
unit should be turned off during charging. If the unit is on while it is being charged the bar scale is replaced with
“charging”. Note: The ambient temperature should be between 50

when recharging the battery.
The yellow LED on the bottom of the unit will blink several times after plugging the unit in (to test the battery’s
condition) and will stay eluminated until the recharging is complete. If you leave the unit plugged in to the charger for
a few hours after the LED light has gone out, it will switch to trickle mode allowing the stored energy in the battery to
increase by a few percent.
