A6 Sounds and Volume Level
Each time the key
/
Menu
is pressed briefly the volume level is increased by
25%.
The adjustable sound levels are: 0
-
25%
-
50%
-
75%
- 100%. The value of the chosen volume level is displayed in the
Information Display
. All of the
sound effects described in this section can be heard in the simulation mode.
Automatic volume control:
The basic sound levels of
25%, 50%,
and 75% will slowly increase automatically once
the airspeed exceeds 25 mph (40 km/h) but never greater than 100%.
Ascent Tone:
The ascent tone starts when the climb rate exceeds a predetermined threshold. The ascent tone
threshold (the lift value that must be exceeded to start the ascent tone) can be changed in Menu>Basic
Settings>Vario audio threshold. The greater the threshold value the greater the lift needed to initiate the ascent tone.
It is possible to set the frequency of the ascent tone between 600 and 1400 Hz. As stronger lift is encountered the
frequency of the ascent tone will increase at a predetermined rate (
Modulation
). The
Pitch
is the tone-pause ratio
(beep…beep…beep) and is 1:1 for the ascent tone. All of these variables may be adjusted in Menu>Basic
Settings>Vario tone.
Modulation:
The rate at which the frequency of the ascent tone increases as increased lift is encountered is called
modulation. The modulation of the ascent audio can be adjusted to values from two to nine
under
Menu/Basic
Settings>Vario tone>modul. The higher the value, the faster the frequency will increase as the lift values increase. A
modulation setting of nine will yield more audible change at lower climb rates making it best suited for use in mild lift.
Conversely, a modulation of two will yield more audible change at higher climb rates, which will be better suited for
strong lift flying. The factory setting is five.
Sink tone:
The sink tone (alarm) is continuous and decreases in frequency as the sink rate increases and increases
in frequency as the sink rate decreases. The sink alarm can be toggled on and off by briefly pressing the
/
Route
key. When the sink alarm is turned on, the 5030 will sound a sample tone and the analog vario display will show the
sink alarm threshold. Under Menu>Basic Settings>Sink tone threshold
you can choose the threshold at which the
sink alarm will sound. The pitch of the sink alarm can be changed under Menu>Basic Settings>Vario tone>
sinktoneF.
Acoustic Integrator:
dampens irregular sound patterns during rapid vario movements (piano effect). The settings
are from 1 to 35 and the factory setting of 8 can be changed under Menu>Basic Settings>Vario tone>audio damp.
High values result in a smoother but somewhat delayed sound pattern.
Changeable beep:
The vario beep can be set so that the frequency can change during a beep. This feature will
allow you to instantly hear if the lift strength changes with out waiting for the next beep and can be set in menu>Basic
Settings>Vario tone>beepch (0= no change within a beep, 1= frequency change within a beep).
Pitch:
By altering the pitch value (between 1 and 7) the user can customize the beep/pause length. A pitch setting of
one will yield a longer beep with a longer pause between beeps while a setting of seven will yield a shorter beep with
a shorter pause between beeps. The pitch value may be set
under
Menu>Basic Settings>Vario tone>Pitch.
Stall alarm:
This is a tone of medium frequency with a very fast interval rate and is always at full volume (100%).
This sound is not adjustable. The threshold speed and altitude for the stall alarm can be set under Menu>Basic
Settings>Stallspeed. To turn off the stall alarm set the threshold speed to 0. For more details read section E1 -Stall
Alarm.
McCready tone:
When gliding with McCready sound activated, a tone is heard that corresponds to the McCready
speed value (speed to fly). This tone has been chosen so that it should not be confused with the normal ascent tone.
It has a tone-pause ratio of 1:4. For more detail read E5 -McCready Theory. This sound is not adjustable.
Negative McCready warning tone
is a deeper tone with a rapid interval sequence, which tells the pilot that he/she is
flying slower than best glide speed and that they should fly faster immediately. This sound is not adjustable.
A7 User-selectable fields
There are a total twenty-four measured values (listed below) from which the user can choose to customize the display
of the 5030. When using the vertical bar analog scale the 5030 can be configured to show either six or four user-
selectable fields. When the dial analog scale is selected the 5030 can be set to show either five or seven user fields;
four or six in the lower part of the display and one just under the altimeter 1 field. There are a total of three pages of
