Variometer settings

The Flytec Balloon 4 indicates vertical speed numerically, graphically and also acoustically. This section explains how to configure both its vario acoustics, and the vario's sensitivity to vertical movement.

Accessing vario settings

Long press KB ok.png, then use KB up down.png to select Vario, press KB ok.png

Acoustic

The acoustic settings determine in which situations the vario beeps, and how those beeps sound. Inside the Vario menu, select Acoustic and press KB ok.png to get here.
Note: As a shortcut, simply long press KB audio.png to quickly get to the vario acoustics settings.

Audio general

Inside the Acoustic menu, select Audio general and press KB ok.png to get here.

Audio mode

Determines whether the vario beeps all the time, or only in flight. In the Audio general menu, select Audio mode and press KB ok.png to get here. Use KB up down.png to adjust the value. Select one with KB ok.png or cancel with KB time.png.

Base tone

Determines the pitch of the vario beep at 0 m/s. In the Audio general menu, select Base frequency and press KB ok.png to get here. Use KB up down.png to adjust the value. Select one with KB ok.png or cancel with KB time.png.

The frequency is set in Hertz, default is 800 Hz.

Tone change

Determines the way the tone changes with increasing vertical speeds. In the Audio general menu, select Tone change and press KB ok.png to get here. Use KB up down.png to adjust the value. Select one with KB ok.png or cancel with KB time.png.

  • linear: The frequency increase and decrease are linear to the vertical speed
  • harmonic: The frequency increase and decrease are adjusted to how we hear musical notes (which is not linear to frequency).

Tone rise

Determines whether and how fast the tone frequency increases or decreases with vertical speed. In the Audio general menu, select Tone rise and press KB ok.png to get here. Use KB up down.png to adjust the value. Select one with KB ok.png or cancel with KB time.png.

  • off: The frequency does not change. The vario will always beep at the base tone frequency, regardless of vertical speed. Use this in connection with clear cadence changes if your hearing is limited to a small frequency spectrum.
  • slow: The frequency increases or decreases slowly with vertical speed.
  • medium: The frequency increases or decreases at a medium rate with vertical speed. This is the default setting.
  • fast: The frequency increases or decreases quickly with vertical speed. Use this to clearly distinguish between different climb or sink rates acoustically.

Cadence change

Cadence determines the number of beeps per time unit. A high cadence means fast beeping, a low cadence means slow beeping. In the Audio general menu, select Cadence change and press KB ok.png to get here. Use KB up down.png to adjust the value. Select one with KB ok.png or cancel with KB time.png.

  • linear: The cadence increase and decrease are linear to the vertical speed
  • logarithmic: The cadence increase and decrease are pronounced at low vertical speeds, and reduced at high vertical speeds. This way the vario seems less "nervous" in high vertical speeds.

Climb tone

The climb tone is an acoustic signal that only sounds when the vario's altitude is increasing. It is a beep of varying frequency and cadence depending on vertical speed. Inside the Acoustic menu, select Climb tone and press KB ok.png to get here.

Active

Determines whether the vario produces a climb tone or not. In the Climb tone menu, select Active and press KB ok.png to get here. Use KB up down.png to adjust the value. Select one with KB ok.png or cancel with KB time.png.

  • yes: The vario produces a climb tone
  • no: The vario does not produce a climb tone

Threshold

Defines the minimum ascent speed necessary to produce a vario beep. In the Climb tone menu, select Threshold and press KB ok.png to get here. Use KB up down.png to adjust the value. Select one with KB ok.png or cancel with KB time.png.

Select a value between 5 cm/s (10 fpm) and 20 cm/s (40 fpm). Default is 10 cm/s (20 fpm).

Sink tone

The sink tone is an acoustic signal that only sounds when the vario's altitude is decreasing. It is a beep of varying frequency and cadence depending on vertical speed. Inside the Acoustic menu, select Sink tone and press KB ok.png to get here.

Active

Determines whether the vario produces a sink tone or not. In the Sink tone menu, select Active and press KB ok.png to get here. Use KB up down.png to adjust the value. Select one with KB ok.png or cancel with KB time.png.

  • yes: The vario produces a sink tone
  • no: The vario does not produce a sink tone

Threshold

Defines the minimum descent speed necessary to produce a vario beep. In the Sink tone menu, select Threshold and press KB ok.png to get here. Use KB up down.png to adjust the value. Select one with KB ok.png or cancel with KB time.png.

Select a value between -5 cm/s (-10 fpm) and -100 cm/s (-200 fpm). Default is -10 cm/s (-20 fpm).

Sensitivity

The sensitivity setting determines how finely the Flytec Balloon 4 reacts to changes in air pressure. The more sensitive it is set, the more it will also react to turbulences. Inside the Vario menu, select Sensitivity and press KB ok.png to get here. Use KB up down.png to adjust the value. Select one with KB ok.png or cancel with KB time.png.

  • low: The vario filters out most turbulence, and reacts relatively slowly to changes in altitude nor to changes in climb or sink rate.
  • regular: This is the default, with some filtering. The vario reacts quickly to changes in altitude or to changes in climb or sink rate.
  • high: The vario filters nearly no turbulence, and reacts very quickly to changes in altitude or to changes in climb or sink rate.
