Above Sea Level (ASL) Sensor

The pressure sensor, such as TGY-CAT01, can be configured in the System ⭢ Extra ⭢ ASL menu:

The sensor cannot compute the altitude by itself, so the computation is done inside the Tx firmware.

Setup

The default values can be set by long pressing the OK button.

A short press of the OK button is used to change between the pressure at the sea level and temperature. The Altitude is calculated as altitude above the sea level.

To set the relative altitude, set a current pressure and temperature at the start position.

Altitude is re-calculated on every value change.
