> Home Learn LK8000 Baro to GPS altitude


If an external device is providing barometric pressure altitude to the LK, and you have chosen to
"Use baro altitude" in config system setup menu 5 "Glide Computer", then all calculations will be based
upon this altitude.

There are some situations when you would like to switch to GPS altitude during the flight:
- you have a badly set QNH
- the QNH has changed a lot and you don't have any radio source available to tell you
- you think that the HBAR is wrong, and prefer to use GPS altitude
- the baro altitude source (external device) has failed, and no more altitude is sent to LK
resulting in no altitude changing, or changing periodically

In this case, a menu button "Nav by" in Config 1/3 page is available, to switch HBARHGPS quickly.
If baro altitude is not available, this button is disabled.

Another approach is to assign a customkey the Baro altitude toggle switch.
Finally, on the navboxes stripe SYS6, HBAR status is shown as ON or OFF is available.
