NOTE
The STAL HT OFF caution message is displayed when the
Pitot heating is switched OFF, or STAL HT FAIL when there
is a failure of the stall warning heating system. Operation of
the stall warning heating on the ground also causes the stall
warning heating failed caution message to be displayed. In
this case it indicates the activation of the thermal protection
relay, which prevents overheating of the stall warning heating
system on the ground. This is a normal function of the
system.
If in icing conditions:

3. Leave icing zone/refer to 3.13.4 - UNINTENTIONAL FLIGHT INTO ICING.
