PROBE HEAT

Ground:Probe heater failure, monitor

ing system failure, or one/both AOA

probe heaters have shut off to prevent

overheat

Ground:Place PROBE HEAT switch to OFF for

1 minute (caution light goes off when OFF is

selected); then reselect PROBE HEAT. If caution

light comes on simultaneously with reselection

of PROBE HEAT, a probe heater or monitoring

system failure has occurred. If caution light does

not come on when PROBE HEAT is reselected,

one/both AOA probe heaters were shut off to

prevent overheat

In flight:Probe heater(s) or monitoring

system failure

In flight:Place PROBE HEAT switch to PROBE

HEAT, if required, and avoid areas of known or

suspected icing conditions
