An electrical de-icing heater element is configured around the P20/T20 probe powered by Aircraft 115V supply. The EEC selects probe heat on and off dependent upon the following?
- Probe Heat selected ON if: Aircraft is in flight and N1>10% Or Aircraft is on ground and engine is producing thrust with N3>45% and N1>10% Probe Heat is selected OFF if: Aircraft is in flight and engine is not producing thrust, with N1 < 10% Aircraft is on ground and engine is not producing thrust, with N3<45% or N1<10%. (correct)
- Probe Heat selected OFF if: Aircraft is in flight and N1>10% Or Aircraft is on ground and engine is producing thrust with N3>45% and N1>10% Probe Heat is selected ON if: Aircraft is in flight and engine is not producing thrust, with N1 < 10% Aircraft is on ground and engine is not producing thrust, with N3<45% or N1<10%.
- Probe Heat is selected ON whenever aircraft is powered ON and Probe Heat is selected OFF whenever aircraft is powered OFF
- Probe Heat is selected ON whenever aircraft is powered ON and in flight and Probe Heat is selected OFF 60 secs whenever aircraft is on ground.
