Flying in icing conditions above FL300 in the Phenom 300
Greetings from the South of France,
Well, the flight manual specifically indicated that with negative temperature in visible moisture all Anti-ice should be turned on. I did not think that this was an issue until flying last month to the Maldives (VRMM) en encountering IMC conditions from 10000 feet up to FL450. We did turn everything anti-ice protection on and got the TTO heater fail message which is a known situation from Embraer. The reason for this is the current "logic" which does turn the TTO heater off rather and an actual failure. However, the recommended procdure is to "exit" icing conditions as ice could accumulate on the probes and then get into the engine with potential damage.....
"Getting out of the "Icing conditions" was not truly possible, thus our demand to Embraer who confirmed been actively working on this with a new "logic" load which will allow for Engine anti ice at any altitude.
All the best,
