Stevens Posted January 10, 2022 Report Share Posted January 10, 2022 When i have preset the aircraft, ATS window shows N1 TO, started the engines and switch on Cowl Anti-Ice on, ATS window shows FAIL. When I clear the FAIL message, I cannot reengage ATS, the window stays blank. Once I switch off Cowl Anti-Ice, N1 TO is back on without even doing anything! I reproduced it several times. Is this normal system behaviour? This only happens on ground. Once airborne, I can switch on Anti-Ice, ATS stays on. Thanks for clarification and for an Info here.

mesae Posted January 15, 2022 Report Share Posted January 15, 2022 This is expected. If you will takeoff with cowl anti-ice you need to tell the FMS so in PERF INIT TAKEOFF REF 2/4. Quote Link to comment Share on other sites More sharing options...
Jakobb Posted April 10, 2022 Report Share Posted April 10, 2022 I just had the error twice as well shortly after getting airborne. No N1 setting was selectable when AI was on. I beleive climb power was selected Quote Link to comment Share on other sites More sharing options...
