petermaxkoller 30 Posted May 13, 2021 Share Posted May 13, 2021 Hi all Very happy with the CRJ 700 flying on VATSIM. As controller I have the Thrustmaster TCA Airbus. Calibrated including the reversers with the inbuilt calibration page in the CRJ tablet; works very good. When I switch on the two engines, N1 goes to about 20% idle, very good. Then I switch on the Anti-ice ON allready on ground, the engines N1 goes up to 45% N1. Switching Anti-ice OFF returns to 20% N1. Is this normal or schould I only put Anti-Ice ON during flight? Thanks Peter Link to comment Share on other sites More sharing options...
Nico Hartmann 7 Posted May 13, 2021 Share Posted May 13, 2021 For what I know, the N1 should not be linked to whether or not anti ice ist s enabled. But i think anti ice is switched on during takeoff (affects perfomance calculations) under certain icing conditions, otherwise is kept off while not in flight Link to comment Share on other sites More sharing options...
KuntaKinte 210 Posted May 13, 2021 Share Posted May 13, 2021 The attached table shows the correct usage of the anti-ice system. As for the engine RPM: In flight and only when selecting WING A/I ON the engine idle RPM is raised automatically by the FADEC to ensure that the airpressure in the pneumatic duct is sufficient for effective wing anti-icing. This results in a considerable increase of idle thrust. On ground, the selection of COWL A/I and/or WING A/I has no influence on engine RPM. Unfortunately, this is not modeled correctly. COWL ON OFF On ground Temp- <= 10°C If not required AND visible moisture OR OR contaminated surface Entering parking stand In flight In icing conditions If not required OR ICE message WING ON OFF On ground Temp- <= 5°C If not required [AND visible moisture OR contaminated runway] OR AND for takeoff only After landing (leaving the runway) In flight [In icing conditions AND IAS < 230 KIAS] If not required OR ICE message Edit: Copyright reasons - sorry Link to comment Share on other sites More sharing options...
