Mach .76 for Turbulence/Engine Anti-Ice ON
I have seen some pilots select Mach .76 everytime they feel some buffeting during cruise. What is really the purpose of selecting Mach .76?
I have also seen some pilots select the engine anti-ice ON even if the TAT is reading more than +10 when they anticipate that the aircraft is going inside clouds (even without precipitation and no visible moisture). When do you exactly need to turn the Engine Anti-Ice ON?
