Nothing, except overtorquing the engines prior to reaching column switches(92%) for AFX. KA200's with AFX often suffer the same problem. Easy fix FO flies the leg captain holds AFX in test positon bypassing the column switches
[QUOTE=Virtually There;9084270]Law of thermodynamics anyone?
Why do ITT and fuel flow both increase for the same torque when intake flow is restricted? Because you have less mass airflow to maintain torque, add fuel to increase mass flow itt rises due to less cooling air. put EAI "on" your rpm and temp will remain the same, torque will drop. to maintain the same torque you must increase N1
This is because the extra mass airflow entering the compressor is tiring to slow it down. To maintain it set condition of n1 speed an increase of Wf is required. This now will increase itt. Same can be shown when a airconding compressor is turned on. What happens. ?
