Cold and low operation with N1 and ITT gauges only
CRJ200 for example has non FADEC engine and only N1, N2 and ITT gauges and is flat rated to 23 degrees C. If I operate from the airport where temperature is -20 and I accidently put 20 into the FMS for N1 thrust calculation will I get any information that something is wrong and engine parameters are exceeded during takeoff roll? As I understand N1 will stay in the green range ITT will be in a green range too but certified engine thrust rating will be exceeded without any cockpit indication? Is there any risk associated with a such mistake except takeoff path looking more like F16 is departing?
