1. (1) Generally, when a turbine engine indicates high EGT for a particular EPR (when there is no significant damage), it means that the engine is out of trim. (2) Some turbine-powered aircraft use RPM as the primary indicator of thrust produced, others use EPR as the primary indicator. Regarding the above statements, A. only No. 1 is true.
