EngineThe EMB-145 Family of aircraft generally come equipped with two Rolls-Royce AE 3007 series turbofan engines. The engines have a bypass ratio of 5:1. The engines are controlled by two FADECs (Full Authority Digital Engine Controls). The FADECs control virtually all aspects of the engine and send engine data to be displayed on the EICAS for the pilot.

AvionicsThe Embraer ERJ 145 Family typically comes equipped with the Honeywell Primus 1000 Avionics suite. The suite normally consists of five CRT displays units (DUs) or screens. From left to right, the system consists of a Primary Flight Display (PFD), Mult-Function Display (MFD), Engine Indication and Crew Alerting System (EICAS), Multi-Function Display (MFD) (Copilot) and Primary Flight Display (PFD) (Copilot). The DUs are normally CRTs but can be upgraded to lighter LCD displays. These upgraded DUs also have added functionality.
