Start the Engines

You can observe the engine start on the two dark EICAS displays (in the middle of the Main Panel) and also on the standby engine indicator (SEI) just left of the two EICAS displays. The full procedure for normal engine start will be covered in later sessions. For this session we will start the engines simply by pressing "E" or "Ctrl-E" (for "Engine"). You may hear the engine start on your speakers - if not, increase the volume (or put the mute to off: Ctrl-F2 or "Q").

• Check thrust levers at idle: open the Control Stand and check that the thrust levers are at IDLE (i.e. fully back - controlled by the left wheel on the base of the joystick, or the thrust levers).
• Set Parking Brakes and

Return to the Main Panel

• Press "E" or "Ctrl-E" (for "engine"). This will start the engines, which you may hear (through your speakers) and see on the EICAS displays on the Main Panel (a few seconds after you press "E").

Note that the Park Brakes are ON (bottom of screen) before the engines start. You have already moved the thrust levers back to IDLE to minimize thrust when the engines are running and the parking brakes will prevent movement. With high thrust, however, the aircraft may move even if the brakes are ON. During the engine starts, the EICAS will show the engine indications + crew alerting system (with amber abnormal indications to alert the crew) and, when the engines are stable and all is OK, the amber crew alerts will disappear.

On this 757 model, the main indicators of thrust being produced are the Engine Pressure Ratio (EPR) and N1 (pronounced "eaper" and "ennone"). These thrust indications are displayed on the Primary EICAS (the top one) and also on the SEI (standby engine indicator), and are controlled by the thrust levers. Both EPR and N1 are indications of thrust from each engine and you can see this by moving the thrust levers. The engine indications on the EICAS and on the SEI may differ a little due to the different indication systems. (Note: Even with the brakes ON, high thrust may move the aircraft - avoid this!)

During engine start have a look at the Overhead Panel, you can see each engine start selector moving to ground and to off during the start, or at the Control Stand, where you can see the two Fuel Controls (below the thrust levers) being switched on in the engine-start procedure to introduce fuel flow (FF) to the engines and being switched off when you are cutting the engines.

Once again, always return to the Main Panel.
