MENU PAGE
The MENU page is divided into three sections: menu section, confirmation section and parameter readout. A
cursor on the left side of the screen is controlled by the UP/DN buttons on the EICAS control panel (ECP). The
SELECT button on the ECP is used to select a line item.
The menu list contains a single FUEL USED RESET line. When the line is selected, the ACCEPT/CANCEL
selections in the confirmation section are used to accept or cancel the request to reset to zero the “Fuel Used”
indication, on the FUEL synoptic page.
The parameter readouts section contains the engine OIL LEVEL indications.
FLIGHT DATA RECORDER
Real aircraft are equipped with flight data and voice recorders. The CRJ’s flight data recorder saves different
information for 25hrs of flight. The FDR automatically starts recording as soon as the BEACON light, STROBE
light is switched ON or a take-off-like condition is detected via the wheels. In case the pilots want to mark a
certain event, they can push the FDR event button for 2 seconds and a timestamp is saved.
The voice recorder saves the last 120 minutes of cockpit communication and passenger announcements as
soon as the aircraft is powered up.
AUTOMATIC FLIGHT CONTROL SYSTEM
The automatic flight control system consists of several systems:
• Flight Director
• Autopilot
• Flight control computers
• Two yaw dampers
• Automatic elevator trim
• Servos / actuators
The flight director computes a flight path which needs to be followed to archive certain pre-set constraints (i.e.
climb at a pre-defined speed to a pre-set altitude). The autopilot computes the required flight control’s
