EFIS MENU Normal Operation 1/20 EFIS MENU Normal Operation 2/20 When you initially enter the cockpit, all the EIS displays are normally off. The displays require AC electrical power to operate, so unless either the APU or a ground electrical supply are available the displays will not operate. We will connect a ground electrical supply for you. EFIS MENU Normal Operation 3/20 Once AC power is available the displays can be switched on. First, let’s switch on the PFD. Click on the PFD brightness control to turn the PFD on. EFIS MENU Normal Operation 4/20 Once AC power is available the displays can be switched on. First, let’s switch on the PFD.

EFIS MENU Normal Operation 9/20 Both the ND brightness and the Weather radar brightness are normally set to full bright at the same time. The brightness levels of both EFIS screens are later adjusted to suit the ambient light conditions. Just like the PFD after a short delay, the display will be visible but limited to failure flags because there is no data from either the ADIRS or the FMGS. You will see how the information changes on the PFD and ND as the ADIRS and FMGS come on line later in the course. EFIS MENU Normal Operation 10/20 The ADIRS system is now switched on and the PFD will display attitude, speed, and altitude data. Notice that the indication on the Altimeter scale is showing a negative value because the wrong QNH is set. The correct QNH is 1013, so the Baro setting knob, on the EFIS control panel, is rotated to change the setting. Clliicckk oonn tthhee Baarroo sseettttiinngg kknnoobb ttoo sseett QNH 11001133..

EFIS MENU Normal Operation 13/20 The setting of the ND mode selector and range will depend on the departure profile. This will be discussed in the FMGS modules but we have already set ARC and 10 miles for you. The QNH is set and the negative indication has been removed from the altimeter scale. EFIS MENU Normal Operation 14/20 When the ADIRS system is fully aligned and the FMGS is programmed, the data displayed on the PFD and ND will be more complete. The choice of which additional information selector is used will depend on the departure but normally the pilot flying has CSTR selected. Seelleecctt CSTTR..

EFIS MENU Normal Operation 17/20 The selection of the VOR/ADF selectors will depend on the nav aids used for the departure. This will be discussed in the Navigation modules. Now, let’s look at another selection on the EFIS control panel. A green indicator illuminates in the pb sw to show that you have selected it. EFIS MENU Normal Operation 18/20 An automatic function that occurred as the aircraft was powered up was that the Flight directors were switched on. This automatic function occurred because the normal mode of operation on the A320 is with Flight Directors on. Notice that the green indicator on the Flight Director pb is illuminated and that there are indications in the top right hand corner of the PFD. Look carefully at the PFD. This indication tells you that Flight Director 1 (Captain) and Flight Director 2 (First Officer) are switched on. EFIS MENU Normal Operation 19/20 Notice that there are no Flight Director cross bars displayed. This is normal because on the ground they are not required. You will see later that during the take off the Flight Director command bars will automatically appear. You will see more on Flight Directors in the Autoflight modules. EFIS MENU Normal Operation 20/20 If the aircraft is being completely shutdown, the EFIS displays are turned off using the appropriate brightness controls.
