EFIS MENU PFD Presentation 1/97 EFIS MENU PFD Presentation 2/97 EFIS MENU PFD Presentation 3/97 EFIS MENU PFD Presentation 4/97 EFIS MENU PFD Presentation 5/97 EFIS MENU PFD Presentation 6/97 The Primary Flight display, PFD, displays all the normal Primary Flight indications. • Attitude, • Airspeed, • Altitude, • Vertical Speed, • Heading and Track. EFIS MENU PFD Presentation 7/97 Notice that the indicators are laid out in a classic instrument “T” configuration. EFIS MENU PFD Presentation 8/97 The PFD also displays other information. The upper part of the display is used to provide information to the pilots associated with the Flight Management and Guidance System (FMGS). The area is known as the Flight Mode Annunciator (FMA). You will learn more about the FMA in the Autoflight modules. EFIS MENU PFD Presentation 9/97 A Flight Director pb on the EFIS control panel enables the pilots to switch the Flight Director display on. Notice that there is an indication on the FMA when the Flight Directors are switched on. CAUTION: Both Flight Directors must be switched on or both off. You should never fly with only one Flight Director selected on. EFIS MENU PFD Presentation 10/97 When below 2500 feet a digital radio altimeter is displayed. In this module, we will concentrate on the Primary Flight indications. Let’s start with attitude! EFIS MENU PFD Presentation 11/97 Attitude information is shown at the center of the display. EFIS MENU PFD Presentation 12/97 The attitude indicator works in the normal sense. The aircraft is represented by 3 black and yellow symbols which remain fixed. EFIS MENU PFD Presentation 13/97 There is a graduated scale for pitch angle above and below the horizon. EFIS MENU PFD Presentation 14/97 Bank angle is displayed at the top of the indicator, each graduation represents 10 degrees angle of bank. EFIS MENU PFD Presentation 15/97 The Roll Index triangle moves against a fixed scale to show angle of bank. To show both the pitch and bank indications in use let’s look at the indication for a climbing turn. RRoollll IInnddeexx EFIS MENU PFD Presentation 16/97 In this example the aircraft is in a 20 degree banked turn to the left with a nose up pitch attitude of 10 degrees. 2200 ddeeggrreeeess ooff lleefftt bbaannkk 1100 ddeeggrreeeess ooffNNoossee uupp ppiittcchh EFIS MENU PFD Presentation 17/97 Below the roll index is the Side Slip Index. This index moves to indicate side slip and replaces the old fashioned slip ball. Side Slip Index EFIS MENU PFD Presentation 18/97 When the Flight Director pb on the EFIS control panel is selected Flight Director indications are superimposed onto the attitude indicator. In the example shown the flight director is centralized. EFIS MENU PFD Presentation 19/97 The vertical line is the Flight Director roll bar, while the horizontal line is the Pitch bar. Let’s look at an example of the Flight Director in use. FFlliigghhttDDiirreeccttoorrRRoollllBBaarr FFlliigghhttDDiirreeccttoorr PPiittcchh bbaarr EFIS MENU PFD Presentation 20/97 In this example the flight director is directing a pitch up and roll to the right. Once the aircraft has achieved the required pitch and bank the Flight Director bars will once again be centralized. Now let’s look at the airspeed indications on the PFD. RRoollll ttoo tthhee rriigghhtt ddiirreecctteedd PPiittcchh uupp ddiirreecctteedd EFIS MENU PFD Presentation 21/97 EFIS MENU PFD Presentation 22/97 The Speed scale moves behind a fixed yellow reference line and triangle. In the example shown the indicated airspeed is steady at 250 knots. EFIS MENU PFD Presentation 23/97 When the aircraft is accelerating, or decelerating a Speed Trend Arrow appears. This arrow shows the value that will be attained in 10 seconds if the acceleration remains constant. In the example shown the aircraft will decelerate to 240 knots in 10 seconds. The use of the speed trend arrow will be demonstrated during your simulator training. SSppeeeedd TTrreennddAArrrrooww EFIS MENU PFD Presentation 24/97 When the Flight Management and Guidance System, FMGS, is controlling the airspeed a magenta Target Airspeed triangle appears. This is normally referred to as the Managed speed. In the example shown the Managed target airspeed is 240 knots and the aircraft is decelerating towards that speed. Managed Target Airspeed EFIS MENU PFD Presentation 25/97 If the target airspeed is selected manually a blue triangle appears. This is normally referred to as Selected Speed. In the example shown a Selected airspeed of 260 knots has been set and the aircraft is accelerating towards it. Selected Target Airspeed EFIS MENU PFD Presentation 26/97 Selected Target Airspeed Manual speed selection is achieved by a rotary selector on the FCU panel. Just above the selector is the indication of the selected speed. Speed Selector and Indication EFIS MENU PFD Presentation 27/97 As a general rule on the PFD a Magenta indication means Managed and a Blue indication means selected. You will see this in the examples that follow. MMaaggeennttaa ==MMaannaaggeedd BBlluuee == SSeelleecctteedd EFIS MENU PFD Presentation 28/97 To look at the various other indications on the Airspeed scale we will run through a typical flight profile. We will assume a departure with the Flaps in position 3. You will learn about the various flap and slat configurations in the Flight Control modules. EFIS MENU PFD Presentation 29/97 During the take off roll a blue decision speed, V1, and a magenta V2 speed are shown. Notice that since these speeds are beyond the visible scale they are shown as numbers.

Having thoroughly studied the Airspeed indications lets look at Altitude indications. EFIS MENU PFD Presentation 52/97 All the indications associated with Altitude are located on the right hand side of the PFD. CLB NAV EFIS MENU PFD Presentation 53/97 The main part of the display is dedicated to the Altimeter. To the far right is the Vertical Speed display. We will look at the altimeter indications first.

The gray scale moves against a fixed yellow line which represents the centerline of the aircraft. In the example shown the aircraft is heading 091 degrees. HEADING 091 EFIS MENU PFD Presentation 79/97 The small green diamond represents the aircraft track, and it is normally referred to as the TRACK DIAMOND. In the example shown the track is 094 degrees which means that the aircraft has 3 degrees of drift to the right. TRACK 094 EFIS MENU PFD Presentation 80/97 A selected heading may appear either as; • a blue figure, on the appropriate side on the compass scale or • a blue triangle EFIS MENU PFD Presentation 81/97 On the FCU there is a Heading selector, with an indicator, that is linked to the selected heading indication on the PFD compass. Target Heading Selector and Indicator EFIS MENU PFD Presentation 82/97 There is a direct relationship between the small white ticks on the horizon line of the attitude indicator and the compass scale. As the heading changes the ticks move to stay in line. Now let’s look at how ILS information is displayed and in particular concentrate on the compass scale. EFIS MENU PFD Presentation 83/97 The ILS pb on the EFIS control panel enables the pilots to switch on an ILS display. EFIS MENU PFD Presentation 84/97 The ILS display includes indications for: • Localizer, • Front course, • Glide slope, • Information. EFIS MENU PFD Presentation 85/97 ILS deviation information is displayed in the form of Localizer and Glideslope deviation scales. The ILS front course will be displayed in magenta at the side of the compass scale if the figure is outside the visible scale. EFIS MENU PFD Presentation 86/97 A magenta diamond represents the localizer. When the ILS front course is within the compass scale it is displayed as a magenta dagger. EFIS MENU PFD Presentation 87/97 In the example shown the aircraft is established on the localizer and the Glideslope indication has appeared in the form of a magenta diamond. EFIS MENU PFD Presentation 88/97 The aircraft is now fully established on the ILS approach. Let’s look at the indications on the compass scale in detail. EFIS MENU PFD Presentation 89/97 With the aircraft established on the localizer; • the heading is 230 degrees • the track diamond is showing 3 degrees of left drift • the ILS front course dagger is beneath the track diamond. You will see how useful the track diamond can be to help you fly an accurate approach in the simulator phase. EFIS MENU PFD Presentation 90/97 You will be given more information on the ILS system, the Flight Director, the radio altimeter, and the Flight Mode Annunciator indications later in the course. Now let’s look at another useful indication available on the PFD, the Flight Path Vector. EFIS MENU PFD Presentation 91/97 EFIS MENU PFD Presentation 92/97 The Flight Path Vector can be displayed on the PFD to show you what the aircraft is doing in relation to the world. It is an indication of the aircraft flight path. It is not a director. The green symbol, sometimes called “The Bird”, represents the aircraft. The attitude indicator represents the world. Let’s look the FPV in a bit more detail. To begin with we will look at the indication for an aircraft in level flight with no drift. For training purposes we will exaggerate the angles. EFIS MENU PFD Presentation 93/97 The aircraft heading and track are the same so the FPV and the track diamond are in line with the heading marker. These indications mean that the aircraft is not drifting. EFIS MENU PFD Presentation 94/97 The aircraft is flying level with a pitch attitude of 9 degrees. The FPV is on the horizon line so at present the flight path angle is zero, i.e. the aircraft is in level flight. Now let’s enter a descent and see what happens to the FPV. PPiittcchhAAttttiittuuddee EFIS MENU PFD Presentation 95/97 The FPV will move down to indicate the angle at which the aircraft is descending through the air. This is known as the Flight Path Angle. Now lets introduce some drift to the left. PPiittcchhAAttttiittuuddee FFlliigghhttPPaatthhAAnnggllee EFIS MENU PFD Presentation 96/97 As a result of wind from the right the aircraft is drifting to the left.
