Avionics

Question 1

On your clearance you were issued a cruise altitude of FL 470. During your climb you were issued an amendment of FL 430 as a final cruise altitude:

Question: What are some indications you did not reach your original cruise altitude of FL 430?

Answer 1

Answer: 1.CLB Mode never changed to CRZ,

2. VSD path is incorrect,
3. Auto Speeds are incorrect.

Question 2

Question: How could you correct this?

Answer 2

Answer: TSC / FMS / Perf INIT / Alt Spd

Question 3

Question: During taxi out you notice that on both PFDs there is an amber MAG2 displayed, what does this indicate and how can it be corrected?

Answer 3

Answer: Both pilots are using the same source Answer: POF / Flight Guidance / Sensors

Question 4

Question: At what altitude must the autopilot be disengaged?

Answer 4

Answer: 65 feet AGL – Flaps 39° Minimum Autopilot Disengage Height from an ILS or LPV Approach.

Answer: All other operations is 200 feet AGL.

Question 5

Question: Flying a short range (Green Data Approach) VOR approach. Is there any time I cannot use the approach button on the guidance panel?

Answer 5

Answer: Use of VOR Approach (VORAP) mode is prohibited if VOR station overflight is required during any portion of the intermediate or final approach segments, excluding the missed approach point.

Question 6

Question: Any limitations in reference to operating Airborne Weather Radar while on the ground?

Answer 6

1. Operation During Refueling:

Answer: Do NOT operate radar during refueling of the airplane or when within 50 ft. (15.3 meters) of other refueling operations.

2. Operation at Other Times:

Answer: Do NOT operate radar within 11 ft. (3.4 meters) of ground personnel.

Question 7

Question: How would you turn the Weather Radar ON while still on the ground?

Answer 7

Answer: TSC / WX & FLT Info / Ground Override

Question 8

Question: When must the Terrain Awareness be selected OFF?

Answer 8

Answer: The Terrain Inhibit (TSC / Inhibits) should be selected for airports not contained in the EPIC EGPWF database

Question 9

Question: Before you taxi out of the ramp you deploy the HUD combiner. How would you know that the HUD combiner is in the correct deployed position?

Answer 9

Answer: The absence of “Align HUD” displayed in the HUD.

Question 10

Question: When using EVS, when can “EVS Lights” alone allow you to descend below minimums?

Answer 10

Answer: Flight Director (FD) or Autopilot (AP) with vertical guidance is required.

Straight-in approaches to an MDA (Using FMS Vertical Path) or DA/DH are authorized.

At 100 feet HAT, visual cues must be seen without the aid of the EVS to continue descent to landing.

Question 11

Question: During an ILS approach below 1200 feet RA, both GREEN triangles on guidance panel above PFD SOURCE switch. What does this indicate?

Answer 11

Answer: Answer: During an ILS dual-couple approach, both the left and right arrows light up below 1200 feet (Radio Altimeter) to indicate the system is averaging data received from both NAV Receivers. If the dual-coupled mode is cancelled due to loss of the approach mode, the system automatically couples to the PFD that was selected prior to initiating the approach. BOTH navigation receivers’ data is being averaged.

Question 12

Question: Selecting “GPWS Inhibit” inhibits ALL GPWS aural warnings except?

Answer 12

Answer: Mode 7 Windshear

Question 13

Question: What is the Primary Heading source for the SFD?

Answer 13

Answer: AHRS + Magnetometer

Question 14

Question: Can you select another heading source?

Answer 14

Yes

Question 15

Question: How would you select another heading source for the SFD?

Answer 15

Answer: SFD, Press the “Menu”,

Select HDG Source,

Select another IRS.

Question 16

Question: What indication would you see if you select the same heading source as the onside PFD?

Answer 16

Answer: HDG + the IRS number would be amber on the PFD.

Question 17

Question: During the taxi out you notice that that pilots CCD is inoperative. Can you dispatch without the pilots CCD?

Answer 17

Answer: Yes, Both can be inoperative.

Question 18

Question: While looking in the HUD you notice a vertical line with a “1” “R” & “2” marked on it what is this?

Answer 18

Answer: V speed awareness band

Question 19

Question: When would you expect to see the V speed awareness band to appear?

Answer 19

Answer: After pressing the TOGA button and configure the aircraft for takeoff.

Question 20

Question: How do you know you have your seat in the correct position when you do the HUD test?

Answer 20

Answer: You see a “T” at the top of the HUD and a inverted “T” at the bottom.

Question 21

Question: What’s the source of HUD symbols?

Answer 21

Answer: HUD computer

Question 22

Question: What’s the source of the EVS image?

Answer 22

Answer: The EVS (IR) camera, unlike the HUD, uses infrared technology and is optimized to detect runway lighting.

Question 23

Question: Looking into the HUD, how can you tell if the EVS is selected ON and ready for use?

Answer 23

Answer: It indicates EVS A, H, or L in the upper left corner.

Question 24

Question: Looking into the HUD, you see a EVS “C” in the upper left corner. What does this indicate?

Answer 24

Answer: It is in the CLEAR mode.

Question 25

Question: How can you switch from EVS A to EVS C and vice versa?

Answer 25

Answer: Use the rocker switch on the pilot’s side stick

Question 26

Question: Describe the operation of the EVS WSHLD HT switch.

Answer 26

Answer: When selected, the switch light blooms cyan when pressed and the ICON on the nose of the aircraft turns Green and five (5) minutes of continuous heating is provided to the EVS windshield. Otherwise, operation is automatic if the aircraft is airborne.

Question 27

Question: You look into the HUD and the airspeed tapes and altitude tapes are not displayed. How do you get them back

Answer 27

Answer: Onside TSC, POF, Disp Ctrl, HUD/EVS, Symbology, Deselect Declutter

Question 28

Question: How many Air Data Systems (ADS’s) do we have?

Answer 28

4

Question 29

Question: What is NUC?

Answer 29

Answer: NUC stands for Non-Uniformity Correction. It’s a calibration process that results in a cleaner picture and occurs during camera power-up, flaps selected from 0° to 10°, or manual NUC selected.

Question 30

2000 ft agl

Question 33

Question: Using EVS A at what altitude does the Runway symbol appear in the HUD?

Answer 33

Answer: 350’ AGL the runway symbol appears. At 325’ AGL the airport symbol disappears and at 60’ AGL the runway symbol is removed.
