Self-Check 1-Communication

Question 1

Function of DFDR?
How is the CVR erased?
How to operate VHF1 receive & trans and monitor VHF 2?
Function of VHF1 Emerg button
Function of BKUP VHF button?
Funtion of ATC DTLK button?

Answer 1

Digital Flt Data Recorder-records any event for later use
by maintenance

plane on ground-door open-select CVR on panel-press ERS until tone heard on headset

brings up bkup vhf on radio 1/5

press VHF-1 MIC & VHF-2 audio switch

tunes to 121.5 regardless of current selected freq.

BKUP VHF button displays back up vhf in 1/6 radio window and cursor is placed on corresponding field

brings up ATC DTLK window on PDU

ATC-DTLK- data link-display this on “on side” PDU

Question 2

INSTRUMENTS

6. What is the function of the Cursor Control Device(CCD)?
7. What is the function of the CCD trackball?
8. What is the function of the CCD data knob?
9. What is the function of the CCD display switch?
10. How is Display Unit reversion achieved?

Answer 2

CCD is pilots primary interface with all display units.

Trackball drives the cursor on displays from one to another.

Data Set Knob another way to change info highlighted by cursor

Display Switch rapidly moves cursor through displays

Display Unit can be reverted by turning dimming knob to OFF position

Question 3

Instruments

1. Difference between Flight Path Symbo(FPS) & Pitch Symbol (PS)?
2. What is the function of the Acceleration Chevron?
3. What is the function of the Trend Vector?
4. What is the function of the Thrust Director?
5. What is the function of the Rotation Symbol?

Answer 3

Instruments
FP symbol shows the actual vertical trajectory of the aircraft
Pitch Symbol displays aircraft pitch angle

Referenced to the FPS, the AC gives instant indication of acceleration or deceleration along the aircrafts flight path and immediat indication of doable path angle at current thrust setting

Trend Vector (TV) give an indication of increase or decrease in speed, relative to the ASI pointer
    Above pointer speed increasing, below it is decreasing

Thrust Director is the box in which the AC must be placed to fly pre-selected speed on the panel

The Rotation Symbol(RS) provides pilots with easy to follow guidance to control rotation on TO

Question 4

INSTRUMENTS

Answer 4

6. The CCDis the pilots primary interface “finger over display units.
7. Trackball drives the CCD in it’s journey around the glass screens
8. Data set knob is another controller for input on PDUs. POFs and certain boxes in pre-flight settings
9. Display Switch. Switches display units from one display to another
10. A Display Unit
