Which are the four separate input channels for the Cockpit Voice Recorder?

• Channel 1: Cockpit Area Microphone (CAM) signals Channel 2: Flight Engineer headset signals Channel 3: First Officer headset signals Channel 4: Purser headset signals

• Channel 1: Flight Engineer headset signals Channel 2: First Officer headset signals Channel 3: Captain headset signals Channel 4: Cockpit Area Microphone (CAM) signals

• Channel 1: ACARS signals Channel 2: Captain headset signals Channel 3: First Officer headset signals Channel 4: Cockpit Area Microphone (CAM) signals

What is the most likely problem if flight crew reports loud Morse Code signal in their headphone?

• Failed to select the correct frequencies.

• Failed to engage Isolation Amplifier.

• Failed to engage "VOICE" or "VOICE ONLY" switch.

What does the term "image frequency" mean?

• Image frequency is the unwanted reception frequency two times the IF higher than the nominal frequency.

• Image frequency is the frequency of the local oscillator same as the nominal frequency.

• Image frequency is the frequency of the demodulator two times the IF higher than the nominal frequency

What is the purpose of the squelch circuit?

• It controls the receiver gain.

• It controls the receiver oscillator frequency for automatic tuning.

• It prevents amplified receiver generated noise signals at the speaker when there is no input signal.

Which statement is correct about the Selective Calling (SELCAL) system?

• 
  SELCAL is a call system that is part of the flight interphone system.

• SELCAL provides the crew with visual and aural warnings from ground stations which are equipped with a coding device.

• The SELCAL signal is transmitted and received on a RF-frequency of 75 MHz.

For transmission at frequencies of more than 30 MHz, what is true for "Skip Zone"?

• Only the sky wave is received.

• Neither the ground wave nor the sky wave is received.

• 
  It is the zone above the ground station.

What does "manual VHF Omni-Range (VOR)" mean?

• The deviation information to/from a manually Pre-Selected Course (PSC) is indicated on VOR

• The deviation information to/from a manually Pre-Selected Course (PSC) is indicated on HSI

  
  

• The combination of heading (HDG) and VOR bearing (QDM) is manually done, to find the relative bearing (RB).

What is the meaning of "Automatic VOR"?

• The VOR frequency is tuned automatically.

• In the "Automatic VOR" mode, the Pre-Selected Course (PSC) is selected automatically.

• The QDM information is automatically indicated on the VOR/RMI.

Which instruments and systems belong to the "Automatic VOR" indication group?

• VOR / RMI

• ADI and HSI

• VOR / RMI and HSI

If an aircraft is on a VOR radial 316^o heading 270^o, and a course selected of 150^o, what will be the indication of the HSI?

• TO indication, "RIGHT" deviation bar deflection

• TO indication, "LEFT" deviation bar deflection

• FROM indication, "RIGHT" deviation bar deflection
