GROUND LESSONS Exercise 5.2: Practice (Optional) Using the G1000 PC-based Simulator, power up the system. 1. Verify the Jeppesen database effective dates and note those dates in the space provided below. 2. Enter the transponder code "3470" and set the transponder to "ALT" mode. 3. In COM 1, enter 124.30 MHz as the active frequency and 133.00 MHz as the standby frequency. 4. In COM 2, enter 135.325 MHz as the active frequency and 118.90 MHz as the standby frequency. Exercise 5.3: Audio Panel Operation 1. Which key should be used on the audio panel (GMA 1347) to monitor a COM radio frequency without using it to transmit on? The COM key for the selected radio (COM1 or COM2) 2. Describe how the split COM feature works and provide a sample scenario of its use. Split COM allows the pilot to use COM1 while the copilot uses COM2. This proves very helpful for talking to an FSS en route without leaving the ARTCC frequency. Pressing the COM 1/2 key on the audio panel turns on Split COM mode. 3. Describe the function of the digital clearance recorder. Records the last 2.5 minutes of communication Pressing the PLAY key once plays back the latest recorded block, then returns to normal operation. Pressing the PLAY key during playback of a block halts the playback of this block, plays back the preceding block, then returns to normal operation (this permits cycling through the stored blocks to reach the desired block). Pressing the MKR/MUTE key during playback halts the playback and returns to normal operation. 4. What purpose does the red button located at the bottom of the audio panel (GMA 1347) serve? Forces display backup mode 5. When the PILOT ICS key is pressed, can the other passengers in the aircraft communicate with each other via the intercom? Yes, but the pilot cannot hear passenger intercom communications. 6. Does the COM MIC key selection have any impact on the display of the COM frequencies on the PFD or MFD? Explain. The selected COM MIC key causes the selected frequency to be green. Note that COM1 and COM2 frequencies in the COM Frequency window can only be green simultaneously when in Split COM mode (i.e., when COM 1/2, COM1 MIC and COM2 MIC are annunciated on the audio panel). 7. Two pilots are flying a long cross-country flight and encounters bad weather. The pilot flying the plane wants to get a weather update, but is struggling to get on frequency and be heard because the ARTCC frequency is very busy handling multiple reroutes. What tools are available to get the necessary weather information to continue the flight? A Stormscope or datalink weather may be available, although the most useful tool is the other pilot. By using the split com frequency, (the PIC) the ARTCC frequency can be monitored on COM1 while the other pilot can contact Flightwatch or the Flight Service station on COM2. 190-00368-04 Rev.
