4. How many HF frequencies can be stored by the TCP?

Data is stored in memory for the last 100 tuned frequencies

Up to three pages of stored HF frequencies (24 total) can be stored in the TCP

No stored HF frequencies pages are available in the TCP

Up to two pages of stored HF frequencies (16 total) can be stored in the TCP

The TCP can store up to three pages of stored HF frequencies, with a total of 24 frequencies. This means that the TCP has the capability to store a significant amount of data, allowing for the storage and retrieval of a wide range of HF frequencies.

5. How many transmitter selector switches on an Audio Control Panel (ACP) can be selected at any one time?

Normally, only one switch is selected at a time for each crew station

CAB and SAT may be selected at the same time for cabin to SATCOM conferencing

Normally, only one switch is selected at a time for each crew station, however CAB and SAT may be selected... Normally, only one switch is selected at a time for each crew station, however CAB and SAT may be selected at the same time for cabin to SATCOM conferencing

Pushing the CAB transmitter select switch twice within one second places a priority call to a selected cabin station

The correct answer states that normally only one switch is selected at a time for each crew station. However, in the case of cabin to SATCOM conferencing, both the CAB and SAT switches can be selected at the same time. This means that during cabin to SATCOM conferencing, two switches can be selected simultaneously. Additionally, it is mentioned that pushing the CAB transmitter select switch twice within one second places a priority call to a selected cabin station, indicating a specific functionality of the CAB switch.

Depressing and holding a VHF R radio tuning switch will cause the radio associated with that switch to perform a self-test, which causes the radio to break squelch until the button is released

Squelch function on the B787 is automatic

There is no squelch function on VHF R in the B787

The correct answer is to select TCP MENU, RADIO MISC page, VHF R squelch line select key. This means that in order to toggle the VHF R squelch on and off, the user needs to access the TCP MENU, navigate to the RADIO MISC page, and select the VHF R squelch line select key. This action will enable or disable the squelch function on the VHF R system.
