This page is selectable from the Navigation/Communications tab suite and allows you to simulate radio communication between the ground and the flight crew.
| SELCAL | The display in each of the buttons (VHF L, VHF C, VHF R, HF L, HF R) indicates the currently tuned frequency of each of the radio receivers. |
| Mech Call | The display above the button indicates the station called from the flight deck. No display when there is no transmission. Selecting this button when station displayed above allows you to respond to a call from the flight deck. Selecting this button when no station displayed initiates a call from the ground crew to the flight deck. Chimes continue to sound until call acknowledged by flight crew, or self-cancel after 30 seconds. |
| Capt Obs F/O |
Allow you to communicate directly with the flight crew. Once selected, the boomset of the associated crew member is connected to your boomset in a separate audio system, allowing direct communication between you and the crew member. You do not need to use the mic PTT as a hot mic system is active. While private interphone is active, other crew members can receive and transmit as normal. |
| Ground Call | Allows you to simulate a call from the ground crew. |
| Attendant Call | Allows you to simulate a call from one of the attendant stations. |
| Attendant Location | Selecting this button displays a pop-up menu to allow you to select the attendant location. When station is displayed in button, select the equivalent station to respond to the call from the flight deck. When no station is displayed, selecting an attendant location initiates a call from the ground crew to the flight deck. Chimes continue to sound until call acknowledged by flight crew, or self-cancel after 30 seconds. |
| Satcom Voice Priority | Allows you to see the priority (Emergency/Safety/Non-Safety/Public) of the satcom voice call |
| Service Interphone | Switches flight interphone comms from the instructors station to 'service interphone' mode. The crew can only communicate with the instructor using flight interphone if the overhead panel service interphone switch is selected on. Normal crew flight interphone operation is unaffected. |
| Comm Noise | Allows you to set a level of noise interference on the communications channels. |
| RT Chatter | Starts/stops radio chatter transmission. Chatter stops automatically when the instructor or flight crew transmit, and resumes two seconds after the end of the transmission. |
| Real/Training Override | Allows you to select either TRAINING or REAL WORLD modes |
