The Comms page is more for the company monitoring purpose. I enter the crew duty start times, flight time and number of sectors we are operating that day. I then enter the cockpit crew ID
numbers, and who is doing the takeoff and landing. I also pre-enter all the data to request for take-off data information, like the temperature, QNH, runway code and condition, windspeed and also any MEL
items which may affect our takeoff performace.
That is the basic set-up. At this point I start the flow pattern of the cockpit, making sure that the switches are all in the correct position. The PNF should at this point also have come back from the walkaround, and start going through the FMC and Comms page as I described.
When we are both done, we go an instrument check, checking tha altimiters and compass headings, before doing the Before Start Checklist. After this, we get a loadsheet, and get out fuel form from the refueller, which we check and sign. We run through the loadsheet checking it is all correct then enter the ZFW and TOW into the FMC, before punching in the takeoff data and V-speeds.
