From ATSI:
Ref. SIDs, or Standard Departures as we call it, is pretty simple for OMAA. Runway heading climb 3,000 feet (after passing 500 ft contact APP 124,4). I know you still have to program your FMS, but the only changes should be track heading 127 or 307. Isn't that easy to change?
Simple SIDs make change easier yes.. This is a generic example of what happens assuming we're not interrupted by the people Mensaboy mentioned coming into the cockpit. Unfortunately never a simple process.
1) F/O reprograms the FMC selecting rwy and SID. He then compares the SID vs chart and makes sure the new SID connects with the rest of the route.
2) Capt checks what the f/o did.
3) A quick briefing follows where the new taxi route, and SID (and engine out procedure if there is one) are discussed, finished by setting the MCP (hdg, alt etc).
4) F/O recalculates t/o data for the change of rwy
5) Capt checks what the F/o did.
6) New thrust setting, flap setting, acceleration height and v speeds all entered into the FMC together.
7) Lastly, we look at each other and say 'What have we forgotten'
