Question(s) from a prospective S/O:
How is the timeline of an S/O during a flight? By this I mean, where does the S/O sit during T/O & Ldg, when does the S/O assume the cruise duties (duration into flight) and how long does the S/O remain at the station before vacating?
SO sits in the jump seat for TO and landing, SO gets in the seat at the discretion of the commander ie. he decides how the rest periods will be broken up. Whatever happens the captain / FO will sit in the seats until top of climb.
Who does the S/O sit with (Capt, FO, alone?) What seat does the S/O sit in?
So sits with Capt or relief qualified FO (assumes duties of captain while the captain rests.)
I heard a rumour a CX longhaul flight has 2 SO?
Haven't heard of this?
Is the S/O responsible for many pre/post flight duties?
No. SO usually does the cockpit safety checks, sometimes sets up the FMS at the discretion of the captain /FO.
