Thanks for your help with this folks.
So as for flaps: on the NG we normally take off flap 5, at 1500 ft climb thrust is set automatically, select clean speed, flap 1 as speed increses beyond v2+15, and flap up on the speed tape schedule.
Landing usually goes flap 1, flap 5, then gear down and flap 15, then flap 30 and set vref+5.
Go-around flap 15, at 1000' flap handle controls the speed until toga terminates, select flap 5, flap 1 then flap up on schedule.
Is it similar for the 777? I see there are different flap positions available.
cheers
