For all the big Boeings,as you have no time to go for a checklist if you hoover up Jonathan Livingstone and his cousins at 2,500' on take off,.ex Dubai,Maldives,Seychelles,Nosy Be,etc..
OPO U30 BFA,.....basically,everything covered by the ditching checklist,below 5000'
O override on Gear n Terrain(least useful item but kills the warning)
P packs off
O outflow valves closed(very good idea,this one)
U undercarriage up
30 Flap 30
B Through in a "Brace Brace"..............now the lucky bit,,and once in the water
F fuel control switches to cutoff
A Apu switch,pull
Throw in the perfect manoeuvre to parallel the swell therebye avoiding smacking in to a crest,and..hey presto,there you have it,the perfect ditching...
IN YOUR DREAMS!
