ok,
FCOM : Initial take off roll section p3.4 states' Light forward pressure is held' so YES somehow it is a standard procedure eventhough i dont see it as quite so necessary.I never used light forward pressure with dry runway ...as i believe my nose wheel is steering properly and well connected to the asphalt.
However if the runway is slippery, the light forward pressure below 80 kts will be useful in increasing the nose wheel steering effectiveness.
I do stand to be corrected as usual
IRRENEWAL..i didnt mean to write in my earlier post 'boeing states' but boeing statement....sorry i have a poor english too
