Dear Cheeky Monkey,
I quote from my companys Flying manual ('Landing Techniques' from the 'Normal Procedures') which states:
"Nosewheel steering will be improved with a forward pressure on the control column which increases weight on nose gear."
This is the technique I was taught and I apply it at all times.
WOK states, <If one was struggling with steering control it might help, but I don't think it is necessary or even desirable under normal circumstances.> I agree with WOK to a point, in that I don't believe it is always necessary. However I believe it is better to routinely apply light forward pressure on all landings rather than waiting until the day that you are struggling with steering control.
WOK also states, <If you stuff the stick forward too much you just run an increased risk of nosewheel shimmy if the torque links are a bit slack.> I'm not sure about this point, however shimmy is always a possibility if the torque links are slack. By the way I never 'stuff' the nose forward but apply light forward pressure in a controlled manner. (When I'm having a good day that is!)
Hope this is of help to you.
Regards
Exeng
