Hi FE Hoppy,
I was on the L1011 for 15 years but never knew about auto take off.
We could take off in 75m vis using ILS & PVD (para visual display) but couldn't even engage the FDs until AA (min 1,000 feet).
We could use Control Wheel Steering (CWS) for take off - but we never used it.
Which system did you have?
