On the L1011s I flew, the Frisbee fairing was fitted to the -200 & -500 but not the -1 (known as the 'minus one' due the less powerful -22B engine variant).
It's a while since I flew them but seem to recollect that the -500 had a two stage Go Around power application for #2 eng out GA. Due to the short moment arm stabiliser control of the pitch-up moment was marginal and one would shortly have the control column fully forward.
Lurvly big flight deck - beats the little B747 doghouse hands down
