Crab is 100% correct:
In my experience, the zoom climb from low level, 180 EoLs in the Gazelle were only ever achieveable as a pre-briefed exercise and in the real case would be very unlikely to work given a normal delay for recognition of the failure and the subsequent reaction.
In reality we weren't often exactly 180' downwind when blatting about max chat at 50ft.
So the zoom climb auto, even if a bit delayed by reaction, would give you the slim chance of a. getting the speed off and b. turning 40 or 50 degrees and landing into wind.
If possible choice of fast low level transit in Germany was over trees, at tree top height, about 100-200m inside the tree line. (There were a lot of forests in our area of interest. ) A zoom auto (in theory) would get you to the surrounding countryside!
