Paco is correct in that the Gazelle entry to auto at low level and IPS (intermediate pitch setting, 13.5 degrees at about 125 kts) was to zoom climb leading with cyclic and retaining sufficient collective to maintain Nr. The manoeuvre would give 2 to 300 feet extra altitude before a gentle nose over selected the 60 kts auto speed. The extra height gained meant that instead of the field ahead, you had more options in selecting your field and turning into wind.
