In the report, Appendix H, para 15.c.(3) states: "These tests indicated that the height loss from apex during the accident manoeuvre was not affected significantly by power setting". Therefore, whatever the thrust was past the apex the outcome of the pull through would not have been significantly affected. Similarly, the thrust at the apex would not have affected the pilot's ability to perform an escape manoeuvre. However, the low thrust on the pull up was significant in that it was a contributory factor to the low apex height and low apex airspeed achieved.
