Hi,
The 'Maneuvre d'urgence' contains a note that refers to the follow-up procedure 'Vol avec IAS douteuse/ADR Check' that is reproduced in BEA's Interim Report #1, Appendix 9. There you'll find for FL250 - 370, W>190t: 3.5°/90%N1.
PJ2 has explained that a pilot would not be expected to go to 5° at FL350 and M.82.
