We only insist on the use of 102 during Cat A because that is what it says in the RFM. Nowhere does it say you can use it for OEI landings but you don't have to be a rocket scientist to speculate that a higher Nr might come in handy.
I might have miss-understood that but......
Having checked my CSE grade 3 in Rocket Science:
Surely maintaining a sub optimal NR (102%) will use more of our valuable OEI Tq available than maintaining the optimal NR (100%) for any given flight configuration? AEO we have spare Tq to store as Nr so no problem.
It also seems a little counter productive to suggest converting Tq into Nr so that we have spare Nr in case we run out of Tq?
I like to store my energy as airspeed, height and Tq, with NR as my weapon of last resort.
On this basis of the above I never use 102 for OEI.
Happy to be corrected by any holder of a CSE in Rocket Science (grade 2 or above)
