3. To ensure that this is so, the collective lever must be raised until the Nr droops. This will bring the remaining engine up to maximum power. If the remaining engine is NOT at maximum power then the performance promised in the RFM cannot be guaranteed.
Not true, collective has to be kept at the same position of a standard AEO maneuvre unless a droop is necessary to achieve transational lift to accelerate to Vtoss
Humm...
" SINGLE ENGINE FAILURE, RECOGNIZED AT/AFTER TDP (CONTINUED TAKE OFF)"
1. [...].Mantain 0º while using collective to droop NR to minimum of 90% and set 2.5min. power.

Yes, "quite clear"

Anyway... if you are taking off at any Tq. above 80% I don't think you need to use collective, the "droop" will be automatic. If you are very light you may need to use collective to drop NR and use all the power the engine can give (if you need it).

Geoffersincornwall, how is it in the sim at MGW ? I'd like to go there some day.


EDIT: I think the rotor is more efficient at NR 90% than 100% at 2.5min power , in the transition to Vtoss. No?
