Hi,
It would be lovely if take-off performace calculations based on D-TO1 and D-TO2 for some aircraft, specifically 747-400, could have variations in de-rated values. Some engine models have TO1=8% reduction in total thrust and TO2=20%, while some others have -5% and -15% respectively. Now that we have a total thrust value and flat rate temperatures in airframe performance section of SimBrief Airframes, it would be great to have this feature.
Thanks,
You can already select TO, TO1 or TO2 (or leave it on automatic), and enable/disable D-TO via the “Flex Temperature” drop-down:
Regards,
Tim
I believe my request was misunderstood. What I meant was a feature to specify the amount of de-rate for each aircraft profile, as SimBrief currently does not allow different types of engine models for the 747-400. The common de-rated thrust redcutions from full take-off thurst are TO1/TO2 of -5%/-15%, -8%/-20%, and -10%/-20%, obviously depending on the engine type.
