Flex
Thank you, Old Smokey, for quite a nice explanation. No doubts on the Derated Thrust.
I do, however, have another doubt. Here goes:
If FLEX is still a reduced set of thrust, why can you select Max. Thrust with FLEX but you can't with D-TO? Is it because Vmc speeds with FLEX are not calculated to the respective thrust reduction, but to TO/GA thrust?
BTW, some "trick" that I've learned in a few sims I've witnessed is that on the 3rd segment you are supposed to select MCT, but if you decide, you can continue on TO/GA up until the time limit is almost up, whether it is 5 or 10 mins; that way you can get a bit more of thrust in those moments you need the most. Is it good practice to do the above? Recommended or not?
Thanks in advance
