@@inflight_aviation can each airline order specific thrust settings? As far as I was aware, all -700’s came fitted with the CFM56-7B24, which could provide a 26k bump takeoff when needed. If airlines can change that, then there’s something new I didn’t know!
@@tyredcar03 yup! So all the -700 operators that I know of have a fixed max derate of 24K thrust. I’ve heard Alaska can bump theirs to 26K only if sent through ACARS, so it’s not selectable and only happens once in a blue moon. Southwest has 737-700s fixed to 24K and all takeoffs are performed with 24K thrust with an assumed temperature (if available). Southwest doesn’t allow fixed derates, (22K or 20K) so it’s either an assumed temp or full 24K. The -800s have 27K bump available if sent through dispatch and rarely happens, usually the max power is a 26K with bleeds off. And out of SNA Southwest is the last remaining airline to do the full noise abatement procedure still, with max power (24K on the -700 and 27K on the -800) and the -700s use flaps 10 and the -800s use flaps 25. Also just for your knowledge, United’s 737-824SFPs have 27K bump available only if sent by dispatcher, same for Delta and American on the -800s, and on Alaska it is selectable anytime. Cheers!
@@inflight_aviation wow, that’s great info! My knowledge on that comes mostly thru flight sim. While the addon I use is pretty in depth, it doesn’t model any of that so I had no clue. Thanks so much for the info!
This is AWESOME! Just one thing- it seems like full 24K. I don't think Southwest has 26K Bump on the -700, but if they do thats so awesome!

@@tyredcar03 gotcha, yeah the MSFS 737s all have the bump option so that makes sense!
@inflight_aviation to be fair I fly the PMDG add-on, but still same story 😂
Very interesting!
Liked and subbed ;)
