I don’t leave CR for another 85 days and this made me a bit sad because it brought back every other time I have left Costa Rica. On the flip side, each time I have arrived here I have felt like I was coming home. Great video. It’s nice that you shot such a long one. I’m using headphones so it’s like I’m in the damn plane. 😎

That is one smooth take off :-) And I like how quiet the take off was

@inflight_aviation 10 ай бұрын

Oh yeah, it was totally silent because of the 27K Bump thrust activated, it got louder once the thrust was reduced to climb.

@pilerks1 10 ай бұрын

I have never seen 737 hold max thrust for this long, nor at this high of power. Even when departing dca or sna, which I have posted many times. Thrust was not reduced until maybe 5k feet? Excellent capture.

Yes, it was a 6700 foot ASL reduction, and the bump thrust, crazy right?! Thank you very much for your compliment and for watching!

@@inflight_aviation what's "bump thrust"? Great video! Thanks!

@inflight_aviation 9 ай бұрын

@@joelt4416 so in this case we were flying with CFM56-7B engines. Those are rated for 27,300 pounds of thrust, but the airline usually uses up to 26K. At certain airports like SNA, BUR, SXM, DCA, PHX, RNO, DEN, and SJO, the pilots break the derate and can select an option on the flight computer which “bumps the thrust” to provide full thrust of the engines. In this case, the pilots used this bump thrust. Not all aircraft and not all airlines have it available. American has the option on some 737s and some A321s. It is only used for high elevation, hot air, low pressure, and a very heavy plane where it is unsafe to takeoff with a 26K power. Thanks for your comment and for watching!

It sounded like thrust was asymmetrical almost

@SSAviation737 Ай бұрын

Nice video. N1s in the description are little off. Maximum allowable N1 is 104% anyway and this was in the 101% range. Still 100% 27K thrust though and the maximum available thrust for these conditions.

Thanks! So this information was given to me by the flight crew once we got to DFW, therefore I’m sure it’s very accurate and this definitely sounds about right. We redlined the engines at the end- it was crazy awesome. Thanks so much for watching!

@@inflight_aviation Ohhhh...that's unique. Maybe 104.3% N1 was set in the computer but the autothrottle was being wonky and commanded it to the 102-ish range. 104.3 would be above the maximum allowable N1 though.

@inflight_aviation 14 күн бұрын

@SSAviation737 yep 104.3 is above max allowable. If this flight was 2 months ago I’d have way more info for you, I’m sorry that’s all I have. I have a couple flights in the near future destined to use the bump and I’ll get a ton of info then!
