Qantas To Boost Fuel Efficiency With Split Scimitar Boeing 737 Wingtips
Вставка
- Опубліковано 5 вер 2024
- Australian flag carrier Qantas is making changes to some of its Boeing 737-800s, updating more than a quarter of the fleet with split scimitar winglets. The winglet is an advancement from the blended winglet design that was introduced after the launch of the 737 Next Generation family. While both designs are said to reduce air drag and make aircraft quieter, split scimitars reportedly boost efficiency by as much as two percent.

For those who might say "It'll be difficult to distinguish this from 737 Max planes", look at the engines. That'll be enough to tell them apart from the new design because these split scimitars look amazing on these NGs.
It's not the Max I'm worried about.
It's Boeing.
even the wingtips are slightly slimmer than the MAX wingtips which look cohesive and substantially bigger than these. Also there are no chevrons in these engines compared to the max
You can also distinguish 737 Max planes by their ability to nose dive really fast, and their new, fuel efficient open hull design.
@@nasseralkhelaifi1853I woder if there is still parts of the ET302 wreckage at Addis Ababa
Yep The AT winglets on the MAX does look different when you look closely.
Thank you for not having any unnecessary terrible music in the background. Great content!
2% fuel saving is huge
yes, but the flight duration has to be long enough to offset the added weight costs.
it saves billions of dollars bro
They actually look more modern than the winglets installed on the max.
It’s newer than the MAX winglets.
Guess they plan on retaining the 800's longer then expected, to recoup the expense of the winglets.
@@bringbackmd7579 the 23 aircraft they are installing them on are the youngest in the fleet. The first aircraft to get them installed was delivered in 2011.
They had 737 batches delivered in 2002-2006, 2008, 2011-2014 and 2017-2018.
They have 20 A321XLRs due for delivery starting mid next year and another 94 options. Once they start arriving, they'll retire the oldest 737s. It will be another 8-10 years before they start retiring the 23 aircraft getting the new winglets.
I disagree
@@sussy001it’s not newer than the max. these wingtips have been in use around 2013
It would be fascinating to know the expected RIO based on the retrofit costs
Wrong! These tips were introduced so that flight-reviewers had something to talk about in the cruise phase.
The MD-11 actually had these split simitar type winglets before the 737.
Nothing about the environment... if it saved one percent on fuel consumption then it would pay for itself very quickly
That's how the whole concept of "eco"should really works.
I agree... better to upgrade current aircraft than replacing these with the killer airplanes.
Hasn’t Qantas purchased A320neo’s and A220 to replace it’s 737 fleet? If that is the case then why retrofit the 737s if they are not supposed to be around for much longer?
Yes agreed I am wondering with new aircraft coming on line - Is this financially responsible
The aircraft they are retrofitting arrived from 2011. The newest batch of 737s arrived in 2017-2018. They have another 8-10 years left before these aircraft will be retired.
The oldest 737s arrived in 2002.
The A220s are replacing the 717s. The A320s start arriving in the 2nd half of next year.
@@magical_catgirl agreed, it will take time to replace even the older 737 NG fleet with the A321. I really want to try the new A220!
@@theharper1They’re also specifically replacing them with the XLR, which hasn’t been approved yet. They planned to receive them late 2024 when they were ordered but that timeframe is looking very unlikely now. They’ll probably receive their first XLR by late 2025 and that’s really if everything goes smoothly which I find unlikely.
@@TheMergeBuff45 yeah, the A321LR order was for Jetstar (Qantas group not Qantas flag)
Why did they bother themselves with it, aren`t they going to be gradually phasing out the boeings shortly.
Clearly not.
2% only 🎉 guess it Adds up if yearly
Great insights!
great video
Jeju Air has already done this to some of their NGs since 2019...
lol who asked about the Jeju? United already started since 2013.
But why have these to be retrofitted, surely Boeing could have delivered them from the factory like this, especially if they contribute that much to fuel efficiency?!
These are not new planes. The one mentioned in the video - VH-VZU - was delivered in 2011, and the average age for Qantas 737s is 16 years. Those winglets were not available back then, so could not have been delivered new with the split winglets.

I like it
Spilt scimitar is nothing new. Never too late to install it.
Poor business decision made upon by qantas. boeing is failing airliner. qantas must to chose airbus, embrer, or comac
This is for their current 737s, they don’t have the MAX or have it on order.
Older Boeing jets are more better quality than the ones now that have door fly away 10 mins after takeoff
COMAC? Seriously?
Do you understand what’s happening at all lol
What the hell are you smoking?! Up until the max debacles, the 737 was the popular airliner on the planet. I thought Qantas was getting rid of all old aircraft but it’s a good decision if they plan on keeping the 737 NG’s awhile.
