Difference in 737 Scimitar winglets
Posted by Beneficial-Lake3212@reddit | flying | View on Reddit | 21 comments
First time poster, but a recent FO I flew with said there were two different types, and I hadn’t seen it before. I’m really good with aircraft ID, but this one was new to me. With this picture, I’d assume the right was a MAX and the left was a NG. Anyone know if that is the case or if the different styles aren’t necessarily indicative of aircraft type.

That is a split scimitar winglet on an NG on the right and an advanced technology AT winglet on a max on the left. The patents on some of the old winglets ran out and you are starting to see airbus 320’s with better winglets. The NG split scimitar winglet saves about 1-1.5% fuel burn while the max AT is in the 2-2.5% vs a classic. On longer range aircraft that are at cruise for 9 hrs plus it makes more sense for a raked wing tip vs an aggressive winglet. The winglet has a sweet spot of 1000-3000 miles where it pays off but shorter and longer you start eating into the benefits.

To my knowledge the raked wingtips are better but only if you have the option for the higher wing span. Aircraft like the 737 and A320 are limited by the wing span because of the airport parking position size. Then the winglet is the better option.

Also, some NGs don’t have the downward angled part of the winglet. Depends on the airline.

Yep, my airline has a bunch of -700s with no scimitar

Sounds like a fellow cowboy pilot

The scimitar isn't the part on the bottom. The scimitar is the part that looks like a scimitar. Some 757s have single scimitars.

AA has the original AP winglets still on their -800s.

Scimitar refers to the taper/rake on the tips of the winglets -- the NG on the right has scimitars, the MAX on the left just has split winglets.

can you pilots tell the difference in flight? expand if so, thank you
RaidenMonster@reddit
Flight, max is quiet.
On the ground, max takes a long time to start in comparison.
The old -700’s are my favorite to fly. I think the max7 will be awesome…if it ever comes out.

The MAX’s are more quiet and feel more “refined” to fly
The NG’s feel like flying a pickup truck

The wing for the Max is optimized for cruised flight. The faster you the Max, the more fuel efficient it becomes. This is also why the Max sucks ass in the climb.
It reminds me of the 747-8F where faster = more fuel efficient.

They’re quite disscimitar …
Swimming_Way_7372@reddit
There is nothing scimitar about the winglet on the max.

one is a max and one is an ng

Oh wow, I know this doesn't answer your question but TIL. I imagine you assumptions are probably correct.
barcode-username@reddit
Yeah it's the other way around, the MAX is on the left, NG on the right.
Yesthisisme50@reddit
Left is MAX
No-Version-1924@reddit
It's the other way around, the left one is the MAX and the right one is the NG.
The MAX doesn't use split scimitar winglets, but rather something called MAX Advanced Technology winglets.

Left is a Max, right is NG.
