I find it strange that the 737-500 has winglets yet no 737-600 have any, is there any reason for this?

cheers!!

Thanks camiloa380, the discussion still does not state a good argument for not installing them.

Who is going to pay for certification? And how many planes will that be spread across?

Sounds like from the discussion that west jet is in the process of certification.

Westjet will NOT be getting winglets on their 736s. They determined awhile ago (don't know when exactly), that the costs would outweigh the benefits.

This is an interesting question.. could it have something to do with the nature of the -600's operational use as a short-haul aircraft and the related economics? I recall Winglets costing in the range of $3-4M USD per aircraft to install.. perhaps the payoff is more pronounced for aircraft that operate longer flights?

Perhaps someone with some economic [and perhaps technical] background on the subject can comment and clear it up.

I've often wondered what a BBJ based on the -600 with "wet" belly tanks and winglets performance would be like. I know that would eliminate virtually all cargo volume in the belly, but the thing would be more than big enough to store the bags somewhere in the cabin.

And for that matter the -600 is kind of an odd duck anyways. There's what, 70 of them in service?

I expect the main reason was covered in the earlier thread. With only 69 737-600s built, the certification costs would probably be too high on a per-aircraft basis.

And they're not only used on shorthaul routes. WestJet often uses their 13 737-600s on nonstops of 4 or 5 hours, like the YUL-YVR nonstop below with a scheduled time of 5 hrs 34 min.

Look at the list of 737-600 operators:

SAS (28)
Westjet (13)
Tunisair (7)
Malev (6)
"Janet" (6, soon)
Air Algérie (5)
Austrian (2)
Eastar (1)
Midwest (Egypt) (1)

Of that list, I see only Westjet and Austrian as even somewhat likely to bite on the capital cost of winglets.

15 frames is not going to cover the cost of the program.

The -900 (non-ER) was produced in similar numbers, but had operators more likely to commit to winglets.

Where did the Janet airframes come from? I presume they had previosu owners.

That is, of course, presupposing that Janet actually exists

Most of the stage lengths on the routes the 736's run don't justify the need for the winglets. It would have been cool to see the babyNG with winglets, but that isnt going to happen.

Ever flown in one? You can feel a slight difference in G's on takeoff compared to her larger brethren!

Not me....and I don't think I'll ever get the chance in this lifetime, if ever.

My theory of why the lack of winglets on the 736 is mainly because the amount of the airframes produced does not justify the costs of developing them for the type. That is my only opinion.

Ill be flying a Westjet -700 & -600 this weekend (look for my first trip report to follow  ). It will be my first time on the -600 so ill see if I can spot the difference in G's. I wish Westjet followed through with the plans for winglets on 737-600's as it would be neat to see the -600 with winglets.. If I recall right didn't WS incur some sort of penalty for cancelling the plans?

Looks just like a -700 with winglets.

Doesn't take too much to figure where the inspiration was... and although basic, it still looks good on the 736's!

A couple of questions:

1) What kind of engineering would need to be done to develop winglets for the 737-600 that wouldn't already have been done for the rest of the 737 NG fleet?

2) What kind of certification process would be required for this kind of a mod? What, exactly, would they be testing?
