Why no winglets on C-GHLK?

Sat Dec 31, 2016 4:51 pm

The entire 767 fleet of Air Canada Rouge has winglets, they have been either retrofited with them before being delivered to Rouge or simply came with them already installed. However I've noticed that C-GHLK has no winglets and that she has been with Rouge since May, I was wondering if there was a specific reason for this?

4 Rouge 767s do not have winglets.

I'd assume this is due AC's seemingly immediate need to put them into service.

With the cost of oil down the cost of adding winglets out weighs the return....

C-FJZK f/n 675, C-GHLA f/n 656, C-GHLK f/n 657, C-GEOQ f/n 647

With the exception of 675, which was not an Air Canada fleet member prior to entering service with Rouge, the other three spent approximately 2 months in Singapore being converted for Rouge, which is comparable to how long those took that were fitted with winglets.

Rouge is using a lot of 763s in winter on short runs. LAS, FLL, CUN, MBJ. Some of these routes have the 763 operating year round. Winglets aren't required and are actually dead weight on these short hops, as the increase in range or payload isn't necessary.
us Air Traffic Controllers have a good record, we haven't left one up there yet !!

I wouldn't say they're dead weight. Range/payload considerations aside the benefit is a drag issue, decreased fuel flow. The return on investment I am not sure however talking with an Austrian crew prior to any wingleted 767s at ACr, the results had impressed. Originally they were told of a 2% decrease in fuel but after flying them for sometime the results were about 3-4% better burn.

Of course the cost of gas, routes flown etc would dictate ROI but it certainly was well worth it.

Why all Rouge FINs have not received them I don't know. Perhaps it has something to do with leasing, heavy check timing, and how long those FINs are expected to stay.

If the weight of winglets on short segments were equivalent to "dead weight" you wouldn't see them on practically every regional jet produced in the past 10 years.

Aren't there some 767's of certain build vintage that are incapable of receiving the winglet modification for structural reasons ? I seem to recall that being the case with the BA example now with Open Skies.

RR engined 767s are not certified, from memory?

These planes often operate routes where winglets would be especially effective so I'm not sure why they haven't retrofitted them.

2 ears for spatial hearing, 2 eyes for depth perception, 2 ears for balance... How did Boeing think 1 sensor was good enough?!
