Did CO Recently Add Winglets To ERJ-145s?

I thought I saw a CO ERJ145 with winglets leaving GSO the other day.

Was it my imagination?


A good landing is one you can walk away from. A great landing is if the aircraft can be flown again.

Those are ERJ145XRs -- extended range; Continental Express is the sole operator of those. They also have two fairings at the rear of the plane and one in the center below the center fuel tank.

Just a FYI. those fairings are called strakes.

The XRs have been around for a long time. The winglets, strakes, and fuel tank fairings give 'em away. Great airplanes, by the way.

No it wasnt your immagination. CO express flies the 145XR (extended range) and as said before they are the sole operator of them. For some reason though, CO did not paint these winglets, however they are just grey. Hope this helped.

OK, Great! Thanks for the heads up!

I saw it, and then remembered another user confusing a ERJ-170 for a UA 733 with winglets and saying to myself, "Naa, that was just your imagination."

I was starting to wonder if winglets were becoming like body piercings, with little airplanes getting them just to fit in.  Smile

I can assure you that the winglets are painted white,grey etc.

No winglets are added to increase fuel effency. The 145 XR (Xtended Range) also has a center fuel tank for added range.

Winglets are added to reduce the size of wingtip vortices, which cause drag, therefore increasing fuel efficiency which in turn extends range. Also because drag is reduced take off and climb performance generally increases. The lasted added benefit is also usually increase cruise performance. But mind you this increase is usually only a few percentage points which pays off over time. However you need to literally weigh the increase of adding the winglets to adding the weight to the airplane.

I'd say the larger planes were trying to fit in. Weren't the majority of winglets on smaller bizjets to begin with?  Big grin

Yes, I know they're used to help save fuel. That was just a bad attempt to be funny.

Never mind. I was trying to be funny, which I why I put the smiley there.

There are very few things on an airplane that aren't there for a reason.

In addition to the winglets, the XRs have extended range of up to aproximately 2,000 miles. They also have much more powerful engines than any of the other competing aircraft in the family.

Winglets do little to decrease takeoff roll since induced drag is non-existant when the wing is not generating lift.

What's nominal cruise for an ERJ145? 0.76M?

Also, the ceiling is FL350, right?

These look like the same fairings used on a legacy. How big are the baggage "pits" in the back? How often do they run out of space?

How's the on-time performance of IAH-GSO? Maybe it's just my luck, but the other majors seem to have a hard time keeping delays to under 45 min in and out of GSO, never mind out and out cancellations.

Performance
High speed cruising speed 833km/h (450kt). Service ceiling 37,000ft.
ERJ-145ER - Range with 50 passengers at long range cruising speed 2445km (1320nm).
ERJ-145LR - Range with 50 passengers at long range cruising speed 2870km (1550nm).

Yes they are. A legacy is basicly a 135 with winglets and strakes. As far as baggage is concerned you are more likely to leave with the baggage pit part empty due to weight restrictions then full.
