One of Zip's brightly colored Boeing's seen on final into Calgary Int'l Airport in Canada

Compared to the wing of the A319 and A320, the Airbus A321’s wing not only has both outboard and inboard double slotted flaps compared to the A319/A320’s single slotted flaps, but there is also a tapering chord extension on the trailing edge of the outboard wing and a constant chord extension on the trailing edge of the inboard wing, adding up to a 4 square meter increase in wing area.⁣ ⁣ The double slotted flaps also call for the extra actuators that are in the smaller extra flap fairings that the A319/A320 wing lacks. ⁣ ⁣ It’s not the most ideal flap arrangement for the heavier and longer A321- if it had single slotted flaps like the rest of the family, the degree of rotation needed at takeoff would result in a tail strike. A slight chord increase and change to double slotted flaps were as far as what could be done and still retain significant production and parts commonality with the rest of the A320 family while eliminating the tail strike issue.⁣ ⁣⁣⁣ This is C-GJWD, originally delivered to Air Canada in May 2002. As of November 2019, Air Canada has 15 Airbus A321s in their fleet. The most numerous type in Air Canada’s fleet is the Boeing 787 (37) and the A320 (37). The second most numerous type at Air Canada is the Boeing 777 (25), followed by the 737MAX (24). ⁣⁣ ⁣ #Avgeek #aviation #aircraft #planeporn #CYYC #YYC #Calgary #Alberta #airport #planespotting #instaplane #Airbus #instagramaviation #A321 #AirCanada #CGJWD #splendid_transport #instaaviation #aviationlovers #aviationphotography #flight #AvGeeksAero #AvgeekSchoolofKnowledge #AvGeekNation #TeamAvGeek (at YYC Calgary International Airport) https://www.instagram.com/p/B4gleG3httG/?igshid=19qagkudrg7af

The Boeing 737-200 wing was pretty much designed for the weight of that variant and when the 737-300/400/500 arrived, aerodynamic tweaking of the wing was necessary (like a 4% increase in chord)- but the wing wasn’t all that much a departure from the -100/200 wing in the interests of commonality and reduced development costs and as such, so wing loading went up. ⠀ ⠀ At max takeoff weight, a 737-200 wing is loaded to 132 lbs per square foot. By comparison, a 737-300 at max takeoff weight has a wing loading of 122 lbs per square foot- the lower wing loading thanks to aerodynamic tweaks means the longer 737-400 has the same wing loading as the shorter 737-200. ⠀ ⠀ When the 737NG program came along, it got an all new supercritical wing that was not only larger, but had lower drag, the design heavily influenced by the 777’s wing design. One of the side benefits of the new wing was room for about 30% more fuel, giving a significant range boost to the NG variants. ⠀ ⠀ A 737-700 at max takeoff weight has a wing loading of only 115 lbs per square foot. This meant there was considerable growth potential in the NG wing. In fact, a 737-800 at MTOW has a lower wing loading than a 737-200 (129 lbs/sq ft versus 132 lbs/sq ft). ⠀ ⠀ And if you’re curious, I crunched the numbers on the wing loading for a 737-900ER at MTOW: 139 lbs/sq foot.⠀ ⠀ This particular split scimitar-equipped Boeing 737-800 of Westjet, C-GKWJ, heading out at Calgary, happens to also be Westjet’s very first 737-800 (Ship 801), delivered to the airline in April 2005. ⠀ ⠀ #Avgeek #aviation #aircraft #planeporn #CYYC #YYC #Calgary #Alberta #Canada #airport #planespotting #airlines #Boeing #737 #Westjet #CGKWJ #instagramaviation #instaplane #splendid_transport #instaaviation #aviationlovers #aviationphotography #flight #aviationnation #aviationphotography #AvgeekSchoolofKnowledge #AvGeekNation (at YYC Calgary International Airport) https://www.instagram.com/p/B5g8-6LhK9Y/?igshid=1vej26xvj0p0r

This C-GPWS, Ship 601, Westjet’s first Boeing 737-600. Westjet currently (as of 4Q2019) has thirteen 737-600s in their fleet which were delivered August 2005 to September 2006- they also have the last 737-600 built as well. Westjet’s 2004 order quite literally brought the 737-600 back from the dead- the variant had no orders placed from December 1999 to May 2004 until Westjet came along. Launch customer was SAS with their first one being delivered in January 1999. ⠀ ⠀ SAS recently retired their 737-600s, the last SAS -600 flight being made on 30 November 2019. SAS’s launch order was a major coup for Boeing as the -600 beat out the BAe-146, A319, and MD-95. The -600s were the ideal replacement for the 737-500s inherited from the acquisition of Braathens which also came with 737-700s. ⠀ ⠀ Westjet also had some thin routes not unlike SAS’s network. Fleet commonality made the 737-600 a natural choice with they other 737NG variants in the Westjet fleet. ⠀ ⠀ Only 69 were built and compared to the 737-700, it has pretty much the same operating costs but they’re spread out over smaller passenger numbers, giving the -600 higher seat-mile costs, a common drawback with airframe shrinks. In general, variants that are longer (more passengers means lower seat mile costs) do better. ⠀ ⠀ I’d argue that the 737-600 is more of a niche aircraft than a failure. The biggest operators, SAS and Westjet, already had other 737NG variants in their fleet and needed a common type for crew and maintenance simplification but more suited to thinner routes. Only three years separated the launch order from SAS to the first delivery, so it was a minimum risk/cost derivative to bring to market. Interestingly Westjet had originally planned to get blended winglets with their -600s but announced in 2006 that they were going to focus on winglets for the -700/800 fleet only. ⠀ ⠀ #Avgeek #aviation #aircraft #planeporn #CYYC #YYC #Calgary #Alberta #Canada #airport #planespotting #airlines #Boeing #737 #Westjet #CGPWS #instagramaviation #instaplane #splendid_transport #instaaviation #aviationlovers #aviationphotography #flight #aviationnation #aviationphotography #AvgeekSchoolofKnowledge #AvGeekNation (at YYC Calgary International Airport) https://www.instagram.com/p/B5oKgYVhsIX/?igshid=x5ycwa9krc6b

This Bombardier CRJ200 of Jazz operating as Air Canada Express pulls into the terminal at Calgary International Airport. At one time not long after the CRJ first entered service, the CRJ flew for Air Canada’s mainline for a brief time. The US and Canada signed an open skies agreement in 1995 and to build up cross-border flights from its Canada hubs quickly, Air Canada operated 26 CRJ100s for a short time. It was an unusual set up as most airlines of the time that were getting CRJs were regional partners to large mainline carriers, but for Air Canada, it was a way of building up cross border business into the United States with a lower up front cost. I was living in Kansas City at the time and my first flight on the CRJ was on one of Air Canada’s new cross border flights that connected Kansas City to Toronto Pearson (MCI-YYZ) back in the summer of 1998. The aircraft weren’t popular with passengers due their cramped interiors and I was much relieved on the return to Kansas City when flight delays resulted in getting shifted over to a United A319 flight via Chicago back to Kansas City. The CRJ100s used by the Air Canada mainline were the first Canadian built aircraft used by Air Canada since the Canadair North Stars of the 1940s which were Douglas DC-4s powered by Rolls Royce Merlin engines. #Avgeek #aviation #aircraft #planeporn #CYYC #YYC #Calgary #airport #planespotting #airlines #Bombardier #CRJ #CRJ200 #AirCanadaExpress #Jazz #CGUJA #instagramaviation #Avgeekery #AvgeekSchoolofKnowledge (at YYC Calgary International Airport)
