Squawking 7700 in the big wide world of aviation. From my own aviation art and photography to all the little vectors I follow to interesting aviation history......
N573UW here on climb out shows off one of the biggest aerodynamic differences of the Airbus A321 compared to the A320 and A319- on those aircraft the trailing edge flaps are single slotted. But if the longer and heavier A321 had the same single slotted flaps, it would have a flatter takeoff and use more runway as it would need a shallow deck angle at rotation to avoid a tail strike. To avoid this penalty, Airbus put double slotted flaps on the A321- note the smaller flap actuator/track fairings in between the larger fairings- those are unique to the A321 wing. #Avgeek #aviation #aircraft #planeporn #kdfw #dfw #airport #igtexas #planespotting #airlines #megaplane #instaplane #airbus #dfwavgeek #instagramaviation #avgeekery #igaviationcontest #A321 #N573UW #usairways #avgeekschoolofknowledge #instaspotting (at DFW Founders Plaza)

Let’s play with the 1/400 scale man-toys again, this time we have an Aeroflot Tupolev Tu-154B-2 which was one of the last of the early variants powered by the Kuznetsov NK-8 engine before production switched to the turbofan-powered Tu-154M. The NK-8 was comparable to the Rolls Royce Conway engine- it formed the basis of a family of engines, from the NK-86 used on the Ilyushin Il-86 widebody to the NK-144 used on the early versions of the Tu-144 SST. The Tu-154 was once so ubiquitous in Aeroflot’s fleet that half of the passengers flying on Aeroflot were carried on Tu-154s. The Tupolev trijet served with Aeroflot 1971-2009. #avgeek #aviation #aircraft #airlines #planeporn #thechickenport (follow this tag to see more of my collection) #Aeroflot #airlines #aerosanctuary #EICKE #Tupolev #Tu154 #avgeekery #avgeekschoolofknowledge

Its been ages since I last passed through O’Hare- it had to be at least before the O’Hare Modernization Plan kicked in. But I see ORD has seen the light and decided to be like DFW with a bunch of parallel runways, a few diagonals and two control towers, wink-wink. But seriously, here’s a Republic E175 turning onto 28R while a United A320 rotates and a United 737-800 turns off the runway heading to the south on climb out. Soon there’ll be three 28s- 28R pictured here, 28C which opened last fall and 28L which opens fall next year. Lots of changes for ORD- but at least I can still hear Rhapsody in Blue in the tunnel at the United Concourses.   #Avgeek #aviation #aircraft #planeporn #KORD #ORD #OHare #airport #planespotting #airlines #megaplane #instaplane #Embraer #AmericanEagle #Republic #E175 #N430YX #instagramaviation #igaviationcontest #avgeekery #avgeekschoolofknowledge

A little Jungle Jet action for the ERJ crews out there. I’ve always enjoyed my trips on the ERJ, the big wide cabin windows are a plus for a shutterbug like myself and it seems the inner window is more scratch resistant than the inner windows on Boeing’s. Most don’t like the interior dimensions, but I’m a short Asian dude so it’s all good to me. Longest ERJ flight I ever had was IAH-YYZ on a 145XR. This particular leg recently was a 145 ORD-BVT. #Avgeek #aviation #aircraft #planeporn #KORD #ORD #OHare #airport #planespotting #airlines #megaplane #instaplane #Embraer #unitedexpress #ERJ145 #instagramaviation #igaviationcontest #avgeekery

This head on view of a Shuttle America/United Express Embraer E170 tuning onto 28R for departure shows the non-circular fuselage cross section- on the E-Jets, Embraer went with a double bubble design not unlike that used on the DC-8, DC-9, 707, 727, and 737. The floor is where the upper and lower lobes meet and helps bear the pressurization loads of a non-circular cross section. #Avgeek #aviation #aircraft #planeporn #KORD #ORD #OHare #airport #planespotting #airlines #megaplane #instaplane #Embraer #UnitedExpress #ShuttleAmerica #E170 #instagramaviation  #igaviationcontest #avgeekery #avgeekschoolofknowledge

Coming over the top with Matt Chapman and his Mudry CAP 580 mount! In the early 1970s, French engineer Auguste Mudry started developing his first aerobatic aircraft, the CAP 10, from a light trainer designed by Claude Piel that was marketed as a kit aircraft called the Super Emeraude. Mudry strengthened the structure, refined the aerodynamics and added a more powerful engine to create the CAP 10. Over the years of aerobatic competitions and input from championship aerobatic pilots, the CAP line evolved into progressively more nimble and powerful performers with Matt Chapman’s CAP 580 the latest design. Auguste Mudry passed away in 2006 but despite a bankruptcy in 1997, Avions Mudry lives on as part of the Apex Aircraft conglomerate in France. And the CAP name? It was Mudry’s factory outside Paris- “Constructions Aeronautiques Parisiennes”.  #avgeek #aviation #aircraft #planeporn #KAFW #AFW #FortWorth #allianceairshow #airport #texas  #igtexas #fwaas2013 #MudryCAP #CAP580 #MattChapman #ERAU #EmbryRiddle #instagramaviation #igaviationcontest #instadfw #avgeekery #megaplane #instaplane  (at Fort Worth Alliance Airport)

N71411, a United Boeing 737-900ER delivered originally to Continental in January 2002, turns onto 28R for departure while a Spirit A320 lands on 28C in the background. Note the two blanked out windows on the 737, that’s where the mid-cabin lavatory between first and economy is located. The design of this lav was a challenge due to the limited space for the needed system plumbing- I believe in the US, United is the only -900/-900ER operator with the mid cabin lav- there are four total- one up front, one mid cabin and two in the back. I believe Delta and Alaska’s -900ERs have one lav up front and three in the back. From having flown the -900 for the first time this trip, United’s mid cabin lav is a godsend when you have four kids and there’s a beverage cart between you and the rear lavs! #Avgeek #aviation #aircraft #planeporn #KORD #ORD #OHare #airport #planespotting #airlines #megaplane #instaplane #boeing #United #737 #instagramaviation #N71411 #igaviationcontest #avgeekery #AvGeekSchoolofKnowledge #Spirit #Airbus #A320

Now compare this arriving Boeing 737-900ER with the -900 I previously posted and you can see the extra emergency exit behind the wing but ahead of the aft passenger door. Note also the gap in the passenger windows in the forward cabin- that’s the mid cabin lavatory at row 7. Continental at one point was fitting the mid-cabin lav to the 737-800, but those are or should be gone by now on the -800s. United has the mid-cabin lav on both the -900 and -900ER. #Avgeek #aviation #aircraft #planeporn #KORD #ORD #OHare #airport #planespotting #airlines #megaplane #instaplane #boeing #United #737 #instagramaviation #N37468 #igaviationcontest #avgeekery #avgeekschoolofknowledge
