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......
New aircraft type to I haven’t yet seen at DFW, this is a Korean Air Cargo 777-F, normally this morning cargo departure is a 747-400F or 747-400ERF. The 777-F is derived from the 777-200LR and technically should be a 777-200LRF, but Boeing just calls it a 777-F or 777 Freighter. Korean’s Boeing customer code is B5, so a 777-200 is designated 777-2B5, but their 777 Freighter is designated 777-FB5. #Avgeek #aviation #aircraft #planeporn #nikon #d7000 #kdfw #dfw #airport #airplane_lovers #igtexas #planespotting #airlines #boeing #777 #korean #koreanaircargo #dfwavgeek #instadfw #instagramaviation #HL8285 #avgeekery #avgeekschoolofknowledge  (at DFW Founders Plaza)

QANTAS 7 Heavy starts extending the landing gear once it’s established on the approach for 18R, and lucky me this happens over my suburb. Did you know on early 747-100s the wing landing gear could be extended only as a speed brake? On the gear handle there was an intermediate detent before “gear down” that was labeled “wing gear”. It didn’t last long, most of the time it resulted in the loss of the main gear doors as it was extended too soon and by the time the 747 was at a speed that allowed use of the wing gear detent without losing the doors, the spoilers on the wing were more that sufficient for the job. The wing gear setting was deactivated early on in the 747-100 production run. #Avgeek #aviation #aircraft #planeporn #nikon #d7000 #kdfw #dfw #airport #airplane_lovers #igtexas #planespotting #airlines #megaplane #instaplane #boeing #747 #qantas #dfwavgeek #instagramaviation #VHOEF #avgeekschoolofknowledge #avgeekery #oneworld

This 200-foot bell tower on the campus of my alma mater, the University of Dallas, is named the Braniff Memorial Tower in honor of the founder of Braniff International Airways, Thomas E. Braniff. Braniff had established a foundation with Senator William Blakely (who replaced LBJ in the Senate from Texas after Johnson became JFK’s VP) called the Braniff Blakely Foundation to fund educational and research efforts in Texas. The University of Dallas got $7.5 million from them to expanded the nascent campus which had been founded by Hungarian Cistercian monks who fled Communist persecution following the 1956 Hungarian Revolution. The tower, designed by Texas architect O’Neill Ford, was built in 1966 and named for Tom Braniff. I always thought it ironic that a massive avgeek like myself would end up getting a college degree from a university that owed much to the founder of one of my favorite airlines. #avgeek #aviation #architecture #avgeekschoolofknowledge #universityofdallas #dallas #texas #irving #igtexas #igersdfw #avgeekery  (at University of Dallas)

Because 757, that’s why! What more to say? Okay, so it’s N183AN, delivered in April 1999, retrofitted with blended winglets in May 2006, yada yada yada.

Getting closer to bagging the oldest MD-80 in the American fleet. That aircraft was delivered in 1986, N499AA here was delivered to the airline in 1989 and was a bit famous this past February on Twitter when pics of it at Gate C7 at Baltimore Washington showed a pushback tug embedded in the nose cone. Note the vapor trail coming off the outboard end of the flaps. #Avgeek #aviation #aircraft #planeporn #nikon #d7000 #kdfw #dfw #airport #airplane_lovers #igtexas #planespotting #airlines #mcdonnelldouglas #md80 #american #dfwavgeek #instadfw #instagramaviation #N499AA #avgeekery #avgeekschoolofknowledge (at DFW Founders Plaza)

The first three of American’s 777-300ERs are leased aircraft (N717AN, N718AN, and N719AN) with the rest of the -300ERs in the fleet appear to be purchased new from Boeing. I’ll have to do more digging to see if there are other leased -300ERs in American’s fleet. This is the third of the initial three leased aircraft, N719AN.  #Avgeek #aviation #aircraft #planeporn #nikon #d7000 #kdfw #dfw #airport #airplane_lovers #igtexas #planespotting #airlines #megaplane #instaplane #boeing #777 #american #dfwavgeek #instagramaviation #n719an #instadfw #igaviationcontest #avgeekschoolofknowledge #avgeekery  (at Dallas/Fort Worth International Airport)

N895NN passes abeam Founders’    Plaza on short final for 18R. Note the flush NACA inlet just behind the aft passenger door. That’s the inlet for the APU and at the very apex of the flush inlet is a delta or arrow shaped “wing” that was added to the APU inlet starting in 1977 to channel air into the inlet at altitude so the APU could be started up while inflight. Prior to the addition of this device, air stagnated near the opening just inside the inlet. The device as added smoothed the air, allowing windmilling to assist with the start of the APU turbine. Later on, a small flap was added to the trailing edge of this device- when the APU has to be started up inflight, the flap deflects toward the fuselage 25 degrees, increasing its effectiveness in getting air down the inlet. When it’s not needed, the little flap pivots outward to 0 degrees to minimize drag. #Avgeek #aviation #aircraft #planeporn #nikon #d7000 #kdfw #dfw #airport #airplane_lovers #igtexas #planespotting #airlines #boeing #737 #american #dfwavgeek #instagramaviation #avgeekery #avgeekschoolofknowledge #N895NN (at DFW Founders Plaza)

Depending upon who you ask, the shortfall in performance that doomed the commercial success of the MD-11 was due to McDonnell Douglas going with a derivative wing based on the DC-10 instead of an all-new supercritical wing. The follow-on variant to the MD-11 was the MD-XX program which stretched the MD-11 with a supercritical wing 213 feet in span that had larger winglets. Had the MD-11 had this wing instead of the wing it got, it might have not had the performance issues it had. So why did McDD go with a derivative wing? Cost. The engineering wasn’t ready for the supercritical wing and it would have cost more to incorporate in the design. Time was also of the essence with McDonnell Douglas wanting the MD-11 ready before the competition entered the market- the Airbus A340 and the Boeing 777. It was thought a derivative wing would be cheaper, get the MD-11 to market first, and the company would recoup a greater return on investment. Unfortunately, the performance shortfalls crippled the MD-11’s chances of success with one key customer, Singapore Airlines, canceling their MD-11 orders and airlines like American dissatisfied with the performance. When Boeing was considering an HQ move that ended up being Chicago, Dallas was in the running and legendary American Airlines CEO Robert Crandall reportedly told Boeing head Phil Condit “Come to Dallas so I can tell you in person how unhappy I am with the MD-11!” (this was after the Boeing-McDD merger).  #Avgeek #aviation #aircraft #planeporn #nikon #d7000 #kdfw #dfw #airport #airplane_lovers #planespotting #airlines #ups #mcdonnelldouglas #md11 #instagramaviation #avgeekery #megaplane #instaplane #avgeekschoolofknowledge #igtexas #igersdfw #n284up #igaviationcontest  (at DFW Founders Plaza)

Pushback! Like the DC-10 it’s derived from, the MD-11 has its nose gear leg canted forward a few degrees. This gives the nose gear self-centering ability, not unlike the forward rake angle on motorcycles and bicycle front wheels. Aircraft with vertical nose gear legs usually have the axle a few inches behing the main axis of the nose gear leg to accomplish the same self centering function like a castoring wheel on a shopping cart.  #Avgeek #aviation #aircraft #planeporn #nikon #d7000 #kdfw #dfw #airport #airplane_lovers #planespotting #airlines #ups #mcdonnelldouglas #md11 #instagramaviation #avgeekery #megaplane #instaplane #avgeekschoolofknowledge #igtexas #igersdfw #n284up #igaviationcontest  (at DFW Founders Plaza)
