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......
The Ivchenko-Progress AI-25 engine that powers the Aero L-39 Albatros first ran in 1965 and flew first in 1966 as the powerplant of the Yakovlev Yak-40 trijet airliner. As what was essentially a jet-powered DC-3 replacement, the AI-25 had to be robust, easy to maintain but economical as the Yak-40 was expected to operate from austere locations. This called for a turbofan and the AI-25 became the first Russian small turbofan. It formed the basis of the more powerful AI-25TL that first flew on the L-39 in 1972 with an expanded high pressure stage and modifications to allow for aerobatic flight. #avgeek #aviation #aircraft #planeporn #kafw #afw #fortworth #allianceairshow #airport #texas #igtexas #fwaas2013 #aero #l39 #albatros #instagramaviation #igaviationcontest #instadfw #avgeekery #igaviationcontest #blackdiamondjetteam #avgeekschoolofknowledge (at Fort Worth Alliance Airport)

Dusk at Concourse C at Chicago O’Hare. The last time I passed through ORD was long before the merger. Kinda weird seeing all the Continental tails everywhere, wink-wink nudge-nudge.  #Avgeek #aviation #aircraft #planeporn #KORD #ORD #OHare #airport #planespotting #airlines #megaplane #instaplane #boeing #United #737 #instagramaviation #N23708 #igaviationcontest #avgeekery

When the Blue Angels first converted to F/A-18 Hornet, a lot of what the Hornet could do in an air show routine was still unknown, so the A-4 Skyhawk routine was adopted for the Hornet show as a safety measure. Some A-4 routines, though, just didn’t look good from the ground and one in particular was the formation dirty roll where the Skyhawks in diamond formation would each roll 720 degrees while in carrier approach landing configuration. According to one Blues pilot from that time “it was ugly, it looked like we had airplanes going all sorts of ways”. The solo pilots had been working on exploring a dirty loop and pointed out that the Hornet was easy to loop in carrier approach configuration thanks to its powerful engines, so why not do a formation dirty loop? And the Diamond Dirty Loop maneuver was born. The Blues needed a waiver, though- the max speed with gear down is 250 knots, on the back of the diamond dirty loop, the formation hits 300 knots and needed a waiver to exceed the 250 limit not to mention extra attention to the gear doors after the show by the maintenance troops! #avgeek #aviation #aircraft #planeporn #nasfortworthjrb #nfw #carswell #fortworth #airport #texas #airplane_lovers #igersdfw #airpowerexpo2014 #igtexas #mcdonnelldouglas #fa18 #hornet #blueangels #instaplane #megaplane #instagramaviation #igaviationcontest #avgeekery #avgeekschoolofknowledge

When Beechcraft created the King Air series, their desire was for a robust and efficient modern twin that would replace the Beech 18 in a variety of roles. When you consider that the Beech 18 was in production for 35 years and the 90-series King Air pictured here has been in production 50 years and is still being produced, it’s a pretty safe bet to say that Beechcraft got their wish with the King Air family! #Avgeek #aviation #aircraft #planeporn #kads #ads #addison #airport #igtexas #planespotting #beechcraft #kingair #kingairnation #C90 #megaplane #instaplane #instadfw #instagramaviation #avgeekschoolofknowledge #avgeekery #instaspotting #igaviationcontest (at Addison Airport (ADS))

The placement of the 747 cockpit on an upper deck hump is in some measure a reflection of where Boeing thought the future of air travel was headed, but not towards double deck airliners. Boeing thought the 747 would be something of a placeholder until the real future of air travel arrived with supersonic transports and the 747 would be relegated to the cargo role. A full length main deck with the cockpit above would make a re-roled 747 attractive on the cargo market. Didn’t unite turn out that way but the design of the 747 still made it a popular cargo aircraft in its own right which only now is reaching its twilight years with big cargo twins like the 777F entering service. #Avgeek #aviation #aircraft #planeporn  #kiad #iad #dulles #airport #airplane_lovers #planespotting #airlines #megaplane #instaplane #boeing #lufthansa #747 #instagramaviation #DABYC #igaviationcontest #avgeekery #avgeekschoolofknowledge

The airfoil of the Boeing 737 Classics isn’t just one cross section for the wings but rather four different Boeing developed airfoil sections as you move from the wing root outward to the wingtip. The same arrangement is used on the 737-100/200 only with the outermost airfoil section modified for the Classics. It’s not an unusual arrangement for Boeing’s jets- the 707 series did something similar and the 727 has five different airfoil sections across its wing. The 737NG family, though, has a new supercritical airfoil section. #Avgeek #aviation #aircraft #planeporn #kaus #aus #airport #airplane_lovers #igtexas #planespotting #airlines #boeing #737 #southwest #swapic #bergstrom #instagramaviation #avgeekery #avgeekschoolofknowledge #austin #instaspotting

Black tipped radomes are so old school- even amongst military aircraft they’re much less common than they once were. This is because for the longest time the main color radar-passive (transparent) paint came in was black and for the MD-80, most early deliveries until much later on had these black tipped radomes (a friend once called them nipple noses!) until other colors of radar passive paint became more widely available and at lower costs. Since the radomes move around the fleet, having one of these nipple noses isn’t a guarantee that you’re looking at an older MD-80 airframe. #Avgeek #aviation #aircraft #planeporn #KDFW #DFW #airport #igtexas #planespotting #airlines #megaplane #instaplane #McDonnellDouglas #MD80 #american #dfwavgeek #instagramaviation #N16545 #avgeekschoolofknowledge #avgeekery (at DFW Founders Plaza)

Contrary to common belief, flown in the right way, the Curtiss P-40 Warhawk could effectively battle the vaunted Zero. The Flying Tigers in China astutely realized the P-40 had a climb and speed advantage and used their P-40s in slashing attacks, avoiding the turning fight with the more nimble Zero. Later in the Pacific campaign, USAAF pilots would use a low yo-yo, trading altitude for an increased rate of turn which dropped the nose into a turn and done right, the P-40 could cut inside a Zero’s turn. The bigger ailerons of the Zero that gave it outstanding roll maneuverability were also a liability as Warhawk pilots would keep their speed up during dogfights- the higher speeds put higher dynamic loads on the Zero’s ailerons, making the aircraft sluggish. Similar tactics were used in Vietnam against the nimble MiGs- lacking boosted controls, at the higher speeds the MiG-17 lost its maneuverability advantage and American pilots used the speed advantage of their bigger jets against the MiGs. #Avgeek #aviation #aircraft #planeporn #kads #ads #addison #warbirdsoveraddison #airport #igtexas #squareready #planespotting #megaplane #instaplane	 #instagramaviation #curtiss #p40 #warhawk #igaviationcontest #avgeekschoolofknowledge #avgeekery  (at Addison Airport (ADS))

The slot position of the Black Diamond Jet Team is flown by USAF Reserve F-16 instructor pilot Lt Col Sean Gustafson who is also a VP at Draken International. He also flew the MD-88, 757, and 767 for Delta and several years ago became the first USAF Reservist to fly for the Thunderbirds, flying the slot as Thunderbird 4. #avgeek #aviation #aircraft #planeporn #kafw #afw #fortworth #allianceairshow #airport #texas #igtexas #fwaas2013 #aero #l39 #albatros #instagramaviation #igaviationcontest #instadfw #avgeekery #igaviationcontest #blackdiamondjetteam #avgeekschoolofknowledge  (at Fort Worth Alliance Airport)
