> Did you know a 747 could carry an additional engine? The 5th engine is not working: it is carried as cargo underneath the wing to transport it from one location to another. This special way of carrying the engines is mainly used to transport an engine to an already broken down aircraft at a non-base airport. The second 747 can fly in a new engine, after which engineers can replace the engine on the broken down 747. The broken engine can be carried back in the same way to the home base airport. > > Due to the drag, the performance of the aircraft is quite heavy impacted. Crews must plan additional fuel stops to account for the added fuel burn. > > See for more information and a very nice description of this process this blog from Flightradar24.

> SA Novespace of France operates an Airbus A310 (F-WNOV) to perform 'parabolic' flights. During these flights, the aircraft simulates weightlessness for a short period of time. The cabin of the aircraft is therefore mostly empty, to give people the space to float around. > > Astronauts from ESA use these flights to prepare themselves for weightlessness in space. See for an image what parabolic flight maneuvers are: https://www.researchgate.net/profile/Paolo-Lunghi-2/publication/314285521/figure/fig2/AS:469569253974026@1488965442721/Parabolic-flight-sequence.png

> General Electric owns a 747-400 (N747GF). This aircraft is used to test new engines in-flight. For example the one in the photo: the new GE9XTM engine, which will be used on the new Boeing 777X. What a size difference compared to the CF6s of the 747! > > This frame was orginally delivered to Japan Airlines in March of 1994 with registration JA8910. GE bought it in January 2011 to replace the aging Boeing 747-100 (N747GE). The 747-100 was orginally delivered to Pan Am in 1970 as 25th 747 off the line. GE bought it in March of 1992 and has used it until January 2017. The N747GE is currently on display at Pima Air and Space Museum (Tucson Davis-Monthan AFB)

> Air India owned several A320 aircraft with double wheels. By default, all A320s are delivered with a singe-wheel setup by Airbus. Back in the early 90s, Air India wanted to operate A320s to airports in India which could not carry the weight of an A320 on the ramps and taxiways. To help distribute the weight more evenly, Air India asked Airbus to design and deliver double-wheeld A320s. Several A320s were delivered with double-wheel setup in the early 90s to Air India. > > Nowadays, the infrastructure in India has vastly improved and the weight constraint is no longer in place. Air India has stored or scrapped all double-wheel A320s. > > This is a post in a serie of aircraft odd-variants. If you like it: please upvote it :)

> I am starting a small series on the "odd variants" of some aircraft types. This is the first post 🙂 Please upvote if you would like to see more ✈️ > > Honeywell owns a 757-200 with RR-engines. They have fitted their 757 with a small, 3rd, wing to test avionics, engines and other instruments. So far it has carried a jet engine, prop engine and instruments.. > > It is an early 757 from 1983: the 5th delivered 757. Delivered to the now defunct Eastern Airlines. Honeywell aquired it in 2005 as N757HW. > > Picture source // aeroprints.com
