Mango Introduces Split Scimitar Winglets
We were kindly invited by Mango’s Grant Timms to witness the first test flight as Mango (One of South Africa’s low cost airline) introduced the first of eight aircraft that will have the Split Scimitar Winglets fitted to their fleet.
In what will be its first widespread commercial use, Split Scimitar Winglets have officially been giving the go-ahead to grace Boeing 737-800s all across the world. While winglets themselves are nothing new, this more aerodynamic incarnation should cut fuel costs by 2%—in other words, pushing their total winglet-related savings to $200 million.

Inspired by the scimitar, the new winglets retrofit a blended ventral fin to the plane’s wings, essentially making it look like two very thin (and presumably self-loathing) dolphins jammed themselves head first into either side of the plane. Because it makes use of both the split/ventral singlet design and the high-performance scimitar tips, United has managed a cruise performance gain of 30-40%. So how do these winglets manage to reduce so much drag?
Because winglets curve upward, the higher air pressure on the wing’s lower surface flows toward the tip and curls with the winglet. Since the air is pushed upward, this reduces the vortex and subsequent energy loss that is created by air flowing around the wingtip. The split design of the new ones, then, further reduce the vortices formed behind the wing, which in turn further reduces energy loss.

British Airways and the B747 BOAC Liveries
By Niel Swart
We all have our special airplane, the one that makes you stop and look when you here the rumbling of an engine but there is only one that is truly the queen of the skies… the Boeing 747.
The month of February will be a special one as the 9th will see the 50th birthday of the queen. She appeared in movies, series, printed media, social media, toys, puzzles, balloons, birthday/retirement cakes and many will remember the 1995 Ruby World Cup final, Ndizani, 3 Boeing 747’s over the Union Buildings, their first Boeing 747 flight or the first time ever they saw a Boeing 747. She is basically everywhere and this shows the impact she made on everyday life as we know it. To make things more special, every now and then, we as aviation lovers are treated to a special livery Boeing 747.

Not only is February the birthday of the Boeing 747 but also the birthday of an icon. A nation’s pride, an airline… British Airways. Yes, they will be celebrating their 100th birthday this year. Of course, the British will celebrate like only the British can with special uniforms, official celebrations and the cherry on top for us, a special livery Boeing 747. Not just any special livery… an BOAC (British Overseas Airways Corporation) livery. Yes, you read it correctly… an BOAC livery. This means that G-BYGC will be gracing the skies in BOAC colours as of 18 February when she will leave Dublin as a newly painted Boeing 747 to return to scheduled service as of 19 February until she retires in 2023. As if this is not enough celebrating, G-BYGC will be 20 years with British Airways. At present she mostly does the transatlantic legs but British Airways did hint at the fact that she will be sent on scheduled flights to as many as possible destinations. So there is a chance we may see here either at Johannesburg or Cape Town.

If you thought that was the end, guess again. British Airways announces new 100 year related bits of information often and it is said that at least another 2 Boeing 747’s are to receive retro liveries until they retire. This has not been confirmed as yet but the grapevine is suggesting G-BNLY and G-CIVB will also receive retro liveries until their retirement. G-CIVB being a frequent visitor to the Cape.
So definitely set alerts on your favourite live flight tracking app for these airplanes as you do not want to miss them if they visit and they have a retro livery.
