The Southern Entrance To London City Airport
I entered London City Airport by a different route today, taking these pictures as I walked.
Note.
- The route is level.
- It is on the Southern side of Hartmann Road, which is the main entrance road for the airport.
- There is a pedestrian tunnel under Hartmann Road into the airport.
- There are stairs and lifts into the Docklands Light Railway station at the airport.
- The lifts so all the way to the platforms of the DLR.
- The route is level from the lifts to the airport.
This Google Map shows the walk.
Note.
I walked along the path, that runs NW-SE on the Northern side of the various courts and playgrounds.
The entrance to the DLR station is at the South-East end of the path at the junction of Drew and Saville Roads.
This Google Map shows a 3D visualisation of the entrance.
Note.
- The path runs on the North side of the football pitch.
- The Southern entrance is to the right of blue play area.
- Drew Road runs across the entrance.
- It looks like there is a drop-off point for passengers, where the car is parked by the football pitch.
Would it be possible to create a waking route from this Southern entrance to a rebuilt Silvertown station on the Elizabeth Line?
This Google Map shows the area between the Southern entrance to the airport and the footbridge over the Elizabeth Line.
Note.
- The Southern entrance to the airport is in the North-East corner of the map.
- The footbridge over the Elizabeth Line is in the South-West corner of the map.
- The large building in the middle is Drew Primary School.
- Whytes Road, Saville Road and Leonard Street lead between the Southern entrance to the airport and the A112.
I took these pictures of the A112 and the footbridge a few days ago.
I think it would be possible to run a fleet of small electric shuttle buses on the route.

The number of services will increase in May 2023.
World’s First Net Zero Transatlantic Flight To Fly From London in 2023, Powered By The Rolls-Royce Trent 1000
The title of this post, is the same as that of this press release from Rolls-Royce.
These are the three main bullet points.
- World first as Virgin Atlantic wins UK government funding to operate historic London – New York flight
- Rolls-Royce, Boeing, Imperial College London, University of Sheffield, Rocky Mountain Institute (RMI) and ICF also form part of an iconic British-led consortium
- Heralds future of low carbon aviation, with the wider sustainable aviation fuel (SAF) industry potentially creating thousands of UK jobs while supporting delivery of net zero aviation emissions by 2050
Note.
- The flight will take place next year.
- The aircraft will be one of Virgin Atlantic’s flagship Boeing 787s, which are powered by a pair of Rolls-Royce Trent 1000 engines.
- When fully replacing kerosene, SAF can slash lifecycle carbon emissions by more than 70% compared to conventional fossil jet fuel.
- This flight is expected to be fuelled by SAF made primarily from waste oils and fats, such as used cooking oil.
- SAF could create a UK industry with an annual turnover of £2.4bn by 2040, and which supports up to 5,200 UK jobs by 2035.
The flight could be made net zero, if it used 100 % SAF and offset any carbon dioxide produced.
What Is Sustainable Aviation Fuel?
It is also known as Aviation biofuel, which has a comprehensive Wikipedia entry, which has this first paragraph.
An aviation biofuel or bio-jet fuel or bio-aviation fuel (BAF) is a biofuel used to power aircraft and is said to be a sustainable aviation fuel (SAF). The International Air Transport Association (IATA) considers it a key element to reducing the carbon footprint within the environmental impact of aviation. Aviation biofuel could help decarbonize medium- and long-haul air travel generating most emissions, and could extend the life of older aircraft types by lowering their carbon footprint.
Sustainable Aviation Fuel (SAF) can be made in a variety of ways, which are described in the Wikipedia entry.
Could A Plane Run On Kerosene One Flight And SAF The Next?
I suspect that the practicalities of airline operation and schedules and the production and distribution of aviation fuel, will mean that if an airliner can run on both kerosene and SAF would be a great advantage.
This is a paragraph from the press release.
It comes hot off the heels of the world’s first sustainable fuel military transporter flight using 100% SAF, completed by the RAF last month using the iconic Voyager aircraft.
Note.
- The Voyager is an RAF military transport/tanker aircraft based on the Airbus 330 and fitted with Rolls-Royce Trent 772B-B-60 engines.
- Rolls-Royce Trent engines power both the Dreamliner and the Voyager.
- I’m sure that for operational reasons, the RAF would mandate a dual fuel capability.
This press release on the RAF web site, which is entitled Royal Air Force Completes World-First Sustainable Fuel Military Transporter Flight, gives more details of the RAF flight.
Rolls-Royce And Gulfstream Give Wings To Sustainable Business Aviation
The title of this post, is the same as that of this press release from Rolls-Royce.
These are the first two paragraphs of the press release.
Rolls-Royce and Gulfstream Aerospace Corp. are leading the way towards sustainable business aviation by conducting the first original equipment manufacturer test flight of an ultralong-range business jet powered by 100% Sustainable Aviation Fuel (SAF). The test took place on the BR725-powered Gulfstream G650 twin-jet over Gulfstream’s headquarters in Savannah, Georgia.
Demonstrating that current Rolls-Royce engines for business jet and large civil applications can operate with 100% SAF as a full “drop-in” option, this test lays the groundwork for moving this type of fuel towards certification. At present, SAF is only certified for blends of up to 50% with conventional jet fuel and can be used on all current Rolls-Royce engines.
Note.
- The BR725 is described in this Wikipedia entry.
- The Gulfstream G650 is described in this Wikipedia entry.
- All current Rolls-Royce engines can run with blends of up to 50 % SAF and conventional jet fuel.
The BR725 or other engines in the family have other applications.
- It is used in the Bombardier Global Express.
- It was used in the Boeing 717 airliner.
- The military version of the BR725 will be used to re-engine the USAF’s Boeing B52-H Stratofortresses.
- The Dassault Falcon 10X will be powered by a development of the BR725.
I can certainly see, the owners of business jets being very interested in operating a sustainable business jet.
But would the USAF be interested in running a seventy-year-old bomber on 100% Sustainable Aviation Fuel?
The Fuel Used In The Test
This paragraph of the press release describes the fuel.
The SAF that was used in the test consists of two components: HEFA (Hydroprocessed Esters and Fatty Acids), produced from waste fat and waste plant oils by low-carbon fuel specialist World Energy in Paramount, California, and (SAK) Synthesised Aromatic Kerosene made from waste plant-based sugars by Wisconsin-based Virent Inc. This innovative and fully sustainable fuel in development eliminates the need for the addition of further petroleum-based components and enables a 100% drop-in SAF that can be used in existing jet engines and infrastructure without any modifications. This sustainable fuel has the potential to reduce net CO2 lifecycle emissions by about 80% compared to conventional jet fuel, with the possibility of further reductions in future.
That sounds impressive.
A Sustainable Airliner
The Boeing 717 is a hundred seat airliner, with about a hundred still in service. They appear to have a good safety record.
One of the operators is Hawaiian Airlines and might be the sort of airline, that would like to decarbonise their flights.
So might we see some airlines using the Boeing 717 on SAF to attract passengers?
I wouldn’t rule it out and after certifying the engine on the Gulfstream, certification on another type wouldn’t be the most demanding of certifications.
I also think, it is quite likely, that an aircraft manufacturer could use engines in the BR 725 family to create a hundred seat sustainable airliner.
Rolls-Royce And easyJet Set New World First
The title of this post, is the same as that of this press release from Rolls-Royce.
These three paragraphs explain what the two companies have done and are planning to do.
Rolls-Royce and easyJet today confirmed they have set a new aviation milestone with the world’s first run of a modern aero engine on hydrogen.
The ground test was conducted on an early concept demonstrator using green hydrogen created by wind and tidal power. It marks a major step towards proving that hydrogen could be a zero carbon aviation fuel of the future and is a key proof point in the decarbonisation strategies of both Rolls-Royce and easyJet.
Both companies have set out to prove that hydrogen can safely and efficiently deliver power for civil aero engines and are already planning a second set of tests, with a longer-term ambition to carry out flight tests.
The test today was carried out at Boscombe Down and are shown in this picture from Rolls-Royce.
Rolls-Royce AE2100 Hydrogen Demonstrator engine preparing for test at RAF Boscombe Down
Note that the green hydrogen produced using Orcadian winds and tides.
We live in desperate times and I predict that a hydrogen-fuelled and Rolls-Royce-powered easyJet plane, will fly sooner than anybody thinks.
As with athletes, engineers love to be first!
German Startup EVIA AERO Commits To Hydrogen-Powered Britten-Norman Islanders
The title of this post, is the same as that of this article on Simple Flying.
These two paragraphs outline the deal.
EVIA AERO has signed a letter of intent with Cranfield Aerospace Solutions (CAeS) to increase its order for hydrogen modification kits and aircraft. As part of the agreement, the startup airline expects to receive five additional hydrogen modification kits and ten 19-seat aircraft.
The hydrogen modification kits are designed to power the nine-seat Britten-Norman Islander aircraft and come in addition to a previous order with CAeS for 10 kits.
I can remember seeing the Islander prototype at a Farnborough Air Show in the mid-1960s on the BBC with commentary from the iconic Raymond Baxter.
Is Hydrogen The Fuel Of The Future?
The title of this post, is the same as that as this article on Engineering and Technology Magazine.
The article is a must read about hydrogen.
Orders For The Eviation Alice Pass US$ 2 Billion
The title of this post, is the same as that of this press release from Eviation.
This is the first paragraph.
Eviation Aircraft, a manufacturer of all-electric aircraft, today announced that the order book for its world-leading nine-seater all-electric Alice airplane has passed a total value of US$ 2 billion.
$2 billion is a tidy sum and I suspect it ensures that they can now concentrate on its certification program on the way to completing Entry into Service (EIS).
It looks like the day, I will fly in an electric aircraft has come closer.
Portugal’s Sevenair Eyes Up To 6 Heart Aerospace ES-30 Electric Aircraft
The title of this post, is the same as that of this article on Simple Flying.
Some points from the article.
- Sevenair are a Portuguese regional airline.
- Sevenair run several short routes.
- Heart Aerospace has 230 firm orders and a 100 options for the the ES-30.
Heart Aerospace may not have been the first company to fly an electric airliner, but they do seem to be attracting orders.
‘It Was Wonderful’: Eviation’s Alice Electric Airplane Wins Praise After Its First Flight Test
The title of this post, is the same as that of this article on GeekWire.
The long-expected first flight of Eviation Alice has happened.
The flight was only a short one and was described like this in the article.
Alice flew for eight minutes and reached a maximum altitude of 3,500 feet before landing safely back at the airport.
There is also a video in this article on Electrek, which is entitled Watch Eviation’s All-Electric Alice Aircraft First Flight.
This is an important milestone in the history of aviation.
American Airlines Orders 60 Overture Supersonic Jets
The title of this post, is the same as that of this article on The Times.
This is the introductory paragraph.
The revival of supersonic passenger travel, thought to be long dead with the demise of Concorde nearly two decades ago, could be about to take wing as American Airlines has put in an order for 60 aircraft capable of flying at 1.7 times the speed of sound.
The aircraft has changed a bit since I wrote about it in United Airlines Eyes A Supersonic Future With Deal To Buy Boom’s Overture Jets, which was posted in June 2021.
- It now has four engines instead of three.
- Speed has now been disclosed as Mach 1.7, which is slower than Concorde’s Mach 2.04.
Boom envisages its first commercial flights in 2029.
