Flying planes consistently higher or lower than current altitudes could help the aviation industry reach net zero faster, a report has found.
The suggestion is among four goals the industry could adopt to help the sector – a major contributor to climate change – achieve net-zero emissions globally by 2050.
“Aviation stands at a pivotal moment, much like the automotive industry in the late 2000s,” said Prof Rob Miller, director of the Whittle Laboratory at the University of Cambridge. “Back then, discussions centred around biofuels as the replacement for petrol and diesel – until Tesla revolutionised the future with electric vehicles. Our five-year plan is designed to accelerate this decision point in aviation, setting it on a path to achieve net zero by 2050.”
The plan, drawn up alongside the Cambridge Institute for Sustainability Leadership, outlines four steps the researchers say must start immediately and be completed within five years for the sector to remain on track to achieve net zero by 2050.
Eliminating vapour trails – a combination of ice crystals and soot that can follow an aircraft’s path – is the first. About one in 30 flights produces a persistent contrail, which can trap heat and increase aviation’s climate impact.
“Persistent contrails can be avoided by adjusting an aircraft’s altitude in regions where contrails form, known as ice-supersaturated regions. These regions are pancake-shaped – wide but shallow – making altitude changes effective in preventing contrail formation,” the report said.
“Successfully implementing contrail avoidance could reduce the climate impact of aviation by roughly 40 per cent.”
Commercial planes typically fly at an altitude of 31,000 to 42,000 feet.
The second goal is to introduce new policies aimed at achieving efficiency across the existing aviation sector, such as reducing fuel burn by using new aircraft and engine technology.
“However, several bold efficiency measures exist, which are currently hard to access because they involve systems-wide change,” the report said. “If implemented, these measures could reduce fuel burn by up to 50 per cent by 2050.”
Under the third goal, governments would reform sustainable aviation fuel policies, moving beyond purely biomass-based methods to introduce more carbon-efficient synthetic production techniques.
The last of the four goals is to launch 'moon shot' technology demonstration programmes to assess the benefits of transformative technology.
The industry is primarily relying on sustainable aviation fuels to help it reach net zero. But other options should be studied, including long-haul hydrogen aircraft, which would be lighter and remove CO2 emissions from flight, the report said.
“If these goals are not immediately implemented and achieved by 2030, the window for transformation will close, leaving the world to face the escalating climate consequences of a rapidly expanding aviation industry, which is projected to at least double by 2050,” it added. “The urgency of this moment cannot be overstated.”

UAE currency: the story behind the money in your pockets

What you as a drone operator need to know
A permit and licence is required to fly a drone legally in Dubai.
Sanad Academy is the United Arab Emirate’s first RPA (Remotely Piloted Aircraft) training and certification specialists endorsed by the Dubai Civil Aviation authority.
It is responsible to train, test and certify drone operators and drones in UAE with DCAA Endorsement.
“We are teaching people how to fly in accordance with the laws of the UAE,” said Ahmad Al Hamadi, a trainer at Sanad.
“We can show how the aircraft work and how they are operated. They are relatively easy to use, but they need responsible pilots.
“Pilots have to be mature. They are given a map of where they can and can’t fly in the UAE and we make these points clear in the lectures we give.
“You cannot fly a drone without registration under any circumstances.”
Larger drones are harder to fly, and have a different response to location control. There are no brakes in the air, so the larger drones have more power.
The Sanad Academy has a designated area to fly off the Al Ain Road near Skydive Dubai to show pilots how to fly responsibly.
“As UAS technology becomes mainstream, it is important to build wider awareness on how to integrate it into commerce and our personal lives,” said Major General Abdulla Khalifa Al Marri, Commander-in-Chief, Dubai Police.
“Operators must undergo proper training and certification to ensure safety and compliance.
“Dubai’s airspace will undoubtedly experience increased traffic as UAS innovations become commonplace, the Forum allows commercial users to learn of best practice applications to implement UAS safely and legally, while benefitting a whole range of industries.”
Keep it fun and engaging
Stuart Ritchie, director of wealth advice at AES International, says children cannot learn something overnight, so it helps to have a fun routine that keeps them engaged and interested.
“I explain to my daughter that the money I draw from an ATM or the money on my bank card doesn’t just magically appear – it’s money I have earned from my job. I show her how this works by giving her little chores around the house so she can earn pocket money,” says Mr Ritchie.
His daughter is allowed to spend half of her pocket money, while the other half goes into a bank account. When this money hits a certain milestone, Mr Ritchie rewards his daughter with a small lump sum.
He also recommends books that teach the importance of money management for children, such as The Squirrel Manifesto by Ric Edelman and Jean Edelman.

How Voiss turns words to speech
The device has a screen reader or software that monitors what happens on the screen
The screen reader sends the text to the speech synthesiser
This converts to audio whatever it receives from screen reader, so the person can hear what is happening on the screen
A VOISS computer costs between $200 and $250 depending on memory card capacity that ranges from 32GB to 128GB
The speech synthesisers VOISS develops are free
Subsequent computer versions will include improvements such as wireless keyboards
Arabic voice in affordable talking computer to be added next year to English, Portuguese, and Spanish synthesiser
Partnerships planned during Expo 2020 Dubai to add more languages
At least 2.2 billion people globally have a vision impairment or blindness
More than 90 per cent live in developing countries
The Long-term aim of VOISS to reach the technology to people in poor countries with workshops that teach them to build their own device
What is blockchain?
Blockchain is a form of distributed ledger technology, a digital system in which data is recorded across multiple places at the same time. Unlike traditional databases, DLTs have no central administrator or centralised data storage. They are transparent because the data is visible and, because they are automatically replicated and impossible to be tampered with, they are secure.
The main difference between blockchain and other forms of DLT is the way data is stored as ‘blocks’ – new transactions are added to the existing ‘chain’ of past transactions, hence the name ‘blockchain’. It is impossible to delete or modify information on the chain due to the replication of blocks across various locations.
Blockchain is mostly associated with cryptocurrency Bitcoin. Due to the inability to tamper with transactions, advocates say this makes the currency more secure and safer than traditional systems. It is maintained by a network of people referred to as ‘miners’, who receive rewards for solving complex mathematical equations that enable transactions to go through.
However, one of the major problems that has come to light has been the presence of illicit material buried in the Bitcoin blockchain, linking it to the dark web.
Other blockchain platforms can offer things like smart contracts, which are automatically implemented when specific conditions from all interested parties are reached, cutting the time involved and the risk of mistakes. Another use could be storing medical records, as patients can be confident their information cannot be changed. The technology can also be used in supply chains, voting and has the potential to used for storing property records.

Types of bank fraud
1) Phishing
Fraudsters send an unsolicited email that appears to be from a financial institution or online retailer. The hoax email requests that you provide sensitive information, often by clicking on to a link leading to a fake website.
2) Smishing
The SMS equivalent of phishing. Fraudsters falsify the telephone number through “text spoofing,” so that it appears to be a genuine text from the bank.
3) Vishing
The telephone equivalent of phishing and smishing. Fraudsters may pose as bank staff, police or government officials. They may persuade the consumer to transfer money or divulge personal information.
4) SIM swap
Fraudsters duplicate the SIM of your mobile number without your knowledge or authorisation, allowing them to conduct financial transactions with your bank.
5) Identity theft
Someone illegally obtains your confidential information, through various ways, such as theft of your wallet, bank and utility bill statements, computer intrusion and social networks.
6) Prize scams
Fraudsters claiming to be authorised representatives from well-known organisations (such as Etisalat, du, Dubai Shopping Festival, Expo2020, Lulu Hypermarket etc) contact victims to tell them they have won a cash prize and request them to share confidential banking details to transfer the prize money.
