Airway Lighting and Radar Navigation Aids: A Brief History

Published

During the early days of aeroplanes, there have been no navigational tools to assist pilots. With a map in hand, the pilots flew while observing their cockpit window or visual signals. For day flights, these visual clues, often known as maps, were acceptable, but airmail would run at all hours.

Windsocks brightened the location in July 1923, and revolving beacons atop the tower had taken root. The Postal Service has been working on completing a transcontinental air tag on towers that are located between 15 and 25 miles apart and bright enough to be seen from 40 miles away in clear weather since 1923. By the first week of July 1924, the postal service had resumed normal service along sections of the route. In 1926, the Departments of Aeronautics and Commerce were given the task of constructing airways with lights. Around 4,121 kilometres of runways had lighting by June 1927. In 1933, there were 18000 miles (28968 kilometres) of the runway and 1500 beacons.

The Department of Aeronautics added a new group of radio stations to the seventeen they had obtained from Postal Services in October of 1928. There were 68 separate stations where pilots might acquire navigation applications via radio communication. Radio navigation beacons were also created by the Department of Standards. The Department of Aeronautics issued standard four in 1929, requiring pilots to listen to auditory signals to assess whether or not they are on track. Through the Second World War, the Directorate of Aeronautical hastened the ability to establish four radio-race ranges; this technology had become the norm for public aviation.

The Civil Aeronautics Administrations (CAA) opened the first radio-frequency ultra-high range for the air navigation system planned in May 1941, potentially extending the usage of this sort of equipment over 35,000 miles of federal airspace. The CAA tested static-free and very-high-frequency (VHF) omnidirectional radio ranges (VOR) in 1944, during the war, with the advancement of radios, allowing pilots to navigate by viewing the dial on the dashboard rather than listening to radio signals.

Until mid-1952, 45000 miles (72420 kilometres) of airspace and VHF VOR, known as the Victor airway, supplemented the Federal Act’s 70000 miles (112654 kilometres) of the low-frequency airway. The CAA has begun to restrict four bands of low and medium frequency radio transmissions.

The 16 waterways surfaces were developed in October of 1969. Previously, pilots flew straight toward or away from the ground-based radio. This assistance has sent a voyage via the radial invisible lines. There were around 156 high-altitude navigation zone legs available in 1973.

The Federal Aviation Administration (FAA) requested the government and industry investigations of the idea of Free Flight in October 1994, which might allow pilots to choose the most efficient routes between aids to navigation. The FAA and its industry partners had started to restrict the use of some of the concept’s functionalities. More navigation technologies, such as Global Positioning Systems (GPS) to help identify and control aircraft satellites, as well as communications, navigational, and surveillance systems to aid air traffic control, were partially approved for use or development.

UPI for Feature Phones from RBI

Published

On Tuesday, the Reserve Bank of India (RBI) announced UPI123Pay, a new digital payment option for feature phones based on the Unified Payments Interface (UPI). The UPI system has so far been restricted to smartphones with internet access. India’s mobile phone population is estimated to be at 180 million. 78 crore of these people have smartphones, while the remaining 78 crores have feature phones. Due to the phone they use, tens of thousands of users have been unable to do UPI transactions. The central bank of India introduced this new payment mechanism to incorporate all such users and bring them into the mainstream of digital payments.

“UPI123Pay would enable NPCI to accomplish its goal of a billion or more daily UPI transactions,” said Biswamohan Mahapatra, head of the National Payments Corporation of India (NPCI), the country’s umbrella organization for retail digital payments.

Working of UPI on Feature Phones?

Users will be able to conduct UPI transactions on feature phones using UPI 123Pay. Except for the scan and pay UPI option available for smartphones, consumers will be able to use all other functionalities. Transactions with the new digital payment mode don’t require an internet connection. To utilize the UPI 123Pay service, people must link their bank accounts to their feature phones. People with feature phones can now use the UPI 123Pay option for a variety of payments, from person to person to the merchant. UPI 123Pay would employ Hindi and English as their primary languages at first.

“We feel that the novel functions available on feature phones would give UPI a boost in many geographies across the country, transforming the way payments are perceived,” Mahapatra said.

UPI: India’s Most Popular Payment Method

In recent years, UPI has become one of India’s most popular payment methods. UPI is the country’s single largest retail payment system in terms of transaction volume.

“A substantial portion of digitalization is limited to people with smartphones, notwithstanding our tremendous growth in digital payments.” “About 40 crore feature phone users had limited access to digital payments,” said T Rabi Sankar, deputy governor of the Reserve Bank of India. He stated that the goal is to attract a significant number of feature phone users into the UPI payment system.

“To further popularise the usage of digital payments, a framework for retail offline payments across the country has been proposed.” This announcement has its roots in a series of successful pilot studies. The results of these experiments strongly suggest that there is more leeway for digital payment-related solutions, particularly in rural areas. According to Nitin Mathur, CEO of Tavaga Advisory Services, “the RBI is enthusiastic about expanding the ease of doing business in India as well as more innovative fintech prospects to capitalize on” as a result of this development.

According to Livemint, the Indian Railway Catering and Tourism Corporation (IRCTC) has partnered with e-payment provider Paytm to provide ticketing services through Automatic Ticket Vending Machines at railway stations in order to make travel easier for commuters. According to reports, the service has already begun at all Automatic Ticket Vending Machines (ATVM) in Indian railway stations. Passengers will be able to pay for tickets using digital methods and commute fully cashless as a result of this.

Customers can make payments using Paytm Wallet, Paytm UPI, Net Banking, Debit Card, Credit Card, Net Banking, and Paytm Post-paid, among other methods (Buy Now, Pay Later).

The touchscreen ATVMs installed at train stations let passengers purchase tickets using UPI rather than a smart card. Passengers must scan the QR code displayed on the ATVM screen in order to access the service. After scanning, passengers can quickly purchase platform tickets, unreserved train journey tickets, recharge smart cards, and renew seasonal tickets.

“Firstly tested the QR code revolution in India, we are happy to carry it forward by offering the convenience of ticketing across railway stations,” a Paytm representative said. He went on to say that Paytm’s relationship with IRCTC will provide QR solutions to Indian Railways’ Automated Ticket Vending Machines. And, he noted, this will enable people to go totally cashless when purchasing tickets.

Follow the instructions below to utilize the ATVMs’ digital payment feature at train stations.

First, find an ATVM at your local train station.

Step 2: Using the touchscreen, choose a route for reserving a ticket or enter a smart number for recharging.

Step 3: Make your payment using any Paytm option.

To complete the transaction, scan the QR code generated on the screen.

Step 5: Depending on your choices, a physical ticket or a smart card recharge will be generated.

WhatsApp is focusing on improvements to its user interface. The chat application was recently caught developing a new profile cover photo that looks like it belongs on Facebook. Users can now add covers to their WhatsApp profiles, according to a new feature discovered recently. The functionality is intended for use by businesses. WhatsApp’s library is anticipated to benefit from the new capability.

WhatsApp users will soon be able to customise their profile covers, according to Wabetainfo. This feature, however, will be available only to WhatsApp Business accounts; normal user accounts would not be able to use it. According to the article, beta testers will be able to use the feature, and your business profile settings will be altered.

According to a screenshot obtained by Wabetainfo, WhatsApp intends to add a new camera button to your Business Settings. Like the cover photo, you can choose an existing photo or take a new one. Your cover photo will be visible to everyone visiting your business profile (including ordinary WhatsApp user accounts).

On WhatsApp on iOS beta, the feature was discovered to be in the testing phase. WhatsApp Business for Android will get the same feature as well. A release date for the feature is unknown because it is still in development.

Aside from that, WhatsApp has been seen developing a new voice call interface. Since December 2021, the messaging app is said to have been working on a new interface. The user interface for both the iOS and Android apps was previously built. However, for Android beta testers, WhatsApp has recently released a revamped calling experience.

WhatsApp is updating its caller interface not only for individual conversations but also for group calls.

When you make a group voice call, bring voice waveforms for all participants during the call, as seen in the screenshots. The new upgrade is being sent out to Android beta testers today, according to Wabetainfo, with more activations expected in the following weeks. The new UI has yet to be seen on the iOS beta app, but according to the features tracker, WhatsApp may receive it in a future release.
