An Air India Boeing 787 aircraft with flight number AI 934 from Dubai to Cochin had to be diverted to Mumbai due to cabin pressurisation loss, adding to the growing number of flights that had to be diverted due to technical snags.

The aircraft was cruising at 37,000 feet when the issue occurred and saw oxygen masks being deployed with some of the passengers suffering nosebleeds. The pilots immediately contacted the integrated operations control centre (IOCC) of the airline as well as the air traffic controller.

Following the depressurisation, the pilots descended the aircraft to 10,000 feet. The plane was allowed to divert to the nearest airport, which in this case was the one in Mumbai and it landed safely.

“The captain reported the pressurisation loss to the Air India Integrated Operations Control Centre, and diverted the flight to Mumbai,” a DGCA official said. There were 247 passengers and 11 crew members on board.

The flight had landed safely at Mumbai's Chhatrapati Shivaji Maharaj international airport. As per the information by the Directorate General of Civil Aviation (DGCA), senior officers of O/o DAS WR are assigned the task to carry out a preliminary investigation.

The aircraft was cruising at 37,000 feet when the issue occurred and saw oxygen masks being deployed with some of the passengers suffering nosebleeds.

While most jets have cabin air pressure equivalent to that experienced at an altitude of 8000 ft, the Dreamliner with its composite fuselage can maintain a lower cabin pressure of about 6,000 ft.

The alternate aircraft arranged for passengers of the Dubai-Kochi Air India flight that got diverted to Mumbai a day ago due to a loss of cabin pressure landed at the Cochin International Airport here early on Friday, July 22 morning.

An alternate aircraft AI 1681 BOM-COK from Mumbai landed at 0433 hours today with 180 passengers. The rest of the passengers will arrive on an Air India flight at 0730 hrs.

In an incident of technical malfunction, the windshield of a Go First flight between Delhi and Guwahati cracked mid-air due to bad weather on Wednesday, July 20. The aircraft was diverted to Jaipur and landed safely.

Earlier this month, DGCA said that 30 such incidents take place daily, but these occurrences hardly have any safety implications. "On average, about 30 incidents do take place, including go-around, missed approaches, diversion, medical emergencies, weather, technical and bird hits," the top DGCA told ANI.

"Most of them have no safety implications. On the contrary, they are a sine qua non of a robust safety management system," he added.

In similar incidents, another two Go First flights were diverted due to engine snags. The DGCA has said that the matter is being investigated and the aircraft are being grounded. The DGCA added that the flights will take off once they get clearance from the authority.

Earlier on July 17, an Air India Express aircraft while operating from Calicut to Dubai was diverted to Muscat after a burning smell was observed from one of the vents in the forward galley of the flight.

Meanwhile, after frequent engineering-related glitches were reported in several airlines, the DGCA conducted several spot checks and advised that all aircraft at base and transit stations shall be released by certifying staff holding a licence with appropriate authorization by their organization.

F-16 Viper: The Most Sold Fighter

Girishlingana

21 Jul 2022

According to open sources, Lockheed Martin, the largest US maker, had announced the launch of a new F-16 Fighting Falcon fighter production line in Greenville, South Carolina.

While the fighters created at the same time have been decommissioned and have ceased, the US has recently continued to grow the plant that produces this fighter line, making the F-16 the most successful 4th generation fighter of the US.

F-16 Fighting Falcon | MOTORIZADO

One of the most popular and combat-tested ever to fly is the F-16 Fighting Falcon. F-16s currently used by militaries worldwide have flown more than 400,000 combat missions and accumulated 19 hours of flight time. A total of 25 militaries still use F-16s in their air services, and about 3,000 Fighting Falcons are in use.

Last Man Standing: F-16s Outlast Any Other Fighter Created Introduced at the Same Time

The United States Air Force flies more F-16s than any other type as part of its fighter fleet. The F-16's durability can be attributed to both its dependability and combat prowess as well as to its impressive cost-effectiveness, with the Falcon coming in at a significantly lower price compared to its larger fourth-generation, the F-15.

Due to its successful track record, the F-16 has continued operating despite the development of a more advanced fifth-generation stealth fighter. The F-16 is currently undergoing upgrades that will allow it to continue to be competitive in the air for years to come to guarantee that this is still the case. The newest generation of F-16s, known as the F-16V or "Viper," is incorporating several technologies that will further improve the F-16s combat capabilities, moving beyond the C/D variants of the aircraft to become the standard in many air forces around the world.

The F-16V also referred to as the F-16E/F Block 70/72, is the model that is currently being used. The F-16V warplanes can compete with the top-tier Russian heavyweight fighter Su-35 thanks to their AN/APG-83 AESA active phased array, Sniper ATP package, and AIM-9X missiles.

Eyes of the Tiger: F-16 AESA Radar

Active phased array radar is often only seen on fifth-generation aircraft due to its and high cost. The US chose to reduce them to the 4th and 5th generation fighters, indicating that they will stick around to support the 5th generation fighters for a slightly extended period.

The active phased array radar undoubtedly provides the fighter with a new edge, and many experts think that the F-16V may compete in some ways with the Russian Su-35, which only has a semi-active phased array radar.

The F-16V can acquire the air-to-air and air-to-ground combat skills of fifth-generation fighters thanks to the APG-83 fire control radar system. The engine on the F-16V has also been modified for higher performance while being more fuel-efficient, in addition to the extensively modernized avionics. The integrated fuel tank on the back of the F-16V allows it to have a substantially longer combat range than earlier models.

Price is Right: Why F-16 is the Darling of the Beholder and Death Sentence for the Enemy

The super jet Mig-25 Foxbat was initially intended to be fought by the F-15. But it turned out that the Mig-25 was entirely different from what the Pentagon had first believed. Thus, the original goal and motivation behind the F-15 vanished. The F-15 was being redefined by the Pentagon and forced into uses that its price did not support. The engines were detuned of the F-15 were detuned to extend its lifespan. This is the rationale behind the creation of the F-16.

Mig-25 Foxbat | Representative | The National Interest

Each F-15 variant outperforms the F-16 in its respective role on a technical level. At 1.5 times the price, the F-15c is a competent fighter and slightly superior to an F-16 in a fight. Even though it costs five times as much, the F-15E is a superior strike aircraft to an F-16. But you get the idea. The specialized F-15s can carry out some missions that the F-16 cannot. The F-16 is a low-cost, incredibly adaptable aircraft.

The F-16 is affordable and competent across the board. For the same money as one F-22, the Pentagon could purchase seven F-16s. Each F-16 costs $18.8 million, and an operational flight hour costs $7,000 per aircraft. The price of a single F-22 is $150 million, and a flight hour of use costs $64,000. A PMP, or Periodic Maintenance Procedure, is required for the F-22 every month.

F-16s have successfully completed nine sorties a day. Only capable of one sortie every three days, the F-22 is also extremely expensive to operate. In a war lasting more than a day, the F-22 is only occasionally usable, and in a conflict lasting more than a month, it is entirely useless.

The F-16's introduction, in my memory, left everyone in awe. It was incredibly effective at everything and was cheap, adaptable, stealthy, and stealthy. The performance of some much more expensive planes was matched or even surpassed it in some areas. It was, in my opinion, the first fly-by-wire jet that the United States had on hand.

Boom Supersonic unveils updated "Overture" supersonic airliner design

Prashant-prabhakar

21 Jul 2022

Set to begin production in 2024, the aviation company Boom Supersonic has unveiled updates to highly anticipated ultra fast "Overture" at the Farnborough International Airshow on July 19.

International Flight Network

After almost seven years in development, the supersonic airliner, which is expected to go from Seattle to Tokyo in less than 5 hours, is now one step closer to reality.

Already designed to cross the speed of sound, Boom has now decreased the Overture's passenger capacity, increased its number of engines and reconfigured the fuselage and gull wings in order to create a more efficient and "quiet" aircraft.

The aircraft is now designed for manufacturability and for maintenance. The tail-mounted engine in the old design would have been difficult to reach and maintain. Everything we've been saying for the last few years about fuel efficiency about the airplanes remains trueBoom founder and CEO Blake Scholl told Fast Company on Tuesday

Blake Scholl | World Biz Magazine

According to BOOM, the aircraft will now feature four smaller wing mounted engines, which will decrease the operational costs and allow it to fly quieter. Additionally, these engines will enable the Overture to soar at Mach 1.7 or about 1,300 miles per hour over water-faster than the speed of sound.

Key features:

Four-engine design: Overture will be powered by four powerful, wing-mounted engines that enable the airliner to cruise at Mach 1.7 over water and just under Mach 1 over land. Additionally, the four-engine design reduces noise while also decreasing costs for airline operators.

Executive Traveller

Quieter operation:  On take-off, Overture will use the world’s first automated noise reduction system. The airliner will fly without afterburners, meeting the same strict regulatory noise levels as the latest subsonic airplanes.

Representative | Aerospace Testing International

Contoured fuselage: Boom has applied the "principle of area-ruling" design technique to minimize drag and maximize fuel efficiency at supersonic speeds. Therefore, the Overture’s fuselage now has a larger diameter toward the front of the aircraft and a smaller diameter toward the rear.

Drivespark

Net zero carbon: Sustainability is woven into all aspects of Overture, from design and production to flight and end-of-life recycling.

Most of the Overture will be built using carbon fiber composites hence the aircraft will be lighter and therefore more fuel efficient.

Radhika Bansal

21 Jul 2022

A Go First flight, heading from Delhi to Guwahati, was diverted to Jaipur after the A320neo plane's windshield cracked mid-air.

The incident took place when flight G8 151, that took off from the Indira Gandhi International (IGI) Airport at 12:40 PM, was flying over Rajasthan. An official at the IGI airport said that though the pilots wanted to return to Delhi, they had to fly to Jaipur due to heavy rain and bad weather in the national capital.

This is the third incident of a technical glitch on a Go First aircraft in two days. A DGCA official said that the flight was diverted to Jaipur as the weather in Delhi was not appropriate. In a statement, Go First acknowledged that a windshield crack in the Delhi-Guwahati flight.

"The Pilot in Command was a very well-experienced pilot and a qualified TRI and handled the issue quite diligently and with maturity and due to the weather in Delhi he took a precautionary measure and diverted the aircraft to Jaipur. The passengers are being accommodated on the alternate aircraft from Jaipur to Guwahati and due care is being taken for their comfort and convenience."Go First

Earlier, on Tuesday, July 19, Go First's two Mumbai-Leh and Srinagar-Delhi flights faced technical glitches and both planes were grounded by the aviation regulator.

Go First A320 aircraft VT-WGA flight from Mumbai to Leh was diverted to Delhi due to Engine No.2 EIU (Engine Interface Unit) fault.

Meanwhile, another flight, Go Air A320 aircraft VT-WJG flight G8-6202, from Srinagar to Delhi was diverted to Srinagar due to Engine no. 2 EGT overlimit. Officials said that the DGCA was investigating the incidents and both the planes involved in engine snag incidents.

Earlier July 19, Go First's two Mumbai-Leh and Srinagar-Delhi flights faced technical glitches and both planes were grounded by the aviation regulator.

Scores of flights have been diverted owing to multiple technical snags in Indian carriers' aircraft during the last couple of days. Sources said that Civil Aviation Minister Jyotiraditya Scindia on Monday, July 18 told each airline to take all necessary steps that are needed to ramp up safety oversight.

The DGCA has now mandated that all flights need to be released by certified staff having an AME Category B1/B2 license and is currently investigating all incidents of technical malfunction.

DGCA asks airlines to depute aircraft engineers at all airports

Jinen Gada

21 Jul 2022

The Directorate General of Civil Aviation (DGCA) has ordered airlines to ensure qualified engineers are present at all airports to clear flights before departure after it discovered that technical glitches were being incorrectly identified and reported and airlines were relying heavily on junior engineers.

It ordered airlines to depute enough upkeep engineers in any respect airports to certify the airworthiness of planes earlier than departure. Airlines have been requested to adjust to the identical by July 28.

The DGCA said that it has also noticed that airlines were frequently seeking relief from the mandatory requirement that all equipment on aircraft be operative.

The civil aviation regulator issued the instructions following frequent situations of snags and comes within the backdrop of current mass protests by technicians. Civil Aviation Minister Jyotiraditya Scindia, too, held conferences with officers of airlines and DGCA and directions got to tighten security measures.

Spot inspections have been carried out by the DGCA at varied airports. These revealed that the reason behind defects was not being correctly recognized. Non-availability of sufficient licensed workers was one other concern. It additionally discovered that airways are giving a frequent one-off authorisation to sure junior engineers, which isn’t as per laws

The latest order follows a meeting held by Minister for Civil Aviation Jyotiraditya Scindia on aviation safety issues following incidents on IndiGo, Air India Express, Vistara and SpiceJet.

DGCA order comes after it found airlines were wrongly identifying aircraft defects

DGCA had already served a show-cause notice earlier this month on SpiceJet. The minister has sought to step up safety oversight on airlines.

“All aircraft base and transit stations shall be released by certifying staff holding AME [Aircraft Maintenance Engineer] Category B1/ B2 licence with appropriate authorisation by their organisation,” the DGCA order says. It adds that airlines may either position AMEs at base and transit stations or fly them to smaller stations as staff-on-duty.

AMEs are authorised to clear aircraft before every departure and upon rectification of technical problems by issuing a certificate for service release. B1 category of AMEs carries out mechanical engineering works involving airframe and engine and B2 category engineers carry out work related to avionics like electrical elements, radio and navigation.

The DGCA has said that in the absence of AMEs, airlines have been frequently granting one-off authorisation to junior-level engineers and that this practice is against regulatory provisions.

An airline official said on the condition of anonymity that the DGCA’s order will impose a burden on all airlines and they will now have to depute AMEs across their network, and may even be required to hire more AMEs.

Key to TATA’s strategy to infuse fresh energy into Air India

Jinen Gada

21 Jul 2022

The voluntary retirement scheme (VRS) scheme floated by the new management soon after Tatas returned to the helm of Air India has found an estimated 4,500 takers.

The airline rolled out a voluntary retirement scheme (VRS) in June this year for some permanent employees including cabin crew for the first time. These employees, as per VRS guidelines, must be above 55 years of age or have completed two decades of service.

The new management is in talks to purchase several new aircraft.

Air India had about 13,000 employees, of which 8,000 were permanent staff and the rest contractual.

Under Air India's VRS rules, people older than 40 and 20 years of continuous employment can opt for voluntary retirement. The company also gave an ex-gratia amount of Rs 1 lakh to those who opted for the VRS between June 1 and July 31.

Tata executives said Air India needed talent with the right attitude and aptitude to compete with international rivals. Air India announced the VRS for permanent employees of Air India in June and relaxed the age eligibility criteria to 40 from 55. In addition, the company announced an ex-gratia amount for employees who apply for voluntary retirement between June 1, 2022, and Jul 31, 2022.

"We are right-sizing the organisation, roping in new talent, apart from upgrading the quality of aircraft and all this needs talent with the right skills and abilities to build a superior airline, it is work in progress and needs patience as we do that."Tata Executive.

Tata Groups’s strategy is to infuse fresh energy by hiring new talent across operations in the airline. As part of its cost-saving measures, it's working on revamping the airline, improving productivity and revitalising archaic systems with digital culture, the daily report.

Tata Group is infusing fresh energy by hiring new talent across operations in the airline.

The Indian carrier is reportedly considering purchasing Boeing’s narrow-body planes alongside Airbus A350 jets as part of fleet renewal. Additionally, fleet upgradation, more destinations, world-class hospitality inflight or on the ground and many such areas are being worked upon.

Air India has been appointing new hires as well as taking on senior talent from group companies such as Tata Consultancy Services (TCS) and Tata Digital to handle customer experience, ground handling, the website, call centres and several other digital initiatives. Execution, design and customer service are also being reworked.
