Pilot unions at Air India on Sunday, December 31 expressed "concern" over the Tata Group-owned airline's alleged threat to the cockpit staff with "appropriate measures" if pilots report sick for duty.

In a communication to Air India senior vice president for flight operations Manish Uppal on Sunday, December 31, the Indian Pilots Guild (IPG) and Indian Commercial Pilots Association (ICPA) said that reporting illnesses without the "fear of reprisal" is in the interest of flight safety. IPG is the wide-body aircraft pilots' body at Air India while ICPA represents pilots who fly the full-service carrier’s narrow-body Airbus 320 family aircraft.

The copies of the letter have also been marked to Air India Chairman N Chandrasekaran, DGCA Vikram Dev Dutt, Air India Managing Director and CEO Campbell Wilson, among others.

"We are writing to express our concern and objection regarding recent communications implying threats of appropriate measures for sick reporting," the pilot bodies said in the communication. The two unions stated that the IPG-ICPA understand the importance of maintaining a productive and efficient work environment.

They said, "It is crucial to acknowledge the significance of pilot's health and its cascading effect on flight safety." There may be instances where pilots feel "intimidated" or "compelled" to operate flights despite their health concerns, potentially jeopardising the safety of the flight, the letter warned. "Threatening employees for reporting sickness not only violates ethical principles but also goes against the Aircraft Rules Act, 1937," they said in the communication.

The DGCA places a high priority on safety, the physical and mental health of pilots of utmost importance, the letter stated, adding, “pilots should feel comfortable reporting illnesses without the fear of reprisal in the interest of flight safety.”

Unions Not Happy with the Management

Air India pilot unions IPG and ICPA on Saturday, December 2 expressed "deep concern" over the flight duty and rest period scheme adopted by the Tata Group airline, accusing the carrier of deviating from the DGCA-approved norms.

The two unions -- Indian Pilots' Guild (IPG) and Indian Commercial Pilots' Association (ICPA) -- in a joint communication to the Directorate General of Civil Aviation also alleged that the introduction of a side policy, along with the flight duty

The pilot unions have also sought a review and assessment of the issue by the DGCA, requesting it to take appropriate measures to address the matter. Pilots and cabin crew's flight duty time limitations are governed by the aviation safety regulator DGCA, which proposed more rest hours for the pilots last month.

In recent months, the issue of fatigue has been in focus, especially after the death of an IndiGo pilot, who had collapsed at the boarding gate of Nagpur airport in September. And last month, an Air India pilot during a training session showed signs of discomfort and later died at the Delhi airport.

However, Air India said the pilot was not on active flying duty and was undergoing conversion training to operate wide-body aircraft.

The pilot unions are urging the DGCA to conduct a thorough review and assessment of Air India's new policy, emphasizing the importance of ensuring that airline practices are in line with DGCA regulations. The letter highlights the need for compliance with safety norms to protect both crew members and passengers, stressing that any deviation from approved regulations could jeopardize overall safety and well-being in the aviation sector. The situation reflects a broader concern about the balance between operational efficiency and safety in the rapidly evolving Indian aviation industry.

Can Commercial Planes Venture Beyond Earth’s Atmosphere?

Abhishek Nayar

01 Jan 2024

As we sit comfortably in our commercial airplanes, cruising at 35,000 feet and marveling at the wonders of modern aviation, a question may cross our minds: Can these airplanes venture into space, even by mistake? In this article, we explore the scientific and engineering limitations that prevent commercial airplanes from reaching the vast expanse beyond Earth's atmosphere.

Aerodynamic Lift: Beyond the Karman Line

A fundamental aspect of flight is aerodynamic lift, generated by an aircraft's wings exploiting pressure differences with air molecules. However, in space, characterized by a lack of air molecules, wings are rendered ineffective, and no lift is created. This limitation sets a clear boundary known as the Karman Line, approximately 62 miles (100 km) above sea level, beyond which space begins.

As commercial airplanes ascend, the air density decreases, affecting lift generation. Most airplanes have a service ceiling between 38,000 and 41,000 feet, and attempting to climb beyond this results in a lack of sufficient air density to support lift.

Combustion and Thrust in the Void

The combustion engines of commercial airplanes, reliant on oxygen in the atmosphere, face significant challenges as altitude increases. Above 45,000 feet, where air density diminishes, the engines struggle to draw in enough air for combustion, limiting thrust. Unlike rockets, which carry their own liquid oxygen, airplane engines rely on atmospheric oxygen, making them inefficient in the low-density conditions of space.

As engines climb, they reach RPM limits, and the lack of air density hinders their ability to produce the required thrust, ultimately restricting the altitude commercial airplanes can reach.

Cabin Pressurization: Breathing in the Stratosphere

Above 12,500 feet, air density becomes insufficient for the human body to survive without artificial pressurization. Commercial airplanes employ High-Efficiency Particulate Air (HEPA) filters and compressed air from the engines to pressurize the cabin. However, as airplanes approach the boundary of space, engines can no longer supply enough air to maintain cabin pressure. Without pressurization, passengers would face the risk of hypoxia, a deficiency of oxygen that can lead to organ impairment and death.

Control Surfaces in the Void: Maneuvering Challenges

The control surfaces of commercial airplanes, such as ailerons and rudders, rely on air density to function effectively. In the low-density environment near the Karman Line, these surfaces lose their efficiency. Flight tests near this boundary have shown that traditional control surfaces become nearly useless. To achieve maneuverability in space, a Reaction-Control System, commonly used in spacecraft, becomes essential.

Escape Velocity, Re-entry, and the Melting Point

The escape velocity required to break through Earth's atmosphere is far beyond the capabilities of commercial airplanes. Even if a plane could achieve such speeds, the subsequent re-entry would subject it to temperatures exceeding the melting point of its aluminum airframe. The space shuttle faced temperatures of up to 1650°C during re-entry, while aluminum melts at 660°C.

To survive re-entry, an airplane would need a heat-resistant system, such as silica tiles, but this would increase the aircraft's weight, reducing its payload and making space travel economically unfeasible for commercial purposes.

Conclusion

While commercial airplanes have revolutionized global travel, their design and capabilities are inherently grounded in Earth's atmosphere. The transition into space requires technologies and engineering beyond the scope of conventional aviation. As we gaze out of airplane windows at cruising altitudes, we can appreciate the remarkable achievements of aviation while recognizing the boundaries that separate us from the cosmos.

29 Dec 2023

Aegean Airlines will wet-lease two A320-200s from Cyprus Airways under a long-term ACMI deal covering all of 2024. The first aircraft began operating for the Greek airline on December 19, 2023.

5B-DDQ (msn 4055) was ferried from Larnaca to Thessaloniki on December 18 and operated its first flight for Aegean Airlines to Prague Václav Havel the next day, Flightradar24 ADS-B data shows. The second aircraft, 5B-DDR (MSN 3933), will begin operating for the Greek airline in March 2024.

Besides the two A320-200s, Cyprus Airways also operates two A220-300s. The airline is planning to add more A220, considering the type as the foundation of its future fleet. The airline operates in a highly seasonal market that has been heavily affected by the drop in demand from/to Israel due to the war in Gaza, as Israel is a key international market for Cyprus.

Under the terms of the wet lease agreement, Cyprus Airways will also provide pilots and cabin crews to operate the leased aircraft, the first of which is due to be delivered to Aegean in December 2023.  The second aircraft will follow in March 2024, before the busy summer season gets underway for the Athens-based carrier. The agreement was facilitated by aviation and ACMI specialists, Zela Aviation. 

Aegean has also recently been struggling to offset a capacity shortfall caused by the need to ground several of its Airbus A320neo aircraft over the next few months as a result of unscheduled checks that are required on Pratt & Whitney PW1100G engines. This is an ongoing issue that has affected a large number of airlines worldwide in recent months. 

"We are very happy and proud to take the next step in our strategic cooperation with Aegean. We already have an extensive codeshare agreement in place where we work closely to offer and optimise our joint products and services," Cyprus Airways' Chief Executive Paul Sies said.

Sies highlighted that Cyprus Airways routes to Dubai International Airport (DXB), Paris Charles De Gaulle International Airport (CDG), and Milan Malpensa Airport (MXP) performed better, helping the airline compensate for the loss of traffic to/from Israel.

In turn, Aegean Airlines operates twenty-eight A320-200s, sixteen A320-200Ns, five A321-200s, twelve A321-200NX, nine ATR72-600s, and a single DHC-8-100. The turboprops are placed on the AOC of Olympic Air. Besides its jet fleet, the carrier also operates a turboprop fleet of nine ATR72-600s. The turboprops are operated under the Air Operator Certificate (AOC) of Olympic Air. This wet-lease agreement signifies a significant development in Aegean Airlines’ operational capabilities, offering expanded service and efficiency.

Cyprus Airways is the latest incarnation of an airline using that name and has been operating as such since July 2016. The carrier operates an all-Airbus fleet comprising of two A220-300s delivered in 2023, plus two A320-200s registered 5B-DDQ and 5B-DDR. Cyprus Airways serves a highly seasonal market, which has recently faced challenges due to decreased demand from and to Israel, a crucial international market for Cyprus, primarily affected by the conflict in Gaza.
