C-17 vs C-130 A Comparison of two Legends Military cargo planes.

C-17 vs C-130 A Comparison of two Legends Military cargo planes.

In this article, the C130j Hercules freight plane and the C17 Globemaster passenger aircraft will be compared.

C-17 Globemaster 

Boeing C-17 Globemaster III is a large military transport aircraft that was developed for the United States Air Force (USAF). On 15 September 1991, the first C-17 performed its maiden flight and formally entered USAF service on 17 January 1995.

The size of the C-17 Globemaster III is measured to be 174 feet in length, 55 feet in height, and a wingspan of nearly 169 feet and 10 inches.

The C-17 is known for being the most adaptable cargo aircraft in the USAF’s service, and its main task is to strategically deliver both cargo and troops to all of the country’s operational sites.

For its tactical airlifting and airdropping duties, the aircraft is most known. Additionally, it has the capacity to carry numerous ambulatory patients during medical evacuation operations.

When compared to the C-5 Super Galaxy, the largest freight transport aircraft used by the US Army, neither the C-17 nor the C-130 can compete.

Four Pratt & Whitney F117-PW-100 turbofan engines, based on the Pratt & Whitney PW2040 commercial engine used to power the Boeing 757, are utilized to propel the C-17.

C- 130 Hercules

The Lockheed C-130 Hercules is a four-engine turboprop military transport aircraft made in the United States by Lockheed Martin. In 1956, the C-130 was entered into service by the United States. The C-130E, C-130H, and C-130J are the current versions of the C-130 that are still in use.

With a length of 97 feet and 9 inches, a height of 38 feet and 10 inches, and a wingspan of over 132 feet and 7 inches, all of these variations are essentially the same in size.

Regarding the C-130, its tactical airlifting duty is its primary focus, and it can fly from a dirt runway to carry both supplies and troops into difficult terrain.

It performs several of the following additional mission functions as well, including airlift assistance, aeromedical missions, weather reconnaissance, aerial firefighting for the U.S. Forest Service, and natural disaster relief.

The C-130 is propelled by four Allison T56-A-11 or -9 turboprop engines, based on the same engines that were used in the C-130A, the first version of the aircraft.

The Rolls-Royce AE2100D3 turboprop engine, which was installed in the penultimate type C-130J, improved the aircraft’s overall performance in comparison to all earlier variations.

B737 MAX 8 Cabin System Malfunctions: Passengers Experience Nosebleeds and Ear Pain

B737 MAX 8 Cabin System Malfunctions: Passengers Experience Nosebleeds and Ear Pain

A Boeing 737 MAX 8 jet operated by Korean Air, bound for Taichung, Taiwan, encountered a distressing incident when its cabin pressurization system malfunctioned shortly after takeoff.

Reports from passengers described a sudden onset of problems, prompting the aircraft to promptly return to Incheon International Airport in Seoul, South Korea. As the malfunction unfolded, the aircraft was compelled to rapidly descend from its cruising altitude of over 30,000 feet to approximately 9,000 feet.

2 passengers suffered nosebleeds; 15 reported ear pain

This sudden change in altitude caused discomfort among passengers, with at least two individuals suffering from nosebleeds and 15 others experiencing ear pain and hyperventilation. Emergency protocols were swiftly activated, including the deployment of oxygen masks as the aircraft descended.

Passengers recounted harrowing moments during the incident, describing how the aircraft unexpectedly lowered altitude during meal service, leading to cries from children and widespread discomfort among travelers. Many reported sensations of ear pain, dizziness, and the disorienting effects of sudden cabin pressure changes.

Despite the chaotic situation, the cabin crew was commended for their prompt response, assisting passengers with oxygen masks and swiftly securing the cabin for landing. The pilots successfully landed the aircraft back at Incheon International Airport, ensuring the safety of all on board by 7:38 p.m. local time.

No serious injuries reported despite the alarming incident

Following the incident, Korean Air took immediate steps to mitigate disruption, arranging for a different aircraft to complete the flight to Taichung the following morning. The airline issued an apology to affected passengers and initiated an investigation into the root cause of the malfunction.

Videos shared by Taiwanese passengers captured the tense atmosphere inside the cabin during the incident, highlighting the urgency and gravity of the situation faced by those on board.

How Emirates pilots reduce fuel and emissions during operations

How Emirates pilots reduce fuel and emissions during operations

Flying smarter and minimizing fuel consumption and emissions starts in the cockpit. Emirates embarked on implementing “Green Operating Procedures” (‘Green Ops’) in 2016, adopting a multi-pronged approach to reduce on-ground and in-flight fuel use.

This initiative also provides pilots with necessary education, awareness, data analytics, and technology to manage flights efficiently.

Led by an internal cross-functional Operations Efficiency Steering Group, Emirates aims to mitigate unnecessary fuel burn and emissions while maintaining high safety standards.

In the financial year 2023-2024, ‘Green Ops’ and other initiatives helped reduce fuel burn by over 48,000 tonnes and carbon emissions by more than 151,000 tonnes. Key operational measures include:

Discretionary Extra Fuel

  • Pilots assess operational circumstances to uplift extra fuel beyond the minimum regulatory standards only when necessary, resulting in a significant reduction of discretionary extra fuel uplift.

Flight Speed Optimization

  • Pilots optimize flight speed to reduce fuel consumption while maintaining schedule integrity, as part of Emirates’ standard operating procedures.

Reduced Flap Landing

  • Pilots select flap settings that minimize aerodynamic drag, reducing fuel consumption without compromising safety.

Idle Reverse Thrust

  • Upon landing, pilots use idle reverse thrust to decelerate the aircraft, depending on runway conditions, to reduce fuel consumption.

Reduced Engine Taxi-In (RETI)

  • After landing, pilots shut down one or two engines during ground taxiing, increasing the use of RETI sevenfold since its introduction.

Optimized Flight Routings

  • Emirates uses flexible flight routes, optimizing each route for fuel efficiency and time savings since 2003.

Technology and Innovation – FlightPulse

  • Emirates introduced FlightPulse, a self-service data analytics tool developed with GE Digital Aviation Services, enhancing monitoring and collaboration for improved safety and fuel efficiency.

Center of Gravity Optimization

  • Aircraft are loaded to optimize the center of gravity, enhancing aerodynamic efficiency and saving fuel.

APU Usage

  • On the ground, Emirates reduces APU usage in favor of electrical ground power units (GPU), reducing emissions by over 30%.

Adjusted Potable Water Uplift

  • Flights upload the required amount of potable water calculated scientifically, reducing weight and ensuring fuel efficiency without compromising passenger comfort.

Through these comprehensive measures, Emirates pilots play a crucial role in reducing fuel consumption and emissions, contributing to more sustainable airline operations.

Air India Alters Elderly Couple’s US Flights Without Notice

Air India Alters Elderly Couple's US Flights Without Notice

An elderly couple’s travel plans were unexpectedly disrupted when Air India allegedly changed their tickets and destinations without prior notification, as reported by a user recounting the ordeal.

According to Dushyant Arora, the couple discovered the changes only when they attempted to check in for their flight to Newark, New Jersey, scheduled for June 19.

They were shocked to find that Air India had booked them on separate flights. The husband was re-routed to New York instead of Newark, departing on a different day than originally planned, while the wife’s itinerary remained unchanged.

The couple, unfamiliar with the changes and concerned about flying separately, decided to cancel their tickets. This decision was particularly difficult for the mother, as it would have been her first time flying abroad, and she expressed reluctance to travel alone.

The couple was not contacted by anyone from the airline to inform them of the changes. The tickets had to be cancelled by the couple. In response to the X user, Air India stated that the customer’s request for a complete refund has been fulfilled.

“Dear Sir, we apologise that this happened and assure you that we never plan to interfere with our clients’ travel arrangements. “We have conducted a complete refund in accordance with the primary customer’s request, who was booked in the PNR,” stated Air India.
