10 things you must know about Airbus A-380

Why A380 aircraft have become so important to many airlines today

1. Easy on the Gas

It’s big, but not a gas-guzzler. Calculated per passenger, Lufthansa’s A380s get 69 miles per gallon. The airplane holds 81,890 gallons, meaning that more than a third of what the plane weighs on takeoff—560 tons—is the weight of the fuel.

2. Rolls-Royce Engines

The four Rolls-Royce engines of the A380 are the length of a Mercedes C-series sedan and four times as heavy. The internal temperature of the engine in operation is 3100 fahrenheit degrees.

3. Big Wings

The A380’s wings are the biggest ever created, 2,775 square feet in size and fully 54 percent larger than the wings of a Boeing 747.

4. Smooth Takeoff

During takeoff, the A380’s wings practically flap, as the tips flex upwards as much as 13 feet.

5. European Made

The A380 is a pan-European product. The engines and wings are produced in England, parts of the fuselage and the tail in Germany and Spain. Airbus test engineer Fernando Alonso describes the airplane as “a symbol of Europe.” When complete, these airplane sections are shipped by land, air, and sea for final assembly in France.

6. Exclusive Airports

Twenty airports in the world are handling A380 service, meaning that they have long enough runways, wide enough taxiways, and 78,000 square feet available at the boarding gate where the plane can be parked. Airports also need special equipment to handle passengers and cargo, and sometimes even baggage conveyor belts must be lengthened since 500 to 800 passengers means a lot of luggage.

7. More Computer than Machine

The A380 is flown by two pilots. “Actually, there’s no difference between flying 30 passengers and 526,” says Harald Tschira, a Lufthansa first officer. “This airplane is very easy to control, despite its weight, and the handling characteristics are more like a short-range airplane.” The pilots can nap in a sleeping compartment located behind the cockpit on long-haul flights while a second crew provides backup.

8. 21 Attendants

Twenty-one flight attendants are assigned to the Lufthansa A380, working in five galleys and using a separate computer system dedicated to cabin activities. They have their own rest compartment with eight beds located below the galley at the rear of the airplane.

9. Seat with a View

From individual video monitors at each seat, passengers can watch the progress of the flight from cameras mounted below the cabin and on the airplane’s tail.

10. Maximum Range

The A380-800 has a design range of 8,500 nautical miles (15,700 km), sufficient to fly nonstop from Dallas to Sydney, and a cruising speed of Mach 0.85 (about 900 km/h, 560 mph or 490 kn at cruising altitude).

The LCA Tejas Aircraft Crash: Understanding the Reasons – Air Marshal GS Bedi’s Perspective

The LCA Tejas Aircraft Crash: Understanding the Reasons - Air Marshal GS Bedi's Perspective

Air Marshal GS Bedi, a renowned fighter jet pilot and experienced crew member, recently participated in a YouTube interview with Def Talks hosted by Aadi. During the interview, he provided insights into the recent Tejas aircraft crash in Rajasthan, which marks one of the first crashes involving an aircraft from the Tejas family since its production commenced 20 years ago.

Numerous questions have emerged regarding the circumstances surrounding the Tejas aircraft crash and the potential causes of failure. Air Marshal Bedi adeptly addressed these concerns by outlining possible scenarios that could have led to the crash. His expertise shed light on the complexities involved in such incidents and provided valuable perspective on the aviation community’s understanding of the event.

At the outset, Tejas lacked a simulator and a trainer aircraft for initial training. However, pilots were provided with simulation trials before flying the Tejas aircraft. Initial reviews indicated stability during flight, with the aircraft maintaining a straight glide. However, there was an incident where the aircraft experienced an engine malfunction, prompting the pilot to eject safely.

Pilot Safe Ejections

The decision to eject was made as a precautionary measure, considering the aircraft’s low altitude and steep descent angle. With the aircraft’s altitude dropping rapidly, attempting to balance and land it was deemed too risky. Ejecting ensured the pilot’s safety, as deploying a parachute at such low altitudes could have been disastrous.

He chose to eject to ensure a safer distance from the ground. The aircraft is at an angle of less than 3 degrees during the approach. At a height of 100 meters, the aircraft is nearly 20 times its length away from the ground. This means the touchdown point will be approximately 4 kilometers ahead.

However, as the altitude decreases, the approach becomes too short due to the rapid descent rate. Consequently, the pilot opts to eject rather than attempt to stabilize the aircraft for a ground landing. If he had not ejected, there’s a high probability that his parachute would have deployed at that low altitude.

LCA Tejas engine Issue

Investigations revealed the engine malfunction was likely due to lubrication issues or other technical faults. Such split-second decisions underscore the potentially catastrophic outcomes that can result from technical failures.

The pilot involved was highly experienced and well-trained for airshow displays, suggesting timely decision-making. Nevertheless, accidents can stem from technical glitches, human errors, or unforeseen circumstances like bird strikes.

Air Marshal Bedi emphasized the importance of pilots being trained for emergency situations, including ejecting from the aircraft when control is lost. Despite advancements in technology, technical issues remain unpredictable, necessitating ongoing learning and improvements in aircraft systems.

Today, the Tejas mk1A aircraft completed its inaugural flight at the Bangalore station, marking the dawn of a new, advanced version of the Tejas aircraft. This iteration boasts enhanced avionics and improved aircraft structure.

Observing the helicopter in flight, it shares design elements with the Harbin Z-10, notably in the front fuselage and cockpit canopy. The wing stubs for weapon mounts exhibit similar shapes, though with less pronounced angular features. With a tandem seating arrangement, the Z-21 also draws comparisons to the Mil Mi-28, featuring an elongated body with five rotor blades and weapon bays on its sides.

The unveiling of the Z-21 has triggered speculation about its potential role in future military operations. Analysts suggest that beyond its firepower, its introduction could signal significant technological advancements. There’s particular interest in whether China will incorporate a ‘manned-unmanned teaming’ system akin to later Apache models, enabling the Z-21 to control armed drones for reconnaissance and attacks, reducing risks to the helicopter itself.

Qantas Airbus A330 Makes Safe Landing After Engine Blowout

Woman spends tortuous three months trying to resolve huge Qantas errors

A Qantas Airbus A330 Aircraft, flight number QF781, has landed safely without incident in
Perth after the passengers on the Perth-bound flight reported hearing a ‘loud bang’ from one
side of the twin-engined plane engine. The Airbus A330 aircraft made a priority landing at
Perth Airport around 9:37pm local time on 25 March, arriving approximately 52 minutes
behind schedule.


Upon landing, emergency services met with the aircraft on the tarmac. However, the aircraft
taxied to the gate without assistance, with the passengers disembarking normally.
The ‘loud bang’ heard by passengers happened due to a mid-air engine blowout, therefore
resulting in the pilots having to manually shut off the affected engine, together with
requesting a priority landing into Perth Airport. Qantas also added in a statement that the
Airbus A330 aircraft was designed to operate with one engine too.

Qantas QF781 is a daily scheduled flight from Melbourne to Perth, utilising the Airbus A330
on the route. The Aircraft in question is VH-EBA, an approximately 21 years aircraft,
equipped with 2 GE CF6 engines according to airfleets.net. The Airbus A330 have been a
frequent regional workhorse in Qantas’ fleet, connecting major australian cities with major
destinations within Asia. the Airbus A330 is also used on high-density domestic routes,
similar to QF781, from Melbourne to Perth.

Engine Issues – Should you be concerned?


While engine issues are highly uncommon due to the stringent checks and quality control on
each component within the engine, there might still be exceptional occasions where such
incidents happen. However, while recognising the risks of dual engines, Aircraft
Manufacturers and Organisations have actually came up with standards so as to ensure that
an aircraft can also land on a single engine, similar to what we saw on QF781.


One of the most well known standard is Extended-range Twin-engine Operations
Performance Standards (ETOPS) which is an acronym for twin-engine operation in an
airspace further than one hour from a diversion airport at a designated one engine
inoperable speed. This ensures that twin-engined aircraft could safely operate routes over
water or remote land without an alternative airport near the flight path, which once required
aircraft with 3 or 4 engines to fly on that route.

In this case, the Airbus A330 has been certified to fly ‘Beyond ETOPS 180’, and have
received ETOPS 240 certification, which is a certification to enable the twin-engined aircraft
to fly for up to a maximum of 240 minutes with 1 engine inoperative in a cruise condition.
Currently, most twin-engined widebody aircraft in operation would generally have an ETOPS
certification of at least ETOPS 180, with the new Airbus A321LR also having ETOPS 180
certification, therefore enabling the narrowbody to fly long haul flights.
