FOREWORD

As an airline pilot and aviation author of many years, I have long been aware of the interest in aviation among the general public. Myriad books have been written on the subject, from enthusiast booklets to technical manuals, and from specialized military fighter publications to magazines on airliners, but few catch the interest of layman and professional alike. This book does.

Flying the A380 has been written by a senior A380 captain, whose first-hand knowledge of what it is actually like to fly the giant aircraft brings the subject alive. The reader can get a sense of being part of the crew and is introduced to the sophistication of the cockpit displays in a way that can be appreciated by all, whether interested layperson, enthusiast or aviation professional.

The A380 has a massive maximum take-off weight of 570,000kg (1,256,000lb) and can carry up to 850 economy-class passengers in a double-decker layout; from the planning stage, its enormous size fired the imagination of the public. Reports of on-board lounge bars and discos, and even swimming pools and gyms, stretched reality a little too far and ignored commercial pressures, never mind the weight of water and exercise equipment! In the main, airlines have adopted a maximum of about 470 passengers in a three-class layout that allows comfortable travel for all. First-class passengers are also able to enjoy small lounges, separate cabins and beds, and, in one configuration, fitted showers.

At every air show where an A380 is on display, large numbers of people gather to gaze in amazement at its vast bulk; whenever it took to the air during its development, huge crowds flocked to watch. Interest in the A380’s first flight drew 50,000 spectators, and seats on the inaugural commercial flight with Singapore Airlines, from Singapore to Sydney in October 2007, were auctioned on eBay. Such was the appeal of the historic occasion that a total of US$1.3 million was raised and donated by the airline to charities.

What is the giant A380 like to fly, however? What is the detail of the flight-deck presentation; what are the functions of the sophisticated cockpit displays; and how is the aircraft operated? Until now, such information has been the preserve of those few privileged professional pilots who have been given the chance to fly the huge machine. In Flying the A380, however, all have the opportunity to see the cockpit at close range and to experience a trip on the flight deck of this magnificent aeroplane.

INTRODUCTION

Before I started my conversion training for the Airbus A380 in early 2008, I began scouring the bookshops and Internet for a book that would tell me about the aircraft. As I had flown only American made Boeings previously, I expected that it would be a challenge to adapt to the concepts and intricacies of flying the European made A380, and I wanted an oversight of the aircraft’s operations and systems. I was unsuccessful, however, as all I found were a few books on the development of the aircraft. Presumably, this was due to the fact that it had been introduced into service only recently, in late 2007.

After my successful conversion to the aircraft, I decided to put right this lack of information by writing my own book on its operations and systems, to introduce both pilots and aviation enthusiasts alike to the A380. I have based the book on a typical flight from London to Dubai, and have explained the operations and different systems of the aircraft along the way. The story also covers the latest in airliner operations in terms of air traffic and cockpit management.

It is my hope that this book will provide a good overview of the operations and concepts of the newest and largest passenger aircraft in the world, the Airbus A380.

Captain Gib Vogel, February 2009

CHAPTER 1

PRE-FLIGHT

The flight crew pauses by the steps of the Airbus A380 before boarding and, as they glance up at the massive fuselage, they briefly contemplate the enormous size of the aircraft. With a wingspan of 79.8m (261.8ft), a height of 24.1m (79.1ft) and a length of 73.0m (239.5ft), it looks big and stubby on the apron. The Airbus A380 is 15m (49ft) wider and 2m (6.5ft) longer than the Boeing 747, and is the biggest commercial airliner in the world. It has an incredible maximum take-off weight of 570 tonnes (561imp/628US tons), compared to the 397 tonnes (391imp/438US tons) of the passenger-carrying 747-400, a maximum range of 8,200nm (15,200km) and a maximum altitude of 43,000ft.

FLIGHT PLANNING

Two or three hours before arriving at the aircraft, in a comfortable hotel room, the captain of this flight, Skybird 380 from London Heathrow to Dubai, would have logged on to the Internet to access the flight plan for perusal. Around four hours before scheduled departure, the flight planning department at the airline’s home base in Dubai would have chosen the most suitable routing and filed an Air Traffic Control (ATC) flight plan for the trip. This plan would also have been filed with the first en-route air traffic control centre, the Central Flow Management Unit (CFMU) at Eurocontrol, which, in turn, would have forwarded it by telex to the other air traffic centres along the route, in Romania, Turkey and Iran.

Route-search computer programs, such as Lufthansa’s ‘LIDO’, British Airways’ ‘STAR’ and Continental Airlines’ ‘Phoenix’, display the most cost-effective routes for nominated departure and arrival airports. Flight routing costs, such as fuel, aircraft time and air traffic control charges, are included for consideration, but excluded are variable costs, such as catering and amenities, staffing and landing fees. Fuel cost, however, is the overriding factor, and on long-haul flights it accounts for 90 per cent of total basic flight routing costs (75 per cent on short-haul flights). Essentially, air traffic control charges are time based – the longer the over-flight, the more the airline pays – and vary across Europe. For example, on the flight described in this book, the charge for over-flying the Slovak Republic was US$400, while crossing Romania cost US$1,700.

Winds aloft along the route are also an important factor in the calculations, as they affect flight time and, consequently, fuel burn. With the high cost of fuel, it is not surprising, therefore, that the shortest flight-time route is usually the best option. Having selected the most cost-effective routing, the dispatcher checks the en-route weather for significant forecasts and the relevant Notices to Airmen (NOTAMS) to verify the suitability of the routing. NOTAMS are published by national aviation authorities and list abnormal circumstances that may affect flight through their respective airspaces, alerting pilots to such situations as inoperative radio beacons, closed airport facilities and specific airspace closures for military exercises and similar activities.

Also collated by the dispatcher is information prepared by the airline’s traffic specialists on the expected load, including passenger and cargo distribution, and the aircraft serviceability status, which is provided by engineering central control. These items, plus the weather reports, NOTAMS and copies of the ATC flight plan, flight log and fuel log, form a flight planning briefing package that is uploaded to the Internet for pilot access. A copy of the package is also sent to the airline’s departure dispatch office, in this case in London.

In the airline’s London office, the local dispatcher confirms the availability of the selected route with Eurocontrol and checks the allocated take-off time, known as the ‘slot time’. To co-ordinate aircraft joining the busy airway system aloft, all flights departing European airports are allocated a slot time with which the pilots are required to comply. If the selected routing is unavailable, or if the allocated slot time creates an excessive departure delay, another suitable route would be requested from the Dubai dispatch office and a fresh flight plan filed. These ATC slot times are not to be confused with airport slot times, which are negotiated and traded by airlines months earlier to schedule their departures from this busy airport.

Weather is also checked by the captain, using terminal aerodrome forecasts (TAFs), which give forecasts for the coming twenty-four hours for all the required en-route, destination and alternate (diversion) airports. For this flight, the captain observes that no adverse weather is reported for the nighttime arrival at Dubai. The city’s weather is usually clear, but occasionally morning fog or sandstorms occur, and subsequently the low visibility can be a cause for concern. Dubai airport charts, produced by Jeppesen, form part of the Electronic Flight Bag (EFB) on the flight deck and give the minimum visibility required for the arrival.

The captain scans the NOTAMS for anything that could have an adverse effect on the flight. Information is presented for the entire route and can be extensive, but pilots become skilful at picking out notices of concern as they glance through the many pages, saving, perhaps, an hour of reading. Any notices concerning the departure, destination and alternate airports are scrutinized a little more carefully, however, while the remainder of the NOTAMS can be read in more detail during the cruise.

Fuel Requirement

When deciding the final fuel figure, factors such as possible delays resulting from busy traffic at arrival time, air traffic control procedures, or poor destination or en-route weather need to be considered and may require extra fuel to be carried. For example, delays can be expected when arriving at Heathrow during the peak evening period, thus justifying the carriage of additional fuel. Pilots are aware of the high cost of fuel, however, and endeavour not to uplift more than necessary. Taking additional fuel can be not only costly, but also wasteful, as on long flights it is expected that half the extra fuel will be burned just carrying that extra fuel. That is to say, for every extra 1,000kg of fuel loaded, 500kg will be burned off in carrying the extra weight on a long flight, leaving only 500kg for use at the destination.

To prevent airlines from taking too little fuel, however, aviation law dictates that a minimum amount must be carried for each flight. The minimum fuel load comprises:

Burn-Off – Fuel used for the flight.Contingency Fuel – Additional fuel to safeguard against unexpected circumstances, equal to 5 per cent of the burn-off (this may be reduced to 3 per cent if approved by the local authorities) plus sufficient fuel to reach a mandatory alternate airport.Reserve Fuel – For holding.Taxi Fuel.

The Zero Fuel Weight (ZFW) – the weight of the aircraft, crew, passengers, baggage and cargo, but without fuel – of the A380 for this particular flight is 355.0 tonnes (349.4imp/391.3US tons); the burn-off for the six-hour flight is 74.0 tonnes (72.8imp/81.6US tons); the fuel load for contingency, alternate and reserve is 14.9 tonnes (14.7imp/16.4US tons); and the taxi fuel is 1.5 tonnes (1.5imp/1.7US tons), giving a total minimum flight-plan fuel requirement for refuelling the aircraft of 90.4 tonnes (89.0imp/99.6US tons) and a total taxi weight of 445.4 tonnes (438.4imp/491.0US tons). The taxi weight minus the taxi fuel of 1.5 tonnes gives a take-off weight of 443.9 tonnes (436.9imp/489.3US tons), and the take-off weight minus the burn-off gives an expected landing weight of 369.9 tonnes (364.1imp/407.7US tons). The captain considers that the satisfactory weather forecast and other factors do not justify loading extra fuel, and he accepts the minimum flight-plan fuel required of 90.4 tonnes.

DATA TRANSFER

Having made the decision, the captain calls the London dispatch office to approve the planned routing and the requirement for flight-plan fuel. The approved flight plan and other briefing documents are datalinked to the aircraft’s EFB as an ‘e-folder’ (electronic folder) at least one hour before flight departure, allowing the crew to bypass the dispatch office on arrival at the airport and proceed directly to the aircraft. Before boarding, however, the pilots will need to collect a hard copy of the flight briefing package, and the captain will be required to initial a flight-plan summary that will be returned to the dispatch office. The hard copy of the briefing package is carried in case of EFB failure, and good airmanship dictates that the pilots keep a running log of progress, filling in the flight details on the paper flight log as the aircraft progresses along the route. Thus if the EFB does fail, the pilots can fall back on the updated manual flight log. On most flights, however, this practice becomes somewhat academic, as all the flight details are recorded electronically and the hard copy is simply discarded at the end of the trip.

Datalink messaging is used extensively for the transfer of data between the aircraft and ground units, and is sent and received via the on-board Aircraft Communications Addressing and Reporting System (ACARS). ACARS transmissions are sent via radio or by satellite communication (Satcom), allowing the easy transfer of data between the aircraft and airline operations, weather service providers and ATC centres.

CREW ARRIVAL

As the two cockpit crew travel on the bus to the airport, they take the opportunity to discuss the briefing they have both checked earlier on the Internet. On arrival, the bus takes them to an airside perimeter gate for the routine security screening process before driving them directly to the aircraft. By the time they arrive, about forty-five minutes remain before the scheduled departure of the Skybird 380 service from London to Dubai.

CHAPTER 2

BIRTH OF THE A380

The super jumbo was conceived in the mid-eighties, when the two big aircraft manufacturers, Airbus and Boeing, contemplated the need for a very large passenger aircraft. While European builder Airbus pursued the idea of an aircraft that could carry as many as 800 people, across the Atlantic, Boeing decided on another strategy. It set out to design smaller, but longer-range planes that would operate from point to point, betting on passenger preference for flying direct to cities of choice rather than to a hub serving a region, where the added annoyance of changing flights to local destinations would have to be endured.

By contrast, the Airbus philosophy was that bigger was better – it would construct a very big aircraft that could carry a large number of passengers from hub to hub, believing that this was where the future of the passenger market lay. Such a plane would enjoy the significant added advantage of much lower fuel consumption per seat/kilometre. The company envisaged a double-deck jumbo aircraft that could carry 550 passengers in a three-class configuration, but with an ultimate capacity of 850 passengers if needed. After intense consultations with major airlines, in 1994 a new standard in aviation was set when Airbus signified its intention to build the biggest commercial airliner ever. The project, at that time referred to as the A3XX, would put Airbus at the forefront of the aircraft manufacturing industry.

Airbus promised unparalleled fuel efficiency, with a target of more passengers per flight and a 15 per cent lower operating cost in fuel burn per seat than the Boeing 747-400. With the budget for the ambitious project set at US$11 billion, Airbus was staking its future on the aircraft. The planned break-even point was 250 aircraft sales, with a price tag of US$280 million apiece; fifty firm orders were needed to get the project off the ground. First to sign on the dotted line was Emirates Airlines, followed soon after by Singapore, Qantas and Virgin Atlantic.

PRODUCTION GOES AHEAD

In 2000, Airbus announced that production would go ahead, and the new aircraft was christened the A380. The main assembly hangar was constructed in Toulouse, France, where the parts from the Airbus consortium’s constituent companies in France, Germany, Spain and Britain were to be assembled into completed aircraft. The main wings were to be built in Britain, the tail section in Spain, and the fuselage in France and Germany. This presented the monumental logistical task of transporting all the parts to Toulouse for assembly. Smaller parts were to be flown to Toulouse in a specially modified Airbus A300 aircraft called the Beluga, aptly named after the white whale with its distinctive bulging head. The larger sections, like the wings and fuselage, however, were too big to fit into the Beluga. Instead, they were to be shipped by barge and then transported 200km (124 miles) by land over country roads to the main assembly hanger. Of particular interest was the passage of the fuselage through the sleepy French village of Levignac, where only centimetres separated the huge structure from the buildings of the main street. It was expected that A380 fuselages would creep through the streets of the village at the rate of one every week once production was in full swing.

In the summer of 2004, as construction of the first aircraft began, rumours of problems with the wiring started to emerge, suggesting that the assembly process could be delayed. Airbus cranked up its work rate with round-the-clock shifts, however, and managed to meet the deadline for the A380’s public unveiling in Toulouse in January 2005. Amazingly, only three years had elapsed since the first metal had been cut for the project in January 2002. Three months later, on a beautiful spring morning on 27 April 2005, the first flight of the A380 took place. The super jumbo, with a crew of two senior test pilots, Claude Lelaie and Jacques Rosay, who jointly captained the aircraft, and four test-flight engineers lifted off in front of 50,000 spectators. The test flight lasted three hours, fifty-four minutes and was a great success.

DELAYS

Behind the euphoric scenes, however, the Airbus production teams were faced with creeping delays in the manufacturing schedule. During the Paris Air Show, in June 2005, the first of a series of production delays was announced, putting back delivery of the first A380 by six months. In the meantime, to satisfy the aviation authorities that the aircraft could be operated safely in all conditions, the rigorous 2,500hr flight certification programme continued. Another six-month delay was announced in the summer of 2006 at the Farnborough Air Show, much to the disappointment of the launch customers.

Another six-month delay was announced in the summer of 2006 at the Farnborough Air Show, much to the disappointment of the launch customers. Airbus was still experiencing a problem with the wiring, as the French- and German-built fuselage sections did not seem to match. Then it was discovered that the two fuselage production teams were using different computer software for their production plans. As a result, it was decided that all plans would comply with the French software program, requiring a revamp of German equipment and manufacturing processes.

A third and final delay, resulting in the project being set back a further year, was announced in the autumn of 2006. Thus, the first production aircraft was delivered two years later than originally intended. The delay meant that Singapore Airlines, the first to fly the A380, did not receive its first aircraft until October 2007. In the meantime, final certification from the regulatory authorities to operate as a commercial airliner had been received in December 2006.

FIRST COMMERCIAL FLIGHT

In May 2007, the first A380 to be delivered to Singapore Airlines, with manufacturer serial number 003, was rolled out of the production hangar and released for trials prior to delivery in October. The airline inaugurated the first ever A380 commercial flight from Singapore to Sydney, the SQ380, on 25 October 2007.

CHAPTER 3

PRE-DEPARTURE PREPARATION

DOORS AND ACCESS

Back on the ramp at Heathrow, the pilots undergo a final security check as they enter the aerobridge before boarding the aircraft at main deck door one left (M1L). The three doors of the total of sixteen that are normally used for passenger boarding are M1L, main deck door two left (M2L) and upper deck door one left (U1L). Main deck doors two right (M2R), four left (M4L) and five left (M5L), and the upper deck one right (U1R) are opened for catering uplift and servicing personnel.
