Today was a sad day for the aviation industry with Airbus officially cancelling the A380 project. However, while today marks the end of the A380, it doesn’t stop there. It seems as though the whole 4 engine aircraft market is slowly being drawn to a close.
The majority of 4 engine aircraft on the market are made up of three families. The A340, A380, and B747. One only needs to look at sales statistics to see that 4 engines are no longer better than 2. Even the B747, the Queen of the skies, is seeing lower than predicted sales of its latest iteration.
Why 4 Engines?
Four-engined aircraft have the advantage of being immune to ETOPS procedures over the Atlantic, something which made the A340 a popular choice for carriers in its heyday. Additionally, the A380 and B747 use four engines to produce a significant amount of thrust for their extraordinary payloads.
The problem with the four-engined aircraft is that even with more efficient engines, they use an awful lot of fuel. This is something that in today’s current climate of rising fuel prices isn’t particularly popular with many airlines.
Boeing Moves Away From 4 Engines
It’s almost as though Boeing saw the end of the A380 before it was even being produced. While the American aviation giant could’ve focused elsewhere, it pursued the B787, a widebody aircraft with one passenger deck and two engines. As such, the B787 has been a huge hit, with Airbus developing the A350 to compete with it.
The B787 is popular because it has lower passenger counts than the A380 while maintaining a similar range. Tie this with the dual engines on the craft, and it becomes much more profitable than the A380 on most routes, especially where passenger counts are low.
Market Favours Efficiency
Increasingly, with the rising cost of aviation fuel, airlines are looking to maximise their profits. This has made 4 engine aircraft less favourable due to the amount of fuel they guzzle. The A350, B777 and B787 will carry fewer passengers than the B747 and A380. However, they achieve this on similar, if not longer, ranges.
This has two main advantages. Firstly, less fuel is required to power 2 engines than is required for 4. Secondly, it is much easier to fill an A350 than an A380. As such it is easier for airlines to recoup the costs of a flight. While the A340 and A380 programs have been closed, the B747-800 isn’t faring much better. In October Simple Flying reported: “In the past year to date, only 12 B747s have been delivered. 10 of these aircraft were the freight version, including 7 for UPS. Of the 2 passenger aircraft, one was delivered to an unidentified customer, with the other being set aside for the United States Air Force Presidential Aircraft Recapitalization Program.”
