What is the difference between LR and ER?
ER ( extended range ) is the improved base model with a longer range. The LR ( long range ) version has an additional fuel tank installed and hence an bigger MTOW.

What is LR Boeing?
A: ER is short for “Extended Range” and LR is short for “Long Range”. Both are marketing terms used by Boeing to describe different configurations to 777–200 and -300 aircraft. The differences have to do with how the aircraft was configured to meet goals requested by the commercial aircraft industry.
Why did the 777 200lr fail?
Larger fuel tanks made the aircraft heavy to fly, while rising fuel prices also rendered it expensive to operate. Airlines who operated the type sometimes found that they had trouble starting ultra-long-haul routes due to the amount of fuel required.
Can planes fly Pacific Ocean?
Weather Patterns. Most flights are planned to minimize the time spent over bodies of water, since storms are more likely to occur over water than land. The weather over the Pacific Ocean is often turbulent, and there are many thunderstorms in parts of the Pacific, so it’s not a safe environment to fly a plane.
What happened to the Boeing 777-200LR?
The Boeing 777-200LR is one of the longest range aircraft in the world at 8,555 nautical miles (15,843 km), even longer than the Airbus A380 and the Boeing 747. But despite being ahead of its time and destined to operate incredible routes, the aircraft never really became successful… because of its long-range focus.
What is the range of the Boeing 777-200LR?
As we have established, the 777-200LR had a range of 8,555 nautical miles, or 15,843 km, thanks to factors such as its impressive fuel capacity. The aircraft also had the advantage of only two engines compared to its rival, the similarly-ranged Airbus A340-500.
Who makes the engines for the Boeing 777-200LR Worldliner?
Both the 777-200LR and 777-300ER (Extended Range) were launched in February 2002 by Boeing and GE Aircraft Engines at the request of airlines that wanted an airplane with additional flexibility to serve the nonstop routes passengers demand. GE Aircraft Engines makes the 777-200LR Worldliner’s engines.
Which is more popular – the Boeing 777-200ER or the LR?
