Why are 737 engines flat on the bottom?
In order to resolve the problem of the new center of gravity, Boeing redesigned the engine pylons. The flattening of the engine’s nacelle provided extra clearance from the ground. Of course, the engine itself is not flat, it is circular because the fan is circular.
What makes the 737 MAX different?
The 737 MAX is a fourth-generation Boeing 737, re-engined with CFM LEAP-1B turbofans. The 737 MAX is based on earlier 737 designs, with more efficient CFM International LEAP-1B engines, aerodynamic changes, including its distinctive split-tip winglets, and airframe modifications.
What’s the difference between 737 and 737 MAX?
The 737 Max can fly farther and carry more people than the previous generation of 737s, like the 737-800 and 737-900. It also has improved aerodynamics and a redesigned cabin interior and flies on bigger, more powerful and more efficient CFM LEAP engines.
How long can a 737 fly without refueling?
Q: How many hours can a Boeing 737 fly without refueling? A: A Boeing 737-700 ER can fly more than 12 hours; other models vary depending on the fuel tanks that are installed. Standard tanks allow around seven hours.
Will the Boeing 737 MAX be safe?

What is 737 MAX called now?
Boeing appears to have started quietly dropping the “Max” from its 737 Max aircraft in the wake of recent air disasters, instead referring to a 737-8.
Are any airlines still flying 737 MAX?
After the Federal Aviation Administration (FAA) in November 2020 cleared the Boeing 737 Max to return to service, other regulators – notably those in Brazil, Canada, Europe and the UK – have done likewise. In all, 13 carriers are now flying the 737 Max on commercial services.
Which is higher A320neo or 737 MAX?
The actual distance depends on the engine installed and the weight and balance of the airplane at the time. But there isn’t a huge difference between the two planes. Comparing the figures, the current A320 is about 10 cm higher than the current 737 NG. The A320neo and the 737 MAX will be pretty close, with the MAX potentially getting 5 cm lower.
Why do we need less maintenance on 737 MAX?
Because of our aircraft design philosophy, you simply need to perform less maintenance on the 737 MAX. We continually examine every maintenance requirement and engineer a simple, robust aircraft that minimizes upkeep. And deliver the longest mean time between overhaul, maximizing maintenance-free operation.
What’s the difference between Boeing 737 and 737 MAX?
Open your way. Bin latches open with a push or pull. No fumbling or guessing. Thoughtful details that say passenger comfort counts. A difference of 0.3% seems minor. For a fleet of 30 it means: Boeing will guarantee maintenance costs and days out of service.
Why is the Boeing 737 NG engine not completely round in shape?
Why is a Boeing 737 NG engine not completely round in shape? It seems to be flat at the bottom and round at the top and sides. Earlier Boeing 737 versions (100 and 200) seem to have a more rounded shape.
