Why do planes not fly straight up?

Flight plans need to account for the curvature of the earth when they are created. Since the earth is three-dimensional, it would be impossible not to fly in an arc. Another reason that planes would choose to fly in a trajectory that resembles an arc is to account for the amount of traffic that will be in the air.

The Pacific Ocean is a massive body of water that will require an extremely large amount of fuel to fly across. Rather than flying directly across the Pacific Ocean, most commercial flights take curved routes because they are actually shorter than shooting straight across a distance.

During a belly landing, there is normally extensive damage to the airplane. Belly landings carry the risk that the aircraft may flip over, disintegrate, or catch fire if it lands too fast or too hard.

Altitude and emergency descent The leading reason for aircraft avoiding the region is the high average height of the terrain.

MORE DETAILS

The reason planes cruise at high altitudes is that they burn less fuel and can fly faster, as the air is less dense. At 30,000 feet and higher, it is also possible for aircraft to avoid weather systems, making it more comfortable onboard.

While it all comes down to your preferences, daytime flying has the upper hand when it comes to visibility. Because of the sunlight, any possible obstructions, such as rocks or mountains, are far easier to spot, making the likelihood of accidents much less and daytime flying the safer option by far.

The numbers are clear: flying is much safer than driving. You are much less likely to be involved in a plane crash than a car crash, and the vast majority of plane crashes don't involve any fatalities.

Overwater flights are dispatched with ETOPS requirements in mind to ensure that a diversion airport is always within reach, assuming that the engine failure or shut down doesn't lead to other problems with the aircraft.

Thanks to the low visibility and undeveloped infrastructure, flying over Antarctica is extremely difficult. Specifically, because of the strong magnetic fields that surround the polar regions, navigating there, no matter how well-equipped the airplane is in terms of instrumentation, can be particularly challenging.

In fact, the National Weather Service says passenger planes are struck by lightning an average of once or twice every year. But the last confirmed commercial airplane crash in the United States attributed to lightning occurred in 1967.
