Why are flights sometimes faster?

Clear-air turbulence. Jet streams are, at their most basic, high-altitude air currents caused by atmospheric heating and the inertia of the earth’s rotation—and they’re the reason why flights from west to east are faster than the same route traversed in the opposite direction.

Can planes fly faster to make up time?

It’s a familiar scenario, but can pilots actually make up time? The short answer is yes. The longer answer is that the amount of recouped time is limited by several factors.

Why do flights sometimes take longer?

Riding on a river of air The reason it took so much longer to fly back is the jet stream, a river of fast-moving air high up in the sky. Jet streams generally blow from the west to the east around the Earth, often following a meandering, curved path just like a river on land.

Why do planes Increase speed up before landing?

Q: Why do planes speed up before landing? The airplanes do not increase speed before landing. But when landing gear and flaps are set to landing position, they create a lot of aerodynamic drag. Therefore, engine power is increased to maintain the approach speed.

Why can’t commercial planes fly faster?

Airplanes don’t fly faster because they burn more fuel at higher speeds, meaning that it isn’t economical. In addition, operating at higher speeds puts more stress on the engines as well as the airplane fuselage, which causes them to wear down faster.

Are airlines flying slower?

Despite advances in technology and increasingly better planes, flights are actually slower now than before. According to the MIT School Of Engineering, cruising speeds for commercial planes are between 480 and 510 knots these days, while they used to be 525 knots on a Boeing 707 plane in the 1960s.

How do planes accelerate?

Thrust is used to accelerate the aircraft, to change it’s velocity, and thrust is used to balance the drag when the aircraft is cruising at a constant velocity. For fighter planes high thrust is desirable. But some aircraft, like jet airliners, spend most of their existence in cruising flight balancing the drag.

How do airplanes go so fast?

To go “faster”, airplanes have two options: increase thrust or decrease drag. Trust is created by the engine and drag is created by anything that produces wind resistance.

Why do planes fly faster in one direction and not another?

The reason for the difference is an atmospheric phenomena known as the jet stream. The jet stream is a very high altitude wind which always blows from the West to the East across the Atlantic. The planes moving at a constant air speed thus go faster in the West-East direction when they are moving with the wind than in the opposite direction.

Why don’t airplanes fly faster at higher altitudes?

It’s called Mach Tuck and in order to avoid this, each airplane has what’s called a Critical Mach number or the highest airspeed the wing can reach before Mach Tuck sets in. Airliners stay below this threshold which is why they aren’t traveling at or very near the speed of sound. By the book, airplanes won’t fly faster at higher altitudes.

Why do planes fly in a west- east direction?

The planes moving at a constant air speed thus go faster in the West-East direction when they are moving with the wind than in the opposite direction. Every planet/moon has global wind that are mostly determined by the way the planet/moon rotates and how evenly the Sun illuminates it.
