How high do planes fly above sea level?

Commercial aircraft typically fly between 31,000 and 38,000 feet — about 5.9 to 7.2 miles — high and usually reach their cruising altitudes in the first 10 minutes of a flight, according to Beckman. Planes can fly much higher than this altitude, but that can present safety issues.

How do planes reduce altitude?

This is generally done with angle of attack and airspeed. If you lower the angle of attack or lower the airspeed you will lose lift causing the aircraft to descend (or descend faster, or climb slower). When flying most larger jets things are actually backwards to Govind’s flight control approach.

How planes take off and land?

Landing gear: Planes take off and land on sturdy wheels and tires, which are rapidly retracted into the undercarriage (the plane’s underbody) by hydraulic rams to reduce drag (air resistance) when they’re in the sky.

How high can a plane fly without oxygen?

When the altitude of an airplane is less than 12,500 feet, there is no supplemental oxygen required for anyone in a private plane. From 12,500 feet to 14,000 feet, supplemental oxygen must be used by the required flight crew for any portion of the flight that is more than 30 minutes.

How do planes take off?

According to a principle of aerodynamics called Bernoulli’s Law, fast-moving air is at lower pressure than slow-moving air, so the pressure above the wing is lower than the pressure below. This creates the lift that powers the plane upward, and is how the takeoff is actually able to take place.

What is the longest flight over water?

The travel time from one point to the other was 18.5 hours long…the longest ever passenger flight time in all of history….For the longest Oceanic Crossing, the following are the top three contenders:

• Sydney to Vancouver.
• Melbourne to Los Angeles.
• Auckland to Vancouver.
