Why can't planes fly straight up?


Why can't planes 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.


Do planes ever depart early?

Planes sometimes leave early if the pilot makes the call, but generally, flights that depart ahead of schedule are just a few minutes early. This shouldn't cause a problem as passengers are expected to be at the gate 15-30 minutes before and should have boarded the plane at least 15 minutes ahead of the departure time.


How far can a plane fly without running out of fuel?

Commercial airliners, such as the Boeing 747 and the Airbus A380, have a range of around 8,000 to 8,500 nautical miles. This means that they can fly for up to 20 hours without refueling, allowing them to travel long distances across the globe.


What is the 3 hour rule in aviation?

For flights landing at U.S. airports, airlines are required to provide passengers with an opportunity to safely get off of the airplane before 3 hours for domestic flights and 4 hours for international flights.


Can planes fly over Mount Everest?

Tim Morgan, a commercial pilot writing for Quora says aircraft can fly above 40,000 feet, and hence it is possible to fly over Mount Everest which stands at 29,031.69 feet. However, typical flight routes do not travel above Mount Everest as the mountains create unforgiving weather.


Why don t planes fly overnight?

A lot of airports have restrictions on night flights because of noise issues. Also some smaller domestic airports close at night. There are a few that leave late at night in order to take advantage of the time difference in the arrival city. There aren't more because there isn't much demand for them.


Can a plane stop in air before landing?

Techincally, there is only one way for the aircraft to remain hanging motionless in the air: if weight and lift cancel each other out perfectly, and at the same time thrust and drag cancel each other out too. But this is incredibly rare. To stay in the air and sustain its flight, an aircraft needs to be moving forward.


What temp can planes not fly?

But, is there an exact temperature that makes it too cold for a commercial airplane to fly? “There is not a specific temperature,” says Tom Haines, Senior Vice President of Media, Communications & Outreach at the Aircraft Owners and Pilots Association (AOPA).


Can a plane flip when landing?

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.


Do planes avoid the ocean?

Since it is preferable to crash land on solid ground, and ideally close to an airport where emergency services are accessible, most airlines prefer to fly over land. Most flights are intended to spend as little time as possible over water, since storms are more common over the ocean than on land.


How long can pilots fly in a day?

Flight times within the duty periods are restricted to a maximum of 8 hours for flight crews consisting of one pilot and 10 hours for flight crews consisting of two pilots. The 8-hour and 10-hour flight time limitations include any additional commercial flying performed by the flight crew during the period.


What is the 3 hour tarmac rule?

According to the Department of Transportation (DOT), there are tarmac delay rules that US airlines must follow: Carriers are not allowed to hold a domestic flight on the tarmac for more than three hours and an international flight for more than four hours, barring a couple of exceptions (like if the pilot deems it's ...


How high can a plane fly without oxygen?

And that at cabin altitudes above 14,000 feet pilots must use oxygen at all times. And that above 15,000 feet each occupant of the aircraft must be provided supplemental oxygen. All of this is spelled out in Federal Aviation Regulations Part 91.211.


Why do planes do not fly over the Pacific?

The most common reason is that there are no airstrips or airports on many of the small islands, so if a plane had to make an emergency landing, it would be difficult to find a place to land. Additionally, the Pacific Ocean is vast and remote, so if a plane were to go down, it would be very difficult to find.


How long can they keep you on a plane at the gate?

Maximum Time
In the United States, airlines are not allowed to keep passengers on the tarmac for more than three hours on domestic flights and four hours on international flights without allowing them to disembark. After this time, the airline must either return to the gate or provide alternate transportation.
