Do planes fly over Everest?
According Debapriyo, most commercial airlines avoid flying directly over the Himalayas.
This is because “the Himalayas have mountains higher than 20,000 feet, including Mt Everest standing at 29,035 feet.
However, most commercial airplanes can fly at 30,000 feet.” …
The Himalayan region has almost no flat surfaces..
What is the fastest jet in the world?
Lockheed SR-71 BlackbirdThe Lockheed SR-71 Blackbird is the fastest jet aircraft in the world, reaching speeds of Mach 3.3–that’s more than 3,500 kph (2,100 mph) and almost four times as fast as the average cruising speed of a commercial airliner. Key elements of the SR-71’s design made this possible.
Can an airplane stay in the air without moving?
A: 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. … To stay in the air and sustain its flight, an aircraft needs to be moving forward.
Why do planes have to fly at 30000 feet?
When they fly at 30,000 feet, they get less drag and therefore can reach those top speeds safely. Supersonic aircraft, including spy planes and fighter planes, can fly much higher and therefore resist drag better. They can produce greater thrust so that this thinner air doesn’t interfere with the engine’s efficiency.
How Slow Can a 747 fly?
Speeds vary according to performance, environmental conditions and weight but typically a fully loaded 747 on a normal long haul flight would take off from a typical length runway at around 160 knots which is 184 mph.
How fast does a plane have to fly to stay in the air?
Just how quickly do passenger aircraft fly? Commercial jet aircraft cruise at about 400 – 500 knots (460 – 575 mph / 740 – 930 kph) – read more to understand the background behind it. Speed can get a bit confusing when talking about an object moving through the air.
Why are planes flying slower?
“The main issue is fuel economy. Going faster eats more fuel per passenger-mile,” said Aeronautics and Astronautics professor Mark Drela. … According to Drela, today’s airplane builders actually favor a smaller, lighter, and therefore slower aircraft that peaks its fuel efficiency at slower speeds.
What is the average plane speed?
around 575mphAverage cruising speed for a passenger jet is around 575mph. That is, however, a patch on the top speed ever reached by an aircraft, a record held by the Lockheed Blackbird, which tickled 2,193mph in 1976.
Why do planes stop in mid air?
An airplane can slow down and reduce its speed while in flight. … If an airplane reduces its speed too much, it will of course stall and start dropping precipitously, at which time the airspeed usually also increases again.
Why do planes do not fly over the Pacific?
The primary reason airplanes don’t fly over the Pacific Ocean is because curved routes are shorter than straight routes. … Whether a commercial airline is flying from the United States to Asia or elsewhere, it will have the fastest and most fuel-efficient flight by performing a curved rout.
Do planes fly slower to save fuel?
FLYING SLOWER One of the biggest fuel savings has come from flying aircraft more slowly. From the perspective of fuel consumption, there is an optimal cruising speed for each aircraft based on altitude. Flying faster increases the amount of fuel burnt.
Why are planes so fast?
A jet engine essentially has a series of small blades rotating at a very high speed inside the engine. Drag is a force that all planes feel. … By having a plane with engines that produce a large amount of thrust, and designing it to be streamlined, an airplane can travel very quickly.
