Technically this is the so-called ‘stall speed’, where air passes over the wings fast enough to sustain altitude, and for small planes this can be less than 50km/h (31mph). But at such low speeds, the aircraft is easily destabilised, and could fail to leave the runway.
What’s the slowest a 747 can fly?
Different airplanes will require different speeds to take off. In order for a plane to take off, it must be going fast enough for the wings to generate enough lift to overcome the force of weight. A Boeing 747 under standard conditions must be going 296kph (184 mph) to take off.
Can a plane fly at 60000 feet?
Some aircraft can fly higher
Concorde has been the only significant exception amongst commercial aircraft. It could fly up to 60,000 feet due to the increased lift generated when flying at much higher speeds. At low altitudes, drag would prevent it from reaching its high speeds.
How fast must a plane fly to stay in the air?
But as you fly higher, the air becomes thinner, so the plane must travel faster to maintain lift. While liftoff speed is around 170 mph at sea level, a commercial airliner’s cruising speed is around 550 mph at 40,000 feet — where the air density is 10x thinner.
What is the slowest speed a fighter jet can fly?
It depends on weight and altitude, so there is no one answer, but it goes down to 100 knots and below. The most popular GA aircraft, the Cessna 172, has an official cruise speed of 122 knots.
What is the fastest jet in the world?
The 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.
What is the easiest jet to fly?
The Top 6 Easiest Planes to Fly
- J-3 Piper Cub.
- Diamond DA40 Star.
- Cessna 152.
- Piper Pa28.
- Cirrus SR22.
- Cessna 172 Skyhawk.
What happens if a plane flies too high?
When the plane gets too high, there is insufficient oxygen to fuel the engines. “The air is less dense at altitude, so the engine can suck in less and less air per second as it goes higher and at some point the engine can no longer develop sufficient power to climb.” …
Do Planes fly over Mount Everest?
Airplanes often avoid air paths that take them over Mt Everest or the Pacific Ocean. … 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.”
What is the highest a plane has gone?
Question: What is the highest altitude an airplane can fly? Answer: The highest commercial airliner altitude was 60,000 feet by Concorde. The highest military air-breathing engine airplane was the SR-71 — about 90,000 feet. The highest airliner flying today reaches 45,000 feet.
Why do planes stop in mid air?
No a plane doesn’t stop in midair, planes need to keep moving forward to remain in the air (unless they are VTOL capable). What it can do is simply turn around or go over/under the obstruction. VTOL means vertical takeoff and landing. It essentially means they can hover in place like a helicopter.
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. Flat maps are somewhat confusing because the Earth itself isn’t flat. Rather, it’s spherical. As a result, straight routes don’t offer the shortest distance between two locations.
Do planes turn their engines off?
“They’re still operating and powering crucial systems, but providing no push. You’ve been gliding many times without knowing it. It happens on just about every flight. “Obviously an idle-thrust glide is different from the engines quitting outright, but even then, the glide itself would be no different.”
How Slow Can a jet go?
So, when discussing fighter jets, one may ponder how slow can a fighter jet fly? The lowest speed a fighter jet can attain during controlled flight, typically ranges from 100knots to 200knots depending upon the design and other flight.
How Slow Can a f16 fly?
An F-16 can fly at speeds greater than Mach 2, more than two times the speed of sound. That means the fighter jet can hit in excess of 1,500 mph. The fighter in the video, however, was not going that fast. These low-altitude flybys occur regularly in the area where the video was taken and are often picked up on radar.
Can you stall a fighter jet?
most fighters have a thrust to weight ratio > 1, so they are more like rockets. Any aircraft can stall if the wing AOA exceeds the stall limit. … common cases of fighter jets and airliners stalling.
