Planes are usually flying in the stratosphere, which is the second major layer of the earth’s atmosphere.
Can a passenger plane stop in the air?
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.
Do airplanes fly in stratosphere?
Commercial jet aircraft fly in the lower stratosphere to avoid the turbulence which is common in the troposphere below. The stratosphere is very dry; air there contains little water vapor. Because of this, few clouds are found in this layer; almost all clouds occur in the lower, more humid troposphere.
Why can’t planes fly in the mesosphere?
The mesosphere starts at 50 km (31 miles) above Earth’s surface and goes up to 85 km (53 miles) high. As you get higher up in the mesosphere, the temperature gets colder. … Weather balloons and jet planes cannot fly high enough to reach the mesosphere. The orbits of satellites are above the mesosphere.
Do planes basically fly themselves?
Yes, airplanes are capable of “flying themselves” given that they have an autopilot that is coupled to a navigation system (most autopilots are). … Also, autopilots are spectacular at following planned routing, but altitude changes have to be entered by the pilot at the time the altitude change is desired.
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.
Can a plane fly with one wing?
No, an airplane cannot fly with only one wing. In order for a plane to stay stable in air, it has to maintain balance. With only one wing, the weight is shifted to one side of the plane.
What would happen if a plane flew 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.” …
What is the highest altitude a plane can fly?
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.
Which is the hottest layer of atmosphere?
The thermosphere is the hottest layer of the atmosphere.
Do planes fly above the ozone layer?
Ozone is poisonous and, in high enough concentrations, can cause headaches, irritation to the respiratory system, and can harm lung function. Aircraft flying above the Tropopause may therefore be flying through air with high concentrations of Ozone.
What is the coldest layer of the atmosphere?
Located between about 50 and 80 kilometers (31 and 50 miles) above Earth’s surface, the mesosphere gets progressively colder with altitude. In fact, the top of this layer is the coldest place found within the Earth system, with an average temperature of about minus 85 degrees Celsius (minus 120 degrees Fahrenheit).
How high can you fly without oxygen?
Federal Aviation Regulations say that without pressurization, pilots begin to need oxygen when they fly above 12,500 feet for more than 30 minutes, and passengers have to use it continuously above 15,000.
Can pilots open windows while flying?
How do pilots open the windows? It would not be possible to open the windows during normal flight. … When the aircraft is not pressurized, either on the ground or if depressurized during the flight (intentionally or due to accident), then they can be opened. On most modern aircraft, the opening procedure is the same.
Do pilots sleep while flying?
Do pilots sleep in flight? The simple answer is yes, pilots do and are allowed to sleep during flight but there are strict rules controlling this practice. Pilots would only normally sleep on long haul flights, although sleep on short haul flights is permitted to avoid the effects of fatigue.
Do pilots get free flights?
While pilots travel often, it isn’t always fun to do alone. As a pilot, it is likely that you will have access to discounted (and sometimes free) plane tickets for family and friends, which means good deals on great vacations.
