Airplane wings are shaped to make air move faster over the top of the wing. When air moves faster, the pressure of the air decreases. So the pressure on the top of the wing is less than the pressure on the bottom of the wing. The difference in pressure creates a force on the wing that lifts the wing up into the air.
Can commercial planes stay still in the air?
NO, at least not during landing. … When landing in strong head wind the pilots will use higher air speed. This is because strong winds have a nasty habit of changing in strength or direction quickly and if the head wind reduced suddenly, the plane would loose lift and crash.
Do commercial airplanes fly themselves?
Planes today are built to essentially fly themselves. It’s simultaneously a comforting and terrifying thought. On the one hand, the most common reason for plane crashes is human error, so it can be reassuring to know that aircraft are designed to be automated and, frankly, smarter than humans.
Why do commercial airliners fly at 35000 feet?
The “sweet spot” of flying is regarded as between 35,000 and 42,000 feet – too high and the oxygen becomes too sparse to fuel the engines, too low and the air resistance is greater. This optimum height is linked to the usual weight of a commercial jet – that is, heavier planes fly lower, and lighter higher.
Can a commercial plane fly without engines?
Can a plane fly if all its engines have failed? A passenger aircraft will glide perfectly well even if all its engines have failed, it won’t simply fall out the sky. Aircraft are designed in a way that allows them to glide through the air even with no engine thrust.
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 helicopters stop in mid air?
A helicopter that is flying forward can stop in mid-air and begin hovering very quickly. We’ll cover this signature maneuver next.
What do pilots do when not flying?
1. Catching Up on Rest. According to the FAA, pilots are required to have 10 hours of rest, including 8 hours of uninterrupted sleep, in between their shifts. … In fact, if a pilot is experiencing sleep deprivation, this can lead to safety issues and in-flight errors.
What do pilots say when landing?
Thank you.” To indicate the landing clearance or final approach, the Captain will either make the following announcement and/or blink the No Smoking sign. “Flight attendants, prepare for landing please.” “Cabin crew, please take your seats for landing.”
Do pilots actually fly planes?
How much of a flight does the pilot physically fly the plane? … Modern planes can land themselves but most pilots prefer to do it. We generally disengage the autopilot at around 2,000 feet and fly the plane for around two minutes.
Why planes do not fly over Tibet?
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.”
Do planes eject toilet waste?
Waste whizzes through the plumbing to the rear of the plane, where it’s stored in sealed tanks, well away from passengers, until the plane touches down. On a long-haul 747 flight, travelers might flush the toilets around 1,000 times, creating around 230 gallons of sewage—that’s a lot of waste!
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.” …
Can a 747 Glide?
For example, with a glide ratio of 15:1, a Boeing 747-200 can glide for 150 kilometres (93 mi) from a cruising altitude of 10,000 metres (33,000 ft).
Can a 747 land on an aircraft carrier?
Large commercial aircraft like a Boeing 747 or an Airbus A-380 simply cannot fit on the deck without the wings clipping the island or other deck antennas, etc, not to mention requiring landing rolls of over 3000 ft even in the most extreme short field attempts. … Yes but only with small aircraft.
Can an airplane land itself?
Yes a plane can land by itself using a system that is often referred to as “autoland”. The pilots can program the auto pilot to carry out the landing automatically whilst the pilots monitor the aircraft. … Automatic landings probably account for less then 1% of all landings on commercial flights.
